Abstract

The invention relates to the deceleration technical field, and refers to a carrying welding robot planet cycloid decelerator comprising a housing, bearings, an output plate, bearing seats, a large end cap, a planet and a cycloid transmission piece; the features are that the bearing supports a rigid output cylinder in the housing; a housing end face is connected with the large end cap; the bearing seat is connected in the large end cap; the planet comprises a sun gear, a planetary gear and a crankshaft; the planetary gear is connected on the crankshaft; a crankshaft eccentric shaft head is provided with the bearing; three bearings support a round plate; the cycloid comprises a cycloid wheel, gear pins and pin wheel housings; the cycloid wheel is tightly matched with a bearing seat excircle; the gear pins comprise a first gear pin and a second gear pin; the pin wheel housings comprise a first pin wheel housing and a second pin wheel housing; the first pin wheel housing is fixed on the round plate; the second pin wheel housing can relatively rotate with an angle smaller than 1 degree. Backlash between the pin wheel housings, the gear pins and the cycloid is zero; the large end cap is provided with a window; a gear pin hole is obtained through linear cutting. The beneficial effects are that the carrying welding robot planet cycloid decelerator can adjust decelerator return difference, is high in half buried teeth carrying capacity, and the first and second bearings are not overly large when reduction ratio equals to 3-4.

Description

【Technical field】 [0001] The present invention is an improvement of "a new type of high-precision reducer for robots" (201510062865.5), relates to the technical field of planetary and cycloidal deceleration, and relates to a planetary cycloidal reducer for a welding robot. 【Background technique】 [0002] The invention patent "a new type of high-precision reducer for robots" (201510062865.5) published by the China Patent Office on May 20, 2015 is a novel invention. The monopoly of foreign countries on this technology and the core technology of high-precision reducers for robots with completely independent intellectual property rights will build my country's core competitiveness in this area and promote the development of my country's robot industry." [0003] The inventor claims that the invention has the following beneficial technical effects: [0004] "This patented technology adopts the structure of pin wheel movement and fixed epicycloid wheel, which simplifies the struct...
