Problems solved by technology

[0002] The transmission gear is one of the transmission accessories of hardware accessories. It plays a very important role in the transmission field. It is connected to the transmission shaft, drives it to rotate through the transmission shaft, and then transmits the transmission energy placed by the transmission shaft to the next through the gear. For a gear wheel, the tightness and firmness of the transmission gear and the transmission shaft have a great influence on the transmission efficiency, and the gear fit between the two transmission gears also affects the transmission. Not only that, the long-term wear of the gears is even more serious It is easy to cause the convex tooth to break from the root of the tooth, and the gear will definitely generate a lot of heat when it rotates, which will also have a certain impact on the transmission efficiency

Abstract

The invention provides a transmission gear, which includes a gear body, the gear body is composed of a gear seat and a tooth surface, the tooth seat is provided with a number of arc-shaped convex teeth, and the top of the arc-shaped convex teeth is provided with an arc tooth top , arc grooves are arranged between two of the arc-shaped convex teeth, four threaded fixing holes are symmetrically arranged on the tooth surface, and a fixed hole ring is arranged at the center of the tooth surface, and the fixed hole ring is provided with Bosses are provided. This kind of transmission gear has a simple structure and a unique shape. The top of the tooth is designed as an arc shape, the tooth groove is designed as a concave shape, and a reinforcing rib is added to make the gear and the transmission shaft fit closer and the transmission efficiency is higher.

Description

technical field [0001] The invention relates to a gear, in particular to a transmission gear, and belongs to the field of mechanical parts. Background technique [0002] The transmission gear is one of the transmission accessories of hardware accessories. It plays a very important role in the field of transmission. It is connected to the transmission shaft, drives it to rotate through the transmission shaft, and then transmits the transmission energy entrusted by the transmission shaft to the next through the gear. For a gear wheel, the tightness and firmness of the transmission gear and the transmission shaft have a great influence on the transmission efficiency, and the gear fit between the two transmission gears also affects the transmission. Not only that, the long-term wear of the gears is even more serious It is easy to cause the convex tooth to break from the tooth root, and the gear will definitely generate a lot of heat when it rotates, which will also have a certai...
