Description

Technical Field

[0001] The utility model relates to the technical field of reducer housings, in particular to a reducer housing which is easy to assemble. Background Art

[0002] Reducers are generally used in low-speed and high-torque transmission equipment. The purpose of deceleration is achieved by meshing the gear with fewer teeth on the input shaft of the reducer with the large gear on the output shaft to reduce the speed of the electric motor, internal combustion engine or other high-speed power. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio.

[0003] Most of the existing reducer cases currently include an upper shell and a lower shell. During assembly, external lifting equipment is often used to lift the upper shell to the top of the lower shell, and then lower the upper shell and align it for welding.

[0004] However, since the upper shell and the lower shell need to be installed by multiple bolts, the screw holes of the upper and lower shells need to be aligned, but the alignment process consumes a lot of time. Once the upper shell falls onto the lower shell, it is difficult for the staff to continue to adjust the position of the bolt holes of the shell. Therefore, a reducer housing that is easy to assemble is proposed. Utility Model Content
