Modularized rolling mill speed reducer

Abstract

The invention discloses a modularized rolling mill speed reducer, and relates to the technical field of speed reducers. The modularized rolling mill speed reducer comprises an input transmission module, a planetary transmission module, a rolling transmission module and a foundation mounting module; an input gear shaft, an intermediate gear and a first connecting shaft are arranged in the input transmission module; the input gear shaft is meshed with the intermediate gear; a second connecting shaft is arranged in the planetary transmission module; the planetary transmission module is detachablyconnected with the input transmission module; an output shaft is arranged in the rolling transmission module; and the rolling transmission module and the planetary transmission module are detachablyconnected together. The modularized rolling mill speed reducer is formed by assembling the input transmission module, the planetary transmission module, the rolling transmission module and the foundation installation module; parts between the modules have high universality and high interchangeability; and therefore, the modularized rolling mill speed reducer has the advantages of the power densityratio is high, the maintenance cost is low, maintenance time is short, and the reliability of each module is not reduced under external impact load.

Description

technical field [0001] The present application relates to the technical field of reducers, in particular, to a modular rolling mill reducer. Background technique [0002] The rolling mill reducer is mainly used as a reduction transmission device between the prime mover and the working machine in the rolling mill, and plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator. In the existing technology, the rolling mill reducer has an integrated structure, and the power density ratio is too low. In practical applications, the rolling mill reducer has overload, vibration and other working conditions, and the reliability of the input gear pair is low, and harsh working conditions cannot be avoided. It affects other gear pairs. During maintenance, the whole machine needs to be hoisted, and the man-hours and costs are wasted. The parts between the rolling mill reducers are not universally replaceable, so the cost of s...

Problems solved by technology

In the existing technology, the rolling mill reducer has an integrated structure, and the power density ratio is too low. In practical applications, the rolling mill reducer has overload, vibration and other working conditions, and the reliability of the input gear pair is low, and harsh working conditions cannot be avoided. Affects other gear pairs. During maintenance, the whole machine needs to be hoisted, which wastes a lot of man-hours and costs. There is no universal replacement of parts between the rolling mill reducers, so the cost of spare parts storage is relatively high.
