Split combined belt pulley

Abstract

The invention provides a split combined belt pulley. The split combined belt pulley comprises two half pulley bodies. Axial positioning keys are arranged on one of the half pulley bodies. The axial positions of the two half pulley bodies are positioned through the axial positioning keys, and the two half pulley bodies are buckled into a whole. The two half pulley bodies are detachably connected. A sleeve wheel is arranged outside the whole in a sleeving mode. A half pulley body pressing cover is detachably connected with the end face of the tail end of an installed power shaft. A sleeve wheel pressing cover is detachably connected with the end faces of the tail ends of the two half pulley bodies. The split combined belt pulley has the beneficial effects that a traditional belt pulley is split into two parts, namely the two half pulley bodies, so that the tedious steps during maintenance of the belt pulley are greatly simplified and the replacing difficulty is lowered; the good position function is provided for installation of the two half pulley bodies by arranging the axial positioning keys, so that the two half pulley bodies are buckled more conveniently and accurately; the good axial positioning function is provided for the two half pulley bodies and a transmission device assembled with the two half pulley bodies by arranging the half pulley body pressing cover; the sleeve wheel is in key transmission with the half pulley bodies and positioned through a conical face, so that disassembling, assembling and positioning are convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a split combined pulley. Background technique [0002] At present, for various transmission shafts that output power, belt transmission is mostly used to realize the power transmission. Between each power shaft, a pulley matching the transmission belt must be installed, and the effective diameter of the pulley should be adjusted to achieve the required transmission ratio, output torque, speed, etc. for the transmission. Due to the wide variety of transmission belts, the connection modes and connection sizes of the pulleys and shafts connected to the transmission belts are various. It is precisely because of the variety of actual use requirements, the variety of transmission belts, and the distinction of shaft diameter and transmission mode of the transmission shaft that the structural form of the pulley installed on the transmission shaft has the characteristics ...

AI Technical Summary

Problems solved by technology

However, due to many reasons such as outdoor, humid, improper installation, and long-term disassembly, the pulley is very difficult to disassemble, or even impossible to disassemble.

[0003] In addition, between the motor shafts of different equipment, even if the shafts are of the same size, the production tolerances implemented by different manufacturers are not the same, or the old motor shafts have problems such as rust and damage, resulting in belts produced according to the same tolerance. Wheels are difficult to fit on output shafts of the same type, but different batches of different old and new condition

The above factors increase the difficulty of equipment maintenance and increase the number of pulley spare parts, making the replacement of pulleys a costly and difficult task
