Bearing grease lubricated SEW S-series speed reducer

Abstract

The invention relates to the technical field of machine speed reduction, and discloses a bearing grease lubricated SEW S-series speed reducer. The speed reducer comprises a base, a worm wheel, a worm and a driven gear, wherein the driven gear is connected to the worm, and the worm wheel is connected to an output shaft, and the speed reducer is characterized in that the two ends of the worm are supported in a hole of the wall of the base; and after the two sealed bearings, a space ring, a thrust bearing and a press cover connected to a bearing hole end face are successively mounted; the output shaft is supported in a corresponding hole in the wall of the base by means of a bearing and a sealed bearing, and sealing elements are respectively arranged at both sides of the bearing; and after the sealed bearing at the tail end of the output shaft, a space ring, a thrust bearing and a round end cover connected to a bearing hole end face are successively mounted. The bearing grease lubricated SEW S-series speed reducer has the beneficial effects that in a planetary reduction box, rolling bearings are lubricated by bearing grease, and gears are subjected to forced lubrication by gear oil, so the planetary reduction box has the most important technical effect that the bearings operate reliably, and thus the speed reducer is long in service life and low in noise.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical deceleration, and relates to an S series reducer for bearing grease lubrication SEW, which is an improvement of the four series of reducers R, F, K and S of SEW Company in Germany - oil lubrication for gears in the frame and bearings for rolling bearings Grease lubrication,. 【Background technique】 [0002] Germany SEW company R, F, K and S four series of reducers, is the most widely imitated model after the cycloid reducer in China, and it is widely used in tobacco machinery production lines, beer production lines, mining machinery... [0003] R series helical gear reducer is equivalent to my country's coaxial cylindrical gear reducer TZ series (JB / T7000-93); F series parallel shaft helical gear reducer is comparable to Nanjing High Speed ​​Gear Factory's YNS series (JB / T7000-93), The S series of Tangshan Metallurgical Mining Machinery Factory is comparable; the K series spiral bevel gear red...
