[0003] The existing hollow integrated high-precision reducer has a complex structure, including an input shaft, cycloidal wheel, rigid disc, needle roller, pin shaft, pin sleeve, ring gear, output shaft, and bearings. To achieve high-precision, High service life, very high machining accuracy requirements and installation accuracy requirements for each component
[0004] In the prior art, when manufacturing the reducer, the input shaft is processed first, and then the bearing is installed on the eccentric position. The position where the bearing is installed on the eccentric position on the input shaft is called the bearing position, and then the input shaft positioning bearing is inserted on the input shaft. The position where the positioning bearing is installed on the input shaft is also called the bea

Embodiment Construction
[0030] Examples such as Figure 1-5 As shown, the processing method of the input shaft of the hollow integrated high-precision reducer includes the following steps:
[0031] 1. Forging the input shaft blank 111;
[0032] 2. Machining the inner hole of the input shaft blank 111, and controlling the dimension D4, which is the diameter of the inner hole of the input shaft blank 111;
[0033] 3. Machining the first positioning plane 113 and the second positioning plane 114 of the input shaft blank 111;
[0034] Clamp the right end of the input shaft blank 111, process the first positioning plane 113 of the input shaft blank 111, and then process the second positioning plane 114 based on the inner hole of the input shaft blank 111 and the positioning plane 113;
[0035] The first positioning plane 113 is the left end surface of the input shaft blank 111 , and the second positioning plane 114 is the right end surface of the input shaft blank 111 .
[0036] 4. Process the position...

Abstract
The invention discloses a processing method of an input shaft of an integral high-precision hollow speed reducer. The processing method includes the steps of forging a blank of the input shaft, processing an inner bore of the blank of the input shaft, processing a first positioning plane and a second positioning plane of the blank of the input shaft, processing a positioning pin hole in the blankof the input shaft, clamping and assembling the blank of the input shaft by one step, and finishing a first outer race, a second outer race and a third outer race of the input shaft respectively. Without weakening various functions of the speed reducer, the processing method, aiming to improve service life of the input shaft, reduces error accumulation during assembling by reducing number of parts, eliminates three bearing stations of the conventional input shaft, processes the inner races of bearings onto the input shaft directly to eliminate assembly error between the bearings and the bearing stations, and accordingly improves precision.
Description
technical field [0001] The invention relates to the technical field of high-precision reducer processing, in particular to a processing method for an input shaft (eccentric shaft) in a novel hollow integrated high-precision reducer.
