Problems solved by technology

[0004] The ball screw is loaded by the nut raceway and the screw raceway, and the structure is complex; for high load, internal circulation is used, and there are many processing procedures, especially the reverse through hole for steel ball rolling to ensure infinite circulation of steel balls, which is complicated to manufacture , and the size of the nut becomes very large; in addition to the complexity of some screw nuts, the outer circle also needs to have gears or other connection devices that cooperate with transmission, making the complex processing itself more difficult and unstable. ;Because the raceway is a continuous circulation transmission of balls, the life is reduced, the transmission efficiency is low, and it does not have the function of clutch and reset

Embodiment 1

[0031] The screw rod 2 is a smooth screw rod; a threaded raceway 301 is processed in the inner hole of the nut jacket 3, and a step II303 is formed at the front end of the inner hole; 6 connected; the screw 2 and the cage 1 are connected through the steel ball 4 and the threaded raceway 301, and the clutch transmission device and reset device form a clutch transmission reset device.

[0032] Further as a priority program, such as Figure 6 As shown, the end of the inner hole of the nut cover 3 is processed with a step III304, and the nut cover 3 is also provided with a reset step 302. One end of the return spring 5 is fixed to the reset step 302, and the other end is fixed to the cage fixing seat. 6 fixed.

[0033] Further, the distance between the centers of the corresponding through holes 102 after the cage 1 is deployed is an integer multiple of the screw pitch.

[0034] Further, the thread raceway can be a single-start or multi-start thread, and the multi-start thread ra...

Embodiment 2

[0038] Such as Figure 7 As shown, the screw rod 2 is a screw rod processed with a threaded raceway, and the two ends of the screw rod 2 are processed with steps I201; the inner hole of the nut jacket 3 is processed into a smooth hole, and the end of the inner hole of the nut jacket 3 is processed with steps III304, the nut jacket 3 is provided with a reset step 302; the end of the cage fixing seat 6 is provided with a step IV 601, and the part of the step IV 601 is provided with a slot 602; the right end of the nut jacket 3 is arranged in the step IV 601, and the reset step 302 Set in the slot hole 602, when the gear 101 of the cage 1 is driven to rotate by an external force, and the reset step 302 is pushed to the left end by the force in the direction of the steel ball 4, at this time the screw rod 2 will move in a straight line and be pulled to the holding position. The gear 101 direction of the frame 1, when the spring fixing seat 7 contacts the left end surface of the nu...

Embodiment 3

[0042] As an equivalent alternative to Example 2, such as Figure 8 As shown, the screw rod 2 is a screw rod processed with a threaded raceway, and the two ends of the screw rod 2 are processed with steps I201; the inner hole of the nut jacket 3 is processed into a smooth hole, and the end of the inner hole of the nut jacket 3 is processed with steps III304; the step I201 at the left end of the screw mandrel 2 is fixed with a spring holder 7; the reset device is formed by connecting the spring holder 7 and the nut jacket 3 by a return spring; the clutch transmission device and the reset device form a clutch Transmission reset device.

[0043] Further, the distance between the centers of the corresponding through holes 102 after the cage 1 is deployed is an integer multiple of the screw pitch.

[0044] Further, the thread raceway can be a single-start or multi-start thread, and the multi-start thread raceway can use large-diameter steel balls 4 when the load is large, so that ...

Abstract

The invention relates to a ball screw releasing-engaging transmission and resetting device. The ball screw releasing-engaging transmission and resetting device comprises a releasing-engaging transmission device and a resetting device. The releasing-engaging transmission device comprises a nut sleeve, a lead screw, a holder and a steel ball. The holder is provided with a transmission gear used for transmission. A through hole is further machined in the holder. One end of the lead screw is provided with a step I, and the lead screw is arranged in the holder. The steel ball is arranged in the through hole formed in the holder, and the diameter of the steel ball is smaller than that of the through hole. A holder fixing seat is arranged on the holder. The end, close to the through hole, of the holder is further provided with the nut sleeve. The resetting device is arranged on the holder. The releasing-engaging transmission and resetting device is formed by the releasing-engaging transmission device and the resetting device. The releasing-engaging transmission and resetting device can convert rotation motion into linear motion and meanwhile can achieve the effect of a clutch and rapid resetting. In addition, the releasing-engaging transmission and resetting device is small in friction, high in transmission efficiency, low in noise, high in applicability and capable of greatly releasing workforce and improving production efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a clutch ball screw drive reset device. Background technique [0002] Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repeated force, and it has high precision, reversibility and high Features of efficiency. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. Its significance is to change the bearing from a sliding action to a rolling action. [0003] At present, the ball screw has the following shortcomings and defects: [0004] The ball screw is loaded by the nut raceway and the screw raceway, and the structure is complex; for high load, internal circulation is used, and there are many processing procedures, especially the reverse through hol...
