High-precision steel belt transmission and transmission method thereof

Abstract

The invention discloses a high-precision steel belt transmission and a transmission method thereof. In the existing steel belt transmission products, steel belt slip, steel belt deflection, transmission time delay and the like of the steel belt transmission system affecting the transmission precision exist all the time. The high-precision steel belt transmission comprises a rack, a driving steel belt wheel, a driven steel belt wheel, a Moebius steel belt, a wheel axle, a drive motor, an off tracking prevention range sensor group, an angular displacement sensor and a tensioning off tracking prevention mechanism. The tensioning off tracking prevention mechanism comprises a guide rail and an auxiliary assembly; and the auxiliary assembly comprises a sliding table,a stepping motor, a lead screw, a sliding block, a tensioning roller, an electric push rod and a tensioning range sensor. Compared with a common steel belt, the Moebius steel belt has higher off tracking prevention capacity. According to the actual load pressure variation, the high-precision steel belt transmission can adjust the tensile force of the steel belt in real time, can prevent slippage and also can control the pressure to the wheel axle within a reasonable range.

Description

technical field [0001] The invention belongs to the technical field of steel belt transmission, and in particular relates to a high-precision steel belt transmission device and a transmission method thereof. Background technique [0002] In the existing products, there are always problems affecting the transmission accuracy of the steel belt transmission system, such as steel belt slippage, steel belt deviation, and transmission time lag. Especially in long-distance steel belt transmission, these problems are more prominent. For the problems of steel belt slipping and transmission time lag, it can be solved by adjusting the tension of the steel belt; on the basis of ensuring that the steel belt does not slip on the pulley, take the tension as small as possible. For the problem of steel belt deviation, it can be solved by formulating a mandatory running track for the steel belt, or by adjusting the axis of the pulley to change the tension beam at the edge of the steel belt an...

AI Technical Summary

Problems solved by technology

[0003] The problem of the deviation of the steel belt can also be solved by the "climbing" effect ("Design of Steel Belt Precision Friction Transmission Test Bench" (Cao Pin et al., Mechanical Transmission, 2009, 33 (04): 42-44+79+135-136 )) to solve it, but in practical applications, since the size of the pulley is larger than that in the test bench, the "climbing" effect will be significantly reduced, and due to the waist drum wheel used to achieve "climbing" The manufacturing requirements are higher than those of ordinary steel pulleys, and there are not many practical applications
