Abstract

The invention discloses a self-circulation vertical speed changer, which comprises a box body, an oil pump and an input shaft arranged in the box body. An oil pumping pipe and an oil outlet pipe are arranged on the oil pump. The bottom end of the oil pumping pipe is connected to a lower part in the box body, and the top end of the oil pumping pipe is connected with the oil pump. The bottom end of the oil outlet pipe is connected with the oil pump, and the top end of the oil outlet pipe is connected to an upper part in the box body. The self-circulation vertical speed changer is simple and compact in structure and long in service life; and oil on the lower part of the box body is pumped to the upper part of the box body through the oil pump to realize the self circulation of oil supply, so that all gears and bearings of the speed changers can be lubricated.

Description

[0001] technical field [0002] The invention relates to the field of speed changers, in particular to a self-circulating vertical speed changer. Background technique [0003] The speed changer includes a speed reducer and a speed increaser. The form of the transmission is vertical and horizontal. When the vertical transmission is running, the oil will accumulate in the lower part of the box due to gravity, resulting in high oil pressure, which will bring difficulties to the sealing of the transmission box and shorten the life of the seal. If If the damaged seal is not replaced in time, the transmission will be damaged, thereby reducing the service life of the transmission. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a self-circulating vertical transmission, which can pump the oil from the lower part of the box to the upper part of the box, so as to ensure the stability of the oil pressure in the box, thereb...
