Non-transmission type automatic reversing structure based on machinery

Abstract

The invention discloses a non-transmission type automatic reversing structure based on machinery, relates to the technical field of mechanical transmission, and solves the problems of low reversing speed and difficulty in quick reversing due to the fact that a contactor is mainly used for controlling the rotation direction of a three-phase motor to switch the rotation direction in the conventionalrotating shaft reversing process. The non-transmission type automatic reversing structure based on machinery comprises a base. Two driven shaft frames are fixedly arranged on the two sides of the topof the base. The driven shaft frames are each of a T-shaped structure, and two driven shafts are rotationally arranged between the two sides of the tops of the two driven shaft frames. Two sets of reversing gears are fixedly arranged on the outer side of each driven shaft, the reversing gears are bevel gears, the tooth surfaces of the reversing gears on the same side are opposite, a quick reversing function is provided for the reversing shaft brackets by arranging a reversing shaft bracket and a sliding rack, and the hydraulic cylinder is used for driving the sliding rack to move, so the angle of the reversing shaft bracket can be adjusted by meshing the sliding rack with the tooth-shaped structure of the reversing shaft bracket.

Description

Technical field [0001] The present invention relates to the field of mechanical transmission technologies, and is specifically a mechanical non-driving automatic automatic commutation structure. Background technique [0002] The shaft is a cylindrical article in the middle of the bearing or in the middle of the wheel or in the middle of the wheel, but there are also fewer partial. The shaft is a mechanical part that is supported by rotating the part and swiring to transmit moving, torque or bending moments, is also the mainly used drive mode. [0003] A patented, for example, a patent number CN207677590U discloses a structure for positioning the commutator and the rotating shaft, including a shaft, a core, a commutator body, the core, and a winding, the iron core. On the side, a connecting sleeve is provided, and the connection sleeve is provided with a commutator body, the rotating shaft through the core, a connection sleeve, and a commutator body, and the interior of the connec...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a non-transmission automatic reversing structure based on machinery to solve the problem that the currently used rotating shaft reversing proposed in the above background technology mainly uses a contactor to control the steering of a three-phase motor to convert the direction of rotation. The speed is slow, which is not conducive to fast reversing, and it is impossible to realize the problem of fast reversing of the transmission system during the mechanical operation.
