Abstract

The invention discloses a three-piece combined type planet frame machining method, and belongs to the field of planet frame machining. The method comprises the following steps: firstly, after a bearing seat, a planet carrier and an output shaft are coaxially combined and installed, machining precise bolt holes, and installing precise bolts in the precise bolt holes; secondly, when the bearing seat, the planet carrier and the output shaft are clamped, installing an alloy tip in the output shaft, wherein the top end of the alloy tip is in contact with the interior of the output shaft; thirdly, carrying out finish machining on a bearing seat supporting outer circle and an output shaft supporting outer circle; fourthly, installing the bearing seat, the planet carrier and the output shaft on aboring clamp; fifthly, finely boring a planet gear shaft hole; sixthly, carrying out scraping finish machining on the planet gear shaft hole by using a scraping cutter bar and a scraping cutter; seventhly, marking mounting positions of the bearing seat, the planet carrier and the output shaft during machining, and fixedly clamping the planet carrier and the output shaft on the boring clamp; and eighthly, machining a snap spring groove in the planet gear shaft hole of the planet carrier. According to the method, coaxial errors of assembling are reduced, the frame manufacturing precision is improved, and the influence of the assembling errors on the outer circle grinding procedure is avoided.

Description

technical field [0001] The invention relates to a three-piece combined planetary frame processing method, which belongs to the field of planetary frame processing. Background technique [0002] The planetary reducer is an important part of the large-scale heavy-duty mechanical travel drive. It has the characteristics of compact structure, large load-carrying capacity, high transmission accuracy and high efficiency. The main components of the planetary reducer include the center wheel, the planetary gear, the planetary frame, the planetary wheel shaft and the bearing, etc. The planetary frame is one of the important components of the planetary transmission, and its machining accuracy directly affects the performance of the planetary reduction mechanism. The planetary carrier can be roughly divided into five types, which are integral frame structure, welded structure, cast structure, cantilever structure with detachable side plate, integral structure and combined structure wit...
