Participate in country, a number of science and technology research project of Shenzhen, and achieved excellent results. The company is committed to information communication and new energy smart transmission mechanism, independent development of 4G base station antenna electrically controlled system, intelligent home, intelligent robot core driver module, in the international leading level. And HuaWei, Germany BOSCH, Panasonic and other many fortune 500 companies to establish a long-term strategic cooperative partnership.

Spur gear type gearheads are probably the best possible choice for relatively low torque applications. They tend to be quieter in operation and have a relatively low amount of internal friction as well. Engineers designing high accuracy positioning servos are occasionally surprised to find that many of the small gearhead series use non-integer gear ratios. This fact is often discovered after the engineer has repeatedly tried to reconcile motor encoder counts with gearhead shaft position only to find a small but persistent position error. At first glance, the use of non-integer gear ratios appears to have no apparent purpose (with the possible exception of frustrating servo designers).

There is a fundamentally sound reason for designing gearheads with such gear ratios, however, and the servo designer who has sufficient information will generally have no problems using them. In the process of cutting gears, there is a small but inevitable error in tooth profile that is introduced by such process parameters as tool-wear. The profile error usually manifests itself in the last tooth cut on a particular gear blank. Depending upon the machine set-up and extent of tool wear, the material remaining on the gear blank for last tooth may be more or less than required to form a perfect tooth profile. As a result, an error may be introduced in the profile of the last tooth.
