Box body interlayer water cooling high thermal power dynamic balance hypocycloidal reduction box

Abstract

The invention relates to cycloidal reducers. A box body interlayer water cooling high thermal power dynamic balance hypocycloidal reduction box comprises a box body, an input shaft, a transmission mechanism and an output shaft, wherein the input shaft, the transmission mechanism and the output shaft are arranged in the box body and are in successive transmission. The box body interlayer water cooling high thermal power dynamic balance hypocycloidal reduction box is characterized in that a connecting part of an inner cylinder and a circular end cover is arranged in the box body, a flange of the inner cylinder is connected with the output end face of the box body, an outer circle of the input end of the circular end cover is in close fit with an inner hole of the input end of the box body, the input end face of the circular end cover and the input end of the box body are in seal connection through the same annular pad, the inner wall of the box body and the outer wall of the connecting part of the inner cylinder and the circular end cover form an interlayer, water inlet valves communicated with the airtight interlayer are arranged on the top of the box body, drain valves communicated with the airtight interlayer are arranged on the lateral part of the box body, the input shaft is supported in the circular end cover through a bearing, the output shaft is supported in the inner cylinder through a bearing, and the transmission mechanism comprises cycloidal gears, hypocycloidal tooth rings, eccentric bearings and pins. The box body interlayer water cooling high thermal power dynamic balance hypocycloidal reduction box has the technical advantages that heat in an airtight interlayer water sleeve is exhausted from a water outlet valve and dissipated to the outside of the box body, the structure is simple and manufacturing cost is low; the water flow rate is adjusted so that thermal power can be close to mechanical power, and dynamic balance of operation of the four gears can be achieved.

Description

【Technical field】 [0001] The invention relates to a hypocycloidal speed reducer, in particular to a box interlayer water-cooled high thermal power dynamic balance hypocycloidal speed reducer. 【Background technique】 [0002] The prior art SB hypocycloid (also known as double cycloid) reducer has a history of nearly 20 years, but due to the difficulty in processing the hypocycloid ring gear, the domestic use is not as large as that of the cycloid. [0003] "The characteristics of (inner) cycloidal equidistant gears: double cycloidal meshing; approximate surface contact near the nodes; an oil-filled cavity is formed between the tooth profiles. Compared with the existing cycloidal pinwheel transmission, (1) hypocycloid The efficiency is more than 93%; (2) the bearing capacity of the hypocycloid is about 50% higher." (See: Paper "Development of Cycloid Equidistant Gears" Journal of China Textile University Vol.15No.2, 1989, Li Kezhi, Shen Peiji). [0004] The main defect of the ...

AI Technical Summary

Problems solved by technology

[0013] In order to solve the defect of low thermal power in the prior art, the object of the present invention is to provide a water-cooled high thermal power hypocycloidal reduction box with interlayer water cooling instead of natural heat dissipation to increase thermal power.
