specific Embodiment 3

[0075] For a device with a transmission ratio of 60 and a torque of 50KN, try to make a brief design process of a roller cam direct drive transmission mechanism.

[0076] Such as figure 1 Shown is the schematic diagram of the roller cam direct drive transmission mechanism. The brief design process is:

[0077] According to the mechanical strength required for a torque of 50KN, the roller model is φ100×60, the outer diameter is 100mm, the width is 60mm, the wall thickness between the cam grooves is 25mm, and the spiral groove lead arc length is 125mm.

[0078] The radius of the pitch line of the roller and groove = (125x60) / 2π = 1194

[0079] The arc C is the outer arc surface of the cam 3 and also the radius r of the outer end surface of the roller mounting seat hole on the rotating body 1. 1 , R 1 =1194-60 / 2=1164

[0080] On the revolving body 1 with a radius of r, a plane P perpendicular to the axis is set, and the point of intersection with the axis is the center of the revolving bod...

Abstract

The invention relates to the technical field of mechanical transmission, in particular to a roller cam direct drive transmission mechanism which is formed by locking a roller and a cam. The roller camdirect drive transmission mechanism comprises: a rotary body, a roller and a cam; the roller is mounted on the rotary body; the roller and the groove of the cam are interlocked with each other, and when the power drives the cam to rotate, the roller on the circumference of the rotary body enters from one end of the groove, in the locking of the groove, the roller is pushed out from the other endof the groove by a plurality of turns, but when the roller leaves the trimming section of the groove, the subsequent roller has passed the trimming section of the entering end, and advances into the groove, in the locking of the groove, the roller is pushed by a plurality of turns, the continuous rotary motion of the rotary body around a mandrel is formed by the roller without the return stroke only with the push stroke, and the roller cam direct drive transmission mechanism is formed. The technical solution of the present invention solves the direct driving problem of a large-sized rotary body that needs to be driven by a large and medium-sized device; the device structure is greatly simplified after a speed reducer is removed, and the technical effects such as large speed ratio, unrestricted torque, and low cost are obtained.

Description

Technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a roller cam direct drive transmission mechanism which is used for large and medium-sized transmission mechanisms and is formed by locking a roller and a cam. Background technique [0002] For a long time, the variable speed transmission mechanism has relied on the gear transmission mechanism as the main body. The main problems are that the single-stage transmission ratio is small, the manufacturing accuracy is high, the oil lubrication requirements are high, the housing, the mechanism is heavy, the large mechanism is difficult to manufacture, and the power input The output is complex, especially the simplification of the mechanism that is not suitable for modern mechatronics and the requirements of intelligent network control. [0003] On December 18, 2012, our company obtained a utility model patent, the patent name is "Worm Transmission Mechanism", the patent number i...
