Description
Technical field
This utility model relates to a kind of movement, in particular, relates to a kind of Double-worm gear hydraulic pitch movement.
Background technology
Movement is the critical component of YJSW315-6A torque-converters, and its quality directly influences the use of this torque-converters
Performance and used life.
Movement is made up of hubcap assembly, turbine group, impeller assemblies and wheel stand assembly, by the cover coupled with electromotor
Power is passed to impeller assemblies by wheel assembly, then by the hydraulic oil of intracavity, rotary power is passed to turbine group, then will by output shaft
Power is transferred to change speed gear box, finally delivers power to wheel and is operated.
Turbine group in movement is to be made up of turbine cover, turbine hub, first turbine and two-stage turbine and bearing at present.Wherein
Two-stage turbine is coupled with turbine hub by bearing, in order to reduce two-stage turbine axial motion, current method be outer race and
The cooperation of turbine hub bearing chamber uses interference fit.Therefore, outer race is subject to bigger radial compacting force, is running up
Time bearing wear loss serious so that bearing becomes the part that spoilage is the highest, directly affects the service life of movement.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of novel pair of turbine hydraulic moment changeable
Device movement, it is possible to reduce the radial compacting force that bearing bears, reduces loss and abrasion that bearing produces when running up, improves
Service life.
The purpose of this utility model is achieved through the following technical solutions.
A kind of Double-worm gear hydraulic pitch movement of the present utility model, the pump impeller being connected with hubcap including hubcap and
Pump impeller connect gear and wheel stand, be arranged at the turbine hub inside hubcap, described turbine hub passes on left clutch shaft bearing and cover
Wheel is connected, and connects two-stage turbine by the second bearing on the right side of described turbine hub, and the external diameter of described second bearing is less than or equal to
Corresponding turbine hub bearing chamber internal diameter, is provided with snap ring on the right side of described second bearing, described snap ring is embedded in the bearing of turbine hub
Chamber internal surface, the internal diameter of described snap ring is more than the outer ring internal diameter of the second bearing.
The difference of the bearing chamber internal diameter of described turbine hub and the external diameter of the second bearing is set to 0.001mm-0.035mm.
Described snap ring is snap ring.
Compared with prior art, the technical solution of the utility model is had the benefit that
(1), in this utility model, the external diameter of the second bearing is less than or equal to corresponding turbine hub bearing chamber internal diameter, and difference sets
It is set to 0.001mm-0.035mm, greatly reduces the turbine hub bearing chamber thrust to the second bearing outer ring so that turbine hub axle
Hold the fit system of room and the second bearing from before interference fit become being slidably matched, decrease the second bearing in fortune at a high speed
The loss produced when turning and abrasion, improve service life；
(2) in this utility model, on the right side of the second bearing, it is provided with snap ring, it is therefore prevented that the second bearing and two-stage turbine axial
Play, adds stability；
(3), in this utility model, snap ring is embedded in the bearing chamber inner surface of turbine hub, and the internal diameter of snap ring is more than the second axle
The outer ring internal diameter held, it is ensured that internal hydraulic oil can pass snap ring, enters between inner ring and the outer ring of the second bearing, profit
Plain besring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference: 1 hubcap；2 pump impellers；3 gears；4 wheel stands；5 turbine hub；
6 clutch shaft bearings；7 second bearings；8 two-stage turbines；9 snap rings.
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of Double-worm gear hydraulic pitch movement of the present utility model, including hubcap 1, described hubcap
1 has been bolted to connection pump impeller 2, and described pump impeller 2 has been bolted to connection gear 3, the endoporus of described gear 3 and pump
The endoporus of wheel 2 is all connected by bearing wheel stand 4.Be provided with turbine hub 5 inside described hubcap 1, on the left of described turbine hub 5 outside
Periphery is connected with hubcap 1 inner surface by clutch shaft bearing 6, and the inner surface on the right side of described turbine hub 5 is by the second bearing 7 even
Connect the outer circumference surface of two-stage turbine 8.The external diameter of described second bearing 7 is less than or equal to the internal diameter of corresponding turbine hub 5 bearing chamber,
The difference of the bearing chamber internal diameter of described turbine hub 5 and the external diameter of the second bearing 7 is set to 0.001mm-0.035mm, decreases turbine
Hub 5 bearing chamber thrust to the second bearing 7 outer ring, by the fit system of turbine hub 5 bearing chamber and the second bearing 7 by former
Interference fit has become being slidably matched, and decreases loss and abrasion that the second bearing 7 produces when running up.Described second axle
Hold and on the right side of in the of 7, be provided with snap ring 9, it is therefore prevented that the second bearing 7 and the axial float of two-stage turbine 8, add stability, described snap ring
9 is snap ring, and described snap ring 9 is embedded in the bearing chamber inner surface of turbine hub, and the internal diameter of described snap ring 9 is more than the second bearing 7
Outer ring internal diameter, it is ensured that internal hydraulic pressure oil circulation.
