Description
Technical field:
The utility model relates to the engine drive mechanism of mechanical engineering field, specifically is a kind of ball screw engine drive mechanism.
Background technique:
Present motor mainly adopts connecting rod, working principle is that the piston in the cylinder is done reciprocal motion, drive the connecting rod and the crank that links to each other with connecting rod that is connected on the piston thus, make reciprocal circular movement around crankshaft center, thereby outputting power, the mechanical efficiency of this reciprocating mechanism generally has only 80%.
Summary of the invention:
The purpose of this utility model: in order to improve the mechanical efficiency of motor, propose a kind of new work engine based on ball screw transmission and gear drive, it utilizes ball screw transmission and gear drive the linear reciprocating motion of cylinder piston to be converted to the rotation motion of engine output shaft.The transmission efficiency of ball screw transmission generally reaches 96%, and gear-driven efficient also reaches 95%, so both comprehensive mechanical efficient is higher.
In order to realize the purpose of model utility, intend adopting following technology: the utility model structurally comprises: cylinder, piston, leading screw, gear, tooth sector, output shaft, oil cylinder and small piston, it is characterized in that: tooth sector is installed on the output shaft, and two gears are installed in respectively on two leading screws, and is arranged symmetrically in the both sides of tooth sector, one end of two leading screws is connected with piston in two cylinders respectively, and the other end is connected with two small pistons in the oil cylinder respectively; Tooth sector is by reaching the purpose of continuous rotation with engagement at intermittence of two gears, thus outputting power continuously; Connect by oil cylinder between two leading screws, promote mutually, realize the coupling that both move.
The utility model maximum characteristics compared with the prior art are: ball screw transmission and gear-driven efficient are very high, so the output power of its motor is big; Adopt parts such as general leading screw, gear to replace the parts peculiars such as bent axle of crank-connecting rod motor, manufacturing process and cost all reduce greatly.

Embodiment:
Present embodiment is by cylinder 1, cylinder 10, piston 2, piston 9, leading screw 3, leading screw 8, gear 4, gear 7, tooth sector 5, output shaft 6, oil cylinder 13, small piston 14 and small piston 15 constitute, it is characterized in that: tooth sector 5 is installed on the output shaft 6, gear 4 is installed on the leading screw 3, gear 7 is installed on the leading screw 8, and gear 4 and gear 7 are arranged symmetrically in the both sides of tooth sector 5, one end of leading screw 3 is connected with piston 2 in the cylinder 1, the other end is connected with small piston (14) in the oil cylinder 13, one end of leading screw 8 is connected with piston 9 in the cylinder 10, and the other end is connected with small piston 15 in the oil cylinder 13.Originally, piston 2 is positioned at the right stop of cylinder 1, and piston 9 is positioned at the left stop of cylinder 10.As shown in Figure 1, when cylinder 1 acting, piston 2 is from the right stop stop motion left of cylinder 1, promoting leading screw 3 is moved to the left, clockwise rotate by ball 17 driven gears 4, the tooth sector 5 that is meshed with gear 4 also begins to rotate counterclockwise, and promotes small piston 15 by oil cylinder 13 simultaneously, leading screw 8 moves right, make piston 9 from the left stop of cylinder 10 to the right stop move.
As shown in Figure 2, tooth sector 5 meshes with gear 4 earlier, turns over 180 ° counterclockwise.At this moment, tooth sector 5 is just in time thrown off with full-depth tooth wheel 4, and meshes with gear 7 immediately.In conjunction with Fig. 1 as can be known, cylinder 10 actings this moment, piston 9 promotes leading screw 8 and is moved to the left, driven gear 7 clockwise rotates, make the tooth sector 5 that meshes with gear 7 continue to turn over counterclockwise 180 ° (as shown in Figure 3), promote small pistons 14 by oil cylinder 13 simultaneously, leading screw 3 moves right, make piston 2 get back to right stop from the left stop of cylinder 1, this moment, output shaft was just in time finished week rotation.
After this, tooth sector 5 meshes with gear 4 once more, cylinder 1 does work once more, piston 2 from the right stop of cylinder 1 left stop move, tooth sector 5 continues to turn over 180 ° counterclockwise, piston 9 is got back to right stop from the left stop of cylinder 10 simultaneously ... such process circulation is carried out, thereby reaches the purpose that output shaft 6 is rotated continuously.
Because ball screw transmission and gear-driven efficient are all very high, so the utility model is energy-conservation than the crank-connecting rod engine drive mechanism.
