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

Abstract

The invention relates to cycloidal reducers. A box body interlayer water cooling high thermal power dynamic balance cycloidal 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 cycloidal 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 four cycloidal gears, pin wheel housings, needle pins, eccentric bearings and pins. The box body interlayer water cooling high thermal power dynamic balance cycloidal 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 can be achieved.

Description

【Technical field】 [0001] The invention relates to the improvement of a cycloid reducer, in particular to a water-cooled high thermal power dynamic balance cycloid reducer with a box interlayer. 【Background technique】 [0002] The prior art B and X series cycloidal reducers have a production history of nearly 50 years, and the products are distributed in many domestic departments. [0003] The main defect of the existing technology is that: because the domestic B and X series cycloidal reducers are not equipped with fans and other heat dissipation measures on the high-speed shafts, only relying on natural heat dissipation results in low thermal power, which makes the user have to increase one or two motors. Model selection, as stipulated in many mechanical theory monographs, will inevitably increase the cost. The greater the power, the more the cost will increase: for example, the rated 8255 type (weight 865kg, price 26,800 yuan), now add one The machine model is 8265 (weigh...

AI Technical Summary

Problems solved by technology

[0013] In order to solve the defect of low thermal power in the prior art, the purpose of the present invention is to provide a water-cooled high thermal power dynamic balance cycloid reducer with a box interlayer instead of natural heat dissipation to improve thermal power.
