Suspended-type gear speed reducer

Abstract

The invention provides a novel suspended-type gear speed reducer which comprises a box body and a two-stage gear speed reducing mechanism, wherein a grease fitting and a channel are arranged on an output hollow shaft, an O-shaped seal ring groove is arranged on the wall of an inner bore, the end face of the other end is equipped with a seal plate base, a one-way piston seal ring is installed on the seal plate base; a grease fitting is arranged on the seal plate base, the seal plate base is stuck in the inner cavity of the output hollow shaft by a spring retaining ring, thus the output hollow shaft and a shaft cannot be oxidized and rusted. Grease can be injected from the grease fitting arranged on the seal plate base so as to impel the output hollow shaft to separate from the shaft, thus the speed reducer can be completely disassembled. A separated bearing support is arranged, an external thread is sleeved on the bearing support, a bearing sleeve screw hole is arranged on the box body, the inner wall of the bearing sleeve is provided with a spring retaining ring groove and a flange plate is fixed on the box body through a bolt and an adjustable screw hole, thus the bearing can be freely rotated and adjusted, the bearing can be prevented from being worn in one direction and the interval between tapered rolling bearings can be easily changed and adjusted; as the box body is cast by using high-strength aluminum alloy material which is favorable to heat dissipation, thus the heat dissipating effect of the speed reducer is good.

Description

technical field [0001] The invention relates to the field of mining machinery and equipment, in particular to a suspended gear reducer. Background technique [0002] In recent years, my country's economy has developed rapidly, and all walks of life have shown a vibrant scene, especially metallurgical machinery, environmental protection machinery, road construction machinery, chemical machinery, food machinery, light industrial machinery, mining machinery, conveying machinery, construction machinery, Building materials machinery, cement machinery, rubber machinery, water conservancy machinery, petroleum machinery and other mechanization levels are constantly improving. Energy saving, environmental protection, and consumption reduction have become the development direction of the country. The international direction, the earth's resources are limited, we must reduce consumption and leave resources for future generations. [0003] The development of the reducer in our country ha...

Problems solved by technology

[0007] 2. The pull force of the transmission belt connected to the motor causes the input shaft bearing of the reducer to bear the pull force in one direction for a long time, which causes excessive wear and affects the service life of the bearing

[0008] 3. The cast iron shell is used, the bearing capacity of the output hollow shaft is heavy, and the compact space results in poor heat dissipation
