Description
Technical field
It the utility model is related to a kind of hydraulic capstan decelerator sun gear with limit function.
Background technology
Decelerator is the independent type closed driving device between prime mover and working machine.It is big that decelerator is generally used for the slow-speed of revolution
The drive apparatus of moment of torsion, the number of teeth on input shaft that motor, internal combustion engine or other power to run at high speed are passed through decelerator
Few gear engages the gear wheel on output shaft to reach the purpose of deceleration, and common decelerator also has several to same principle tooth
Wheel reaches the ratio between preferable slowing effect, the number of teeth of big little gear, is exactly gearratio.
At present, the main Types of domestic decelerator have cylinder gear speed reducer, cone gear reducer, worm reducer,
Gear-worm reducer, planetary reducer etc..Planetary reduction gear is so that its gearratio is big, transmission efficiency, compact-sized
The advantages that be widely used in every field, the sun gear of existing planetary reduction gear is solid generally by being welded with planet carrier
It is fixed, then be machined out, efficiency is low, it is necessary in tooth when machining vehicle device part profile, washing six side's boss, gear shaping, particularly gear shaping
Larger escape is reserved between root and six side's boss, so not only procedure complexity, the cycle is long, yield rate is low, parts move back
Produce substantial amounts of stress at cutter groove, and after be heat-treated yielding planet carrier strain cracking, this there is certain deficiency
Part.
Utility model content
Technical problem to be solved in the utility model is overcome the deficiencies in the prior art, there is provided a kind of processing technology letter
It is single, the process-cycle is short, the hydraulic capstan decelerator sun gear with limit function of high yield rate and long product lifecycle.
Technical scheme is used by the utility model：Hydraulic capstan decelerator sun gear described in the utility model is using cold
The processing technology one-shot forming of extruding, the hydraulic capstan decelerator sun gear include the sun tooth set gradually from left to right
Portion, spacing ring portion and six side's boss portions, at the tooth root of the sun teeth portion with circular arc at the left contact of the spacing ring portion
Excessively, the outline of the spacing ring portion is higher by the sun teeth portion and the six sides boss portion.
Six side's fit depressions of the six sides boss portion and planet carrier, the spacing ring portion closely connect with the planet carrier
Touch.
The centre of the hydraulic capstan decelerator sun gear is provided with the through hole for being available for input shaft to pass through.
The beneficial effects of the utility model are：Because hydraulic capstan decelerator sun gear described in the utility model uses cold-extruded
The processing technology one-shot forming of pressure, the hydraulic capstan decelerator sun gear include set gradually from left to right sun teeth portion,
Spacing ring portion and six side's boss portions, at the tooth root of the sun teeth portion with circular arc mistake at the left contact of the spacing ring portion
Degree, compared with prior art, the processing technology of the hydraulic capstan decelerator sun gear simple, the process-cycle for one-shot forming
It is short, moreover, former escape is replaced by spacing ring portion, this avoid the machining stress that slot is brought, the spacing ring portion
Can also be with planet carrier tight structure, it is important that at the tooth root of the sun teeth portion and at the left contact of the spacing ring portion
Circular arc is excessive, tooth can be made to form the effect similar to reinforcement, the stress intensity of such sun gear is high, and the hydraulic capstan subtracts
Fast device sun gear can coordinate with planetary gear split, without being heat-treated after being carried out again after welding, so the utility model processing technology
Simply, the process-cycle is short, high yield rate and long product lifecycle.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is front view of the present utility model.
Embodiment
As shown in Figure 1 and Figure 2, hydraulic capstan decelerator sun gear described in the utility model uses the processing technology of cold extrusion
One-shot forming, the hydraulic capstan decelerator sun gear include set gradually from left to right sun teeth portion 1, spacing ring portion 2 with
And six side's boss portions 3, the limit excessive with circular arc at the left contact of the spacing ring portion 2 at the tooth root of the sun teeth portion 1
The outline of position ring portion 2 is higher by the sun teeth portion 1 and the six sides boss portion 3, when the six sides boss portion 3 uses and planet
Six side's fit depressions of frame, play positioning action, and side and the planet carrier of the spacing ring portion 2 are in close contact, played
Position-limiting action, the centre of the hydraulic capstan decelerator sun gear are provided with the through hole 4 for being available for input shaft to pass through.
By using such structure and processing mode so that processing technology of the present utility model is simple for one-shot forming
Single, the process-cycle is short, moreover, former escape is replaced by the spacing ring portion 2, the processing brought this avoid slot should
Power, the spacing ring portion 2 can also be with planet carrier tight structures, it is important that at the tooth root of the sun teeth portion 1 with it is described spacing
Circular arc is excessive at the left contact of ring portion 2, and tooth can be made to form the effect similar to reinforcement, the stress intensity of such sun gear
Height, and the hydraulic capstan decelerator sun gear can coordinate with planetary gear split, without being heat-treated after being carried out again after welding, so
The yield rate of product has obtained great lifting.
The utility model is applied to planetary reduction gear field.
