45# Steel Mechanical Transmission Spur Gear Cylindrical Gear

Products: 45# Steel mechanical transmission spur gear cylindrical gear

1. Spur gear is a type of cylindrical gear, often referred to as spur gear, which is mainly used in mechanical transmission. Its main feature is that the tooth line coincides with the central axis, and the tooth profile of the spur gear always remains straight with respect to the axis. Spur gears can rotate in both directions. In order to enable the gears to rotate in both directions, the tooth profiles on both sides of the gear teeth are composed of involute curved surfaces with the same shape and opposite directions.

2. The tooth surface of a spur gear is a straight line, so its tooth surface angle is zero degrees. The contact area of the tooth surface is relatively small, so the noise and axial load during transmission are also relatively large. In addition, the spur gear has a long tangential length of the tooth surface and a large force-bearing area, which can withstand greater loads, but is also more susceptible to wear.

Our company was formerly known as Changsha Double Star Gear Industrial Co., Ltd, which was established in 1994. It is a directly affiliated university-run enterprise founded by Central South University Professor Zeng Tao, the leading expert on spiral bevel gears in China. It was later renamed as Changsha Senjie Gear Co., Ltd (abbreviated as "CSG") in 2016. CSG is a production R&D base specializing in professional design, reserch, manufacture and sales of high-quality small module spiral bevel gears and high reduction hypoid gears and cylindrical gears. In 2023, Hunan Dinghan New Material Technology Co., Ltd. was established as a specialized international export business department. CSG has strong scientific research and development capabilities and is also equipped a full set of advanced equipment including seven-axis five-linkage CNC spiral bevel gear grinding machines and gear milling machines. By making the best use of the scientific and technological achievements and equipment of the Gear Research Institute of Central South University, machanical processing, heat treatment and testing. We have developed high-quality products featuring high reduction, high speed, heavy load, low noise and less teeth for users.

With the quality policy of "scientific and technological innovation, quality first, being first-class firm and customer‘s satisfaction", we have won the trust of well-known domestic and abroad enterprises with stable and excellent quality. It is committed to be a pioneer of the industry of China's small-module spiral bevel gears, and is dedicated to providing service for any related industry requiring industrial robots, CNC turning and milling compound power tool turrets, industrial sewing machines, reducers, bicycles, power tools and aeromodelling. We sincerely look forward to your cooperation!
