Abstract

The invention provides a novel roller lead screw transmission device and a using method thereof, and relates to the technical field of mechanical transmission parts. The roller lead screw transmission device comprises a mounting base, first threaded grooves which are evenly distributed are fixedly connected to the outer diameter of the periphery of a lead screw, second threaded grooves which are evenly distributed are fixedly connected to the inner wall of the periphery of a nut, and a front reverser and a rear reverser are arranged in the middles of the rear end of the right side and the front end of the left side of the nut respectively. Conical rollers which are uniformly distributed are connected in the second threaded grooves in a sliding manner. The lead screw rotates to drive the nut to move forwards on the lead screw through the first threaded grooves and the second threaded grooves, and meanwhile the conical rollers are driven to circulate in an inner circulation closed loop formed by the lead screw, the nut, the front reverser and the rear reverser, so that the nut moves relative to the lead screw; and the conical rollers serve as transmission media, so that the contact area between the nut and the lead screw is increased, and the device can bear larger axial thrust, and the device is worthy of being vigorously popularized.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission components, in particular to a novel roller screw transmission device and a method for using the same. Background technique [0002] Ball screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion. 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 at the same time have the characteristics of high precision, reversibility and high efficiency. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instrument. [0003] At present, the existing ball screw transmission device has a small contact area between the nut and the screw shaft, weak axial thrust, poor transmission effect, and inconvenient opera...
