Electric timing belt wheel

Abstract

The invention belongs to the technical field of mechanical equipment, and particularly relates to an electric timing belt wheel. The electric timing belt wheel comprises a belt wheel body provided with protrusions. A central circular hole penetrating through the belt wheel body and the protrusions is formed in the axis of the belt wheel body and the protrusions. End covers are arranged on the protrusions, and shaft holes communicated with the central circular hole are formed in the axis lines of the end covers. A bearing mounting hole is coaxially formed in one side, close to the belt wheel body, of the end cover with the shaft hole. Bearings are installed in the bearing mounting holes, and a stationary shaft is coaxially arranged on the two end covers through the bearings. The part in thecentral circular hole of the stationary shaft is provided with stator coils. Rotor magnet yokes are arranged on the inner side of the belt wheel body around the stator coils, and permanent magnets are arranged on the inner sides of the rotor magnet yokes around the stator coils. According to the electric timing belt wheel, a driving device and a motor are arranged in the belt wheel, so that spaceoccupation is reduced, convenience is provided for the design of equipment or production line and maintenance, and the automation and intelligence of production equipment are promoted.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to an electric synchronous pulley. Background technique [0002] The synchronous pulley drive is composed of a closed ring-shaped belt with equidistant teeth on the inner peripheral surface and the corresponding pulley. When moving, the teeth of the belt mesh with the tooth grooves of the pulley to transmit motion and power. It is a kind of meshing transmission, so it has various characteristics of gear transmission, chain transmission and flat belt transmission. Widely used in automobiles, textiles, printing and packaging equipment, sewing equipment, office equipment, laser engraving equipment, tobacco, financial equipment, stage lighting, communication food machinery, medical machinery, steel machinery, petrochemical, instrumentation, various precision machine tools It is also widely used in various automation and intelligent industrial production. However, it is fo...

AI Technical Summary

Problems solved by technology

However, it is found in use that the driving device of the existing synchronous pulley is mostly arranged outside the synchronous pulley, which takes up a certain space and causes unnecessary troubles for the overall planning of the equipment or the overall planning of the production line; In the case of synchronous pulleys, if one is broken, all the wheels need to be removed, which is inconvenient for maintenance

In addition, in the synchronous belt drive, in order to prevent deviation due to the non-parallel axis of the pulley, it is usually necessary to install retaining rings on both sides of the pulley, and the retaining rings can be fastened to the side of the pulley by screws. Making corresponding via holes and threaded holes on the retaining ring and pulley and assembling them is complex and costly; if riveting, spot welding and other methods are used to connect the pulley and retaining ring, riveting or welding equipment is required at this time. Low processing efficiency, poor reliability, uneven appearance of the pulley
