As shown in fig. 1, the linear/rotational conversion mechanism 10 of the present application includes a spur gear and rack pair and a rotating shaft 100, and the spur gear 101 is coaxially and rotatably provided on the rotating shaft 100. The linear/rotational conversion mechanism 10 further includes a first bevel gear 110 and a second bevel gear 120 coaxially provided on the rotation shaft 100, and a transmission bevel gear 160 connecting the first bevel gear 110 and the second bevel gear 120. The linear/rotational conversion mechanism 10 further includes a first unidirectional rotation portion 130 and a second unidirectional rotation portion 140 having the same unidirectional rotation direction. The first bevel gear 110 drives the rotating shaft 100 to rotate unidirectionally through the first unidirectional rotating portion 130, and the second bevel gear 120 drives the rotating shaft 100 to rotate unidirectionally through the second unidirectional rotating portion 140. The spur gear 101 is provided on one end surface of the first bevel gear 110.
The spur gear 101 and the rack 102 pair are a mechanism for changing a reciprocating linear motion into a bidirectional rotary motion, that is, the reciprocating motion of the rack 102 is changed into the bidirectional rotary motion of the gear. The spur gear 101 and the rack 102 are paired, and specifically, the rack 102 corresponds to a reciprocating linear input mechanism of the linear/rotational conversion mechanism 10. The rotation shaft 100 is an output part of the one-way rotation of the linear/rotational conversion mechanism 10, and the rotation shaft 100 is a bearing part of the spur gear 101, the first bevel gear 110, the second bevel gear 120, the first one-way rotation part 130, and the second one-way rotation part 140.
The end face of the first bevel gear 110 is connected with a spur gear 101, the rotation of the spur gear 101 drives the first bevel gear 110 to rotate, and the first bevel gear 110 drives the second bevel gear 120 to rotate through a transmission bevel gear 160. The meshing angle of intersection between the first bevel gear 110 and the drive bevel gear 160 is 90 °, the meshing angle of intersection between the drive bevel gear 160 and the second bevel gear 120 is 90 °, and the first bevel gear 110 and the second bevel gear 120 are identical bevel gears, such that the first bevel gear 110 and the second bevel gear 120 rotate coaxially on the rotation shaft 100. The first bevel gear 110 and the second bevel gear 120 rotate in opposite directions.
The first and second bevel gears 110 and 120 rotate the rotation shaft 100 through the first and second unidirectional rotation parts 130 and 140, respectively. If the first unidirectional rotation portion 130 and the second unidirectional rotation portion 140 rotate in the clockwise direction, they are locked and rotate counterclockwise. When the first bevel gear 110 rotates clockwise, the first bevel gear 110 drives the rotating shaft 100 to rotate clockwise through the first unidirectional rotating portion 130, the second bevel gear 120 rotates counterclockwise, and the second bevel gear 120 rotates relative to the rotating shaft 100 through the second unidirectional rotating portion 140, so that the clockwise rotation of the rotating shaft 100 is not affected. On the contrary, when the first bevel gear 110 rotates counterclockwise, the second bevel gear 120 drives the rotating shaft 100 to rotate clockwise through the second unidirectional rotating portion 140. Therefore, the clockwise or counterclockwise rotation of the first bevel gear 110, i.e., the reciprocating linear motion of the rack 102, can be converted into the unidirectional rotation of the rotating shaft 100.
It should be noted that the counterclockwise and clockwise references refer to the rotation direction of the output end of the rotating shaft 100, such as clockwise or counterclockwise when viewed from left to right in the drawing.
The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings.
Example 1
In this embodiment, the first bevel gear 110 and the second bevel gear 120 of the linear/rotational conversion mechanism 10 are rotatably provided on the rotating shaft 100. The first unidirectional rotation unit 130 includes a first end-face type ratchet 1301 coaxially disposed on the rotation shaft 100, and a ratchet 1302 disposed on an end face of the first bevel gear 110 and unidirectionally engaged with the first end-face type ratchet 1301. The second unidirectional rotation portion 140 includes a second end-face type ratchet 1401 coaxially disposed on the rotation shaft 100, and a ratchet 1302 disposed on an end face of the second bevel gear 120 and unidirectionally engaged with the second end-face type ratchet 1401. The non-return directions of the first end-face ratchet 1301 and the second end-face ratchet 1401 are the same.
As described above, the first unidirectional rotation portion 130 and the second unidirectional rotation portion 140 are both engaged with each other in a one-way manner using end-face ratchet teeth. As shown in the figure, when the first bevel gear 110 rotates clockwise, the ratchet teeth 1302 on the first bevel gear 110 slip on the first end-face type ratchet 1301, the second bevel gear 120 rotates counterclockwise, and the ratchet teeth 1302 on the second bevel gear 120 and the second end-face type ratchet 1401 are engaged, so as to drive the rotating shaft 100 to rotate counterclockwise. Similarly, when the first bevel gear 110 rotates counterclockwise, the ratchet 1302 on the first bevel gear 110 is engaged with the first end-face type ratchet 1301, so as to drive the rotating shaft 100 to rotate counterclockwise, the second bevel gear 120 rotates clockwise, and the ratchet 1302 on the second bevel gear 120 slips on the second end-face type ratchet 1401. Accordingly, it can be seen that the rotating shaft 100 outputs counterclockwise rotation regardless of whether the first bevel gear 110 rotates in the forward direction or in the reverse direction.
In another embodiment, if the one-way engaging direction of the first one-way rotating portion 130 and the second one-way rotating portion 140 is clockwise, the rotating shaft 100 outputs clockwise rotation.
Specifically, the first end-face-type ratchet 1301 and the second end-face-type ratchet 1401 are each an end-face-type ratchet with a single-face having a ratchet, and the two end-face-type ratchets are slidably disposed on the rotating shaft 100. The linear/rotational conversion mechanism 10 further includes a compression spring 150, and the compression spring 150 is sleeved on the rotating shaft 100 and is disposed between the two end-face tooth ratchets.
In the above, two end-face tooth type ratchets with ratchets on one side are adopted, and the compression spring 150 is additionally arranged between the two end-face tooth type ratchets, so that the first end-face type ratchet 1301 and the second end-face type ratchet 1401 have larger engaging force with the first bevel gear 110 and the second bevel gear 120 respectively, the ratchets are prevented from slipping in the buckling direction, and the buckling stability of the ratchets is better and more effective. Meanwhile, the rigidity of the ratchet teeth in the sliding direction is weakened, and the sliding between the ratchet teeth is facilitated. The accuracy of the interval between the first and second bevel gears 110 and 120 is reduced, and the error of the accuracy is compensated by the compression spring 150.
In another embodiment, the first end-face ratchet 1301 and the second end-face ratchet 1401 are end-face tooth type ratchets with ratchets on both sides, and the end-face tooth type ratchets are fixed on the rotating shaft 100. The first unidirectional rotation part 130 and the second unidirectional rotation part 140 are formed by an end face tooth type ratchet wheel with ratchets on both sides and the ratchets 1302 on the end faces of the first bevel gear 110 and the second bevel gear 120, so that the number of components is reduced, the coaxiality of the first bevel gear 110 and the second bevel gear 120 is better, and the transmission consistency is better.
In this embodiment, the teeth on the first bevel gear 110, the second bevel gear 120 and the drive bevel gear 160 are all helical teeth. The helical gear transmission has the advantages of small abrasion and small noise of transmission.
Referring to fig. 2 and 3, the present embodiment further provides an engine 1, which includes a reciprocating linear driving mechanism 20 and the linear/rotational conversion mechanism 10. The reciprocating linear driving mechanism 20 drives the rack 102 to do reciprocating linear motion.
As described above, the rack 102 is driven to reciprocate by the reciprocating linear driving mechanism 20 so that the rotary shaft 100 outputs continuous unidirectional rotation. The force application direction of the rack 102 is perpendicular to the connecting line of the gear joint point of the rack 102 and the gear center, so that the force application of the rack 102 to the straight gear 101 is always kept to be maximum, and the driving point is the best mechanical driving point.
In this embodiment, the two reciprocating linear driving mechanisms 20 are disposed at two ends of the rack 102, and the two reciprocating linear driving mechanisms 20 have the same moving direction. Two reciprocating linear driving mechanisms 20 drive the rack 102 to move at two ends of the rack 102, one reciprocating linear driving mechanism 20 pushes the rack 102 to move, and the other reciprocating linear driving mechanism 20 pulls the rack 102 to move. Thereby providing uniform and stable power to the bi-directional movement of the rack 102.
It is understood that the power source of the reciprocating linear driving mechanism 20 can be one or a combination of a plurality of mechanisms of an oil pump hydraulic mechanism, an electromagnetic induction type linear motor, an air pump pneumatic mechanism and a fuel explosion type linear mechanism. The reciprocating linear drive mechanism 20 of the present embodiment is a linear motor.
The engine 1 further includes an engine body 30, and the linear/rotational conversion mechanism 10 is provided in the engine body 30. The rotary shaft 100 extends from the engine body 30 and rotates relative to the engine body 30. The rotary shaft 100 serves as a power output shaft of the engine 1.
In this embodiment, the rack 102 extends from the engine body 30, and the two reciprocating linear drive mechanisms 20 are disposed outside the engine body 30. A guide rail is provided on the engine body 30, and the rack 102 reciprocates on the guide rail. The movement direction of the rack 102 is more accurate and stable by adding the guide rail on the engine body 30.
The engine 1 with the linear/rotary conversion mechanism 10 has large, stable and continuous driving force, and is an energy-saving engine 1 with high utilization rate of power input.
Example 2
As shown in fig. 4, in the present embodiment, the first unidirectional rotation portion 130 and the second unidirectional rotation portion 140 with the linear/rotational conversion mechanism 10 are both unidirectional bearings. A one-way bearing is one that is free to rotate in one direction and dead locked in the other direction. The metal shell of the one-way bearing contains a plurality of rolling shafts, rolling needles or rolling balls, and the shape of a rolling seat (cavity) of the one-way bearing enables the one-way bearing to roll only in one direction and generate great resistance in the other direction.
In this embodiment, the one-way bearing is clockwise rotated and counterclockwise locked. A one-way bearing is provided between the first bevel gear 110 and the rotation shaft 100, and a one-way bearing is provided between the second bevel gear 120 and the rotation shaft 100. When the first bevel gear 110 rotates clockwise, the first bevel gear 110 slips on the rotating shaft 100, the second bevel gear 120 rotates counterclockwise, and the second bevel gear 120 drives the rotating shaft 100 to rotate counterclockwise through the one-way bearing. Similarly, when the first bevel gear 110 rotates counterclockwise, the first bevel gear 110 drives the rotating shaft 100 to rotate counterclockwise through the one-way bearing, the second bevel gear 120 rotates clockwise, and the second bevel gear 120 slips on the rotating shaft 100. Therefore, the clockwise or counterclockwise rotation of the first bevel gear 110, i.e., the reciprocating linear motion of the rack 102, can be converted into the unidirectional rotation of the rotating shaft 100.
By adopting the one-way bearings as the first one-way rotation portion 130 and the second one-way rotation portion 140, the one-way rotation performance is better, the rotation friction is small, and the switching rotation impulse force of different bevel gears is small.
In all examples shown and described herein, any particular value should be construed as merely exemplary, and not as a limitation, and thus other examples of example embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
