Description

Technical Field

[0001] This utility model belongs to the field of coupling technology, and in particular relates to a drum-shaped roller coupling. Background Technology

[0002] For roller couplings, torque is transmitted by setting steel columns or steel balls between two concave semicircular grooves on the inner and outer bushings. Since the contact surface is an arc, it has the characteristics of low contact stress and low wear. Furthermore, the small gap between the cylindrical groove and the contact surface of the steel ball / steel column results in precise, smooth, and low-noise motion.

[0003] Because of the relatively complex structure of its coupling, and the fact that lubricating oil is prone to leakage in harsh working conditions such as high temperature, high dust and impact load, if it is not maintained in time, it will wear out too quickly and become less stable. Therefore, designing a roller coupling that is easy to maintain is a problem that needs to be solved by people in this field. Summary of the Invention

[0004] The purpose of this utility model is to provide a drum-shaped roller coupling. Through the design of the intermediate connecting plate and the design of the constricted end of the inner key sleeve, the two can be concentrically positioned during installation and can adjust the distance between the two shafts, which is beneficial for concentric positioning and subsequent precise installation. At the same time, it can form a side oil cavity connected to the drum-shaped roller. With the design of the oil filling groove and oil passage on the intermediate connecting plate, it can clean, replace, replenish and maintain the lubricating oil at the drum-shaped roller, which is convenient for the operator and can ensure the stability and service life of the coupling.

[0010] The constricted end is positioned opposite the flange and forms a side oil cavity between them;

Oil nozzles connected to the oil injection grooves are provided on the peripheral side of the intermediate connecting plate. Oil passages are provided on both sides of the intermediate connecting plate, and the two ends of the oil passages are connected to the oil injection grooves and the side oil chambers, respectively.

[0013] Furthermore, the intermediate connecting plate and the flange peripheral side are provided with platform surfaces on opposite sides, the platform surfaces of the intermediate connecting plate and the flange are flush, and the oil nozzle is set on the platform surface of the intermediate connecting plate.
