Abstract

The invention discloses a belt wheel transmission component. The belt wheel transmission component comprises a transmission shaft, a belt wheel and a fixing seat. A mounting hole is formed in the fixing seat in a penetrating manner. The transmission shaft is supported inside the mounting hole. One end of the transmission shaft is provided with the belt wheel. The two ends of the fixing seat are provided with bearing end covers. The bearing end covers are arranged on the transmission shaft in a sleeving manner. A seal assembly is arranged at the outer end of each bearing end cover in a sealed manner. Each seal assembly comprises an outer cover, a seal disc and a seal ring. The outer end of each bearing end cover is provided with a step-shaped groove in the axial direction. Each step-shapedgroove is composed of a small hole diameter groove, a connecting groove and a large hole diameter groove from inside to outside in a communicating manner. The diameter of each small hole diameter groove is less than that of the corresponding connecting groove. The diameter of each connecting groove is less than that of the corresponding large hole diameter groove. Each seal ring is mounted in thecorresponding small hole diameter groove in a clamped and inlaid manner. Each seal disc is arranged in a cavity form by the corresponding connecting groove and the corresponding large hole diameter groove in a clamped and inlaid manner. Each outer cover is detachably connected with the corresponding bearing end cover and tightly presses the outer end of the corresponding seal disc. The belt wheeltransmission component is simple in design, good in locating effect and convenient to mount and adjust.

Description

technical field [0001] The invention relates to a transmission machine, in particular to a pulley transmission part. Background technique [0002] Belt drive is a kind of mechanical transmission that utilizes a flexible belt tensioned on a pulley for motion or power transmission. According to different transmission principles, there are friction belt drives that rely on the friction between the belt and the pulley, and there are also synchronous belt drives that rely on the teeth on the belt and the pulley to mesh with each other. Belt transmission has the characteristics of simple structure, stable transmission, buffering and absorbing vibration, transmission of power between large shaft distances and multiple shafts, low cost, no need for lubrication, and easy maintenance. It is widely used in modern mechanical transmission. Regardless of the design of the belt drive, there is a problem of severe wear between the pulley and the drive shaft due to uneven radial force. Thi...
