Abstract
The invention belongs to the field of reduction gears, provides an input suite of a cycloidal reducer and a machining method of the input suite and aims to solve the problems that an existing input suite is of a split structure, easy to damage and high in production and manufacturing cost. The input suite comprises an input shaft, the periphery of the input shaft is integrally provided with two annular protrusions in the circumferential direction, and the circle centers of the annular protrusions are arranged to be eccentric with the axis of the input shaft; the eccentric directions of the two annular protrusions are opposite to each other. According to the input suite of the cycloidal reducer and the machining method of the input suite, the input shaft, an eccentric sleeve and a bearing inner ring (equivalent to the eccentric sleeve of the input suite) are integrated, the structure is simplified, cumulative tolerance is shortened, and precision is greatly improved; due to the fact that the input suite is shrunk into a whole, an inner hole of the input suite can be enlarged, a motor shaft can directly stretch into the eccentric inner hole, the length is shortened, the size of an input end cover is further shortened, rigidity of workpieces is greatly increased, and the phenomenon of shaft breakage cannot occur anymore; nearly 30% of raw materials are saved, so that machining time is saved by 50%, cost is greatly lowered, and the blank in China is filled up.
Description
Technical field
The invention belongs to speed reducer field, particularly relate to a kind of input external member and processing method thereof of cycloid speed reducer.
Background technique
The input part of tradition cycloid speed reducer is made up of input shaft, eccentric bushing, bearing inner race.Drive the running of cycloid wheel with eccentric center principle, it is as follows to there is defect in it:
1, owing to being three part combination, accumulation property tolerance is large, affects eccentric precision, and producing the defect such as temperature rise, noise, working life is short affects the positive machine quality of cycloid.
2, due to three combinations, eccentric bushing, bearing inner race must ensure certain thickness (preventing fracture), endoporus is made to be subject to size restrictions, input shaft is made to be forced to change carefully, cause the excessive frequent generation breaking axis of input shaft load, just the size of input part entirety is done greatly, the material that waste is more like this, and the quality of whole product and volume are increased.
3, material cost and processing charges all high costs.
Summary of the invention
The present invention seeks to the deficiency that exists for the input part of existing cycloid speed reducer and the input external member of the cycloid speed reducer of the integral structure provided.
The present invention is achieved by the following technical solution:
An input external member for cycloid speed reducer, comprises input shaft, and be provided with annular projection in the peripheral circumferential integral type of input shaft, the center of circle of this annular projection and the axle center of input shaft are set for the eccentric.
Described annular projection is two, and the eccentric direction of two annular projections is contrary.
The inside of described input shaft is provided with the hole slot inserted for driving source output terminal, is processed with keyway at the inwall of this hole slot.
Protrude from annular projection in the axis of input shaft and be provided with the fixed end installed for bearing.
A processing method for the input external member of cycloid speed reducer, comprises the steps:
Step one, rough forging, forges columniform blank by forging machine;
Step 2, rough turn, product in step one is carried out machined into, first clamps one end of blank, surfacing and cylindrical;
Step 3, rough turn, the product end in step 2 is carried out hole, rough turn hole;
Step 4, rough turn, turned around by the product in step 3, car other end, then by the cylindrical of clamp vehicle two bias;
Step 5, keyseat, is placed on the keyway on slotting machine in machining hole by the product in step 4;
Step 6, heat treatment, heat-treats the product in step 5, to improve the hardness of product;
Step 7, fine finishing, carries out grinding machine mill processing process by each for the product in step 6 face.
The rough turn mill amount all staying 0.3mm in described step 2, step 3, step 4.
Beneficial effect of the present invention: this patent is integrated input shaft, eccentric bushing, bearing inner race (being equivalent to the eccentric bushing in the application) three, and its advantage is as follows:
1, designs simplification, reduce accumulation property tolerance, substantially increase precision.
2, owing to being reduced into one, its endoporus can be strengthened, and motor shaft directly can reach eccentric inner hole, shortens length, also makes input end cap size shorten, has increased considerably the rigidity of workpiece, never again off-axis phenomenon occurs.
3, the raw material owing to saving nearly 30%, machining period saves 50%, and cost significantly declines, and has filled up Chinese blank.
