Accompanying drawing explanation
Fig. 1 is the structural representation of slave wheel of the present invention.
Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art with reference to description literary composition
Word can be implemented according to this.
As it is shown in figure 1, slave wheel structure of the present invention, including wheel hub 6 and the tire 7 being arranged on wheel hub 6, described
Wheel hub 6 is driven rotation via deceleration device 15, for reducing overall volume and improving axial strength, in the present invention by driving motor
Described wheel hub 6 specifically includes hub end cap 61 and is perpendicular to described hub end cap 61 and extends and the hub wall 62 that formed, described tire 7
Fix and be sealed on the lateral wall of described hub wall 62；The medial surface of described hub end cap 61 and the medial wall of described hub wall 62 are closed
Enclosing space 63 in formation, described driving motor and deceleration device 15 are arranged in described interior space 63.Compared to prior art
In slave wheel structure, owing to effectively reducing the axial length of slave wheel in the present invention, therefore make the intensity of slave wheel significantly
Strengthen；Further, the body construction of the design mobile transfer car that heretofore described slave wheel structure can be convenient is used,
Can effectively increase loading capacity.
In slave wheel structure of the present invention, described driving motor includes stator 2 and is arranged at stator 2 center
Rotor 1；The output shaft 17 of described rotor 1 is connected with the power shaft 14 of described deceleration device 15, the output of described deceleration device 15
Axle 16 is fixing with wheel hub 6 to be connected, and drives described wheel hub 6 synchronous axial system, drives described hub end cap 61 to synchronize to turn specifically
Dynamic, thus drive tire 7 to rotate, described slave wheel is moved forward and backward.It should be noted that described deceleration device not this
Prerequisite assembly in bright described servo crawler driving whell, if field demand is that the rotating speed of wheel hub is significantly lower than driving motor
Output speed, then must arrange deceleration device in the outfan increase driving motor.For field demand be wheel hub rotating speed with
Drive the situation that the output speed of motor is equal, then can be not provided with aforesaid deceleration device, but the output of motor will be driven
Axle is connected directly to wheel hub by shaft coupling.
For lift structure stability, and can improve lifting capacity, in the present invention, also on described stator 2, fixed cover is provided with
Bearing block 3, described bearing block 3 is provided with bearing group 8, and (described bearing group 8 includes at least one bearing, the concrete bearing arranged
Quantity different with the size of hub wall and different according to the difference of loading capacity)；Inner ring 81 and the described bearing block of described bearing group 8
3 are relatively fixed connection, and the outer ring 82 of described bearing group 8 is relatively fixed with the medial wall of described hub wall 62 and is connected.
In slave wheel structure of the present invention, described bearing block 3 is cylinder, and described stator 2 is from described cylinder rear end
Opening 34 and insert cylinder interior 35.The front end of described cylinder is closed, and offers recessed at the front end center of this closing
Accommodation space 36, the bottom center at this accommodation space 36 offers the through hole 37 leading to cylinder interior 35；Described deceleration device
15 are installed in described accommodation space 36, and described rotor of output shaft axle 17 is set out from described through hole 37.In actual manufacture
In, described rotor of output shaft axle 17 can be simultaneously set to the power shaft 14 of deceleration device 15, even rotor of output shaft axle 17 and power shaft
Unite two into one both 14.For strengthening the stationarity rotated, bearing also can be set described rotor of output shaft axle 17 is supported.
In order to avoid bearing group 8 occurs axial displacement, the present invention is provided with indent at the front end outer wall of described bearing block 3
Mounting groove 18, the inner ring 81 of described bearing group 8 is arranged in described mounting groove 18；Additionally, also include inner pressure ring 13, described interior
Pressure ring 13 is fixedly installed on the end of bearing block 3, and supports residence and state the bearing inner race 81 of bearing group 8.So, bearing inner race 81
An end face 12 edge that is mounted groove 18 limit, another relative end face 11 is pressed within ring 13 and limits, thus not
Can make bearing group 8 that axial displacement occurs.
Further, also can the bearing outer ring 82 of bearing group 8 be carried out spacing, to prevent bearing group 8 from axial displacement occurring.
The specifically medial wall at described hub wall 62 offers the fixing groove 19 of indent, and the bearing outer ring 82 of described bearing group 8 is set
It is placed in described fixing groove 19；Additionally, also include outer press ring 31, described outer press ring 31 is fixedly installed on the end of hub wall 62,
And support residence and state the bearing outer ring 82 of bearing group 8.As it is shown in figure 1, bearing outer ring 82 end face 21 is by fixing groove 19
Edge limits, and another relative end face 22 is limited by outer press ring 31, from without there is axial displacement.Further, by
In the stability of bearing group 8 self structure, bearing outer ring 82 has certain rigidity relative to bearing inner race 81, and phase will not occur
To movement, also make wheel hub 6, relative to bearing block 3, axial displacement will not occur.So, so that it may by the end at bearing block 3
Connection assembly 5 is set and wheel hub 6 is installed on mover (such as, by the most uniform for described bearing block 3 for outward
Portion's fixture connects fixing fixing hole).Now, described bearing block 3 function as bracing frame, its inner containment drives
Motor, and external support plays wheel hub 6.
Because the work on the spot environment of mover and the bearing group 8 requirement to working environment, the outer press ring in the present invention
31 specifically include bottom surface ring 32 and the inner edge from described bottom surface ring 32 extends vertically the ring wall 33 of formation.Wherein, described bottom surface
Ring 32 is set in parallel in the end of described hub wall 62 and is fixedly installed in the end of hub wall 62 by bolt 10.Described
Ring wall 33 is inserted between the medial surface of hub wall 62 and the outer surface of bearing block 3, and its end is supported residence and stated bearing group 8
Bearing outer ring 82 (being i.e. resisted against end face 22).It should be noted that for guaranteeing that outer press ring 31 mutually moves relative to bearing block 3
Do not interfered, can will be left suitable space between ring wall 33 and bearing block 3, specifically can freely rotatable be unlikely to again to fall
Enter the hard thing of the impurity such as gravel to be as the criterion.
In the present invention, the also end at stator 2 is provided with the encoder 4 controlling to drive motor, and described encoder 4 can be selected for
The magnetic coder of anti-vibration, to realize the accurate control driving motor.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed
Using, it can be applied to various applicable the field of the invention completely, for those skilled in the art, and can be easily
Realizing other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
