Description

Gear coupling
Technical field
The utility model relates to a kind of gear coupling, mainly is used in industries such as rail vehicle.It connects transmitting torque through crowned teeth and end tooth; Use bellows to connect static relatively ring gear and form sealed cavity, thereby can use the coupling of oil lubrication.
Background technique
Coupling is a kind of machinery the most frequently used in the modern industrial engineering, is parts that connect diaxon or coupling shaft and revolving meber, together turns round at transmitting movement and dynamic process natural axis and does not throw off.Joining shaft is connected with transmitting movement and torque with axle (sometimes also joining shaft and other rotary parts).Generally speaking, being joined the relativity shift that diaxon possibly occur has: a) axial dipole field b) radial deflection and c) angle skew and d) three kinds of combinations that skew occurs simultaneously squint.Impact spike load for the vibration, the reduction that reduce machine driven system, coupling also should have certain bumper and absorbing shock performance.
Current track adopts external gear to pass through taper hole with coupling more or spline is connected with output shaft with transmission shaft, uses special-shaped rubber parts sealing, carries out bolt the mentality of designing of closing through flange.It has the external tooth utilization awl of employing or spline is fixed on the axle, is inconvenient to dismantle; Ring gear has swing at the volley, easy and motor sidewall and the collision of speed reducer sidewall friction; Ring gear swing in the work, it is big to take up room; Special-shaped rubber parts is difficult for processing, and the cycle is long, is not easy shortcomings such as replacing.
Summary of the invention
It is a kind of for convenience detach and can realize the gear coupling of low-cost reliable sealing on rail vehicle, using the problem that runs in the coupling process with solving present reality that the purpose of the utility model provides to existing deficiency in the above-mentioned existing technology just.
The purpose of the utility model can realize through following technique measures:
The technological scheme that the gear coupling of the utility model adopts is: be connected internal gear with transmission shaft with straight pin through bolt; Connect and transmitting torque through end tooth between two external gears; Connect two ring gears through bellows, utilize the deformable of bellows to compensate the relative movement and the displacement of coupling; Connect two ring gears through bellows, form airtight cavity and play the seal action of coupling.
Specifically: the gear coupling of the utility model comprises the left and right end tooth gear that combines with the coaxial line mode through T-Ring, to be separately positioned on the tapered sleeve that is used to be connected line shaft and output shaft in the end tooth gear cavity of the left and right sides with left and right sides end tooth gear coaxial line mode; The outer end of said two tapered sleeves is equipped with a ring gear through link respectively, and two ring gears are meshed through interior external tooth with the end tooth gear of side respectively; Between two opposite ends of two ring gears, bellows component is installed, and constitutes sealed cavity jointly by bellows component and two ring gears.
The described ring gear of the utility model is through fillister head screw, fillister head screw and tapered sleeve Joint; The two ends of the described bellows component of the utility model combine with corresponding ring gear end face through seal joint respectively; Be processed with at the binding end of ring gear and bellows component and be used in sealed cavity, adding the lubricant oil through hole, this through hole seals through combination seal pad and hexagonal socket head plug.
The tapered sleeve of the described connection line shaft of the utility model is connected with line shaft through the conical surface or internal spline; Through transferring torque to two end tooth gears that are meshed with ring gear that the tapered sleeve that is connected line shaft combines; Two end tooth gears transfer torque to the ring gear that the tapered sleeve with being connected output shaft that is meshed combines, and transfer a torque to the output shaft that combines through the tapered sleeve that connects output shaft.
The gear coupling of the utility model is when line shaft and output shaft have relative movement, and ring gear and line shaft and output shaft are static relatively, and two end tooth gears are static relatively, between ring gear and end tooth gear, carry out relative slip and deflection.
The beneficial effect of the utility model is: two ring gears are static relatively with line shaft, output shaft respectively; The possibility that frictional impact appears in ring gear beat and motor sidewall or speed reducer sidewall can not take place; The coupling usage space is littler, more can satisfy harsh on-the-spot service condition; Need tapered sleeve not press-fited when carrying out situation such as coupling maintenance, maintenance at the scene, greatly reduce and safeguard on-the-spot labor intensity, improved working efficiency; Use bellows to connect the two ends ring gear and seal, make outside media such as impurity can't get into media such as inner lubricant oil of the inner coupling simultaneously of coupling or fat and also can't flow out, improved working life; Use bellows to connect the two ends ring gear and seal, utilize the resiliently deformable of bellows, making seal structural part not have relative movement does not have friction, has improved the working life of seal structural part, has prolonged maintenance period and has reduced maintenance cost; Use end tooth to connect transmitting torque, have the big characteristics of transmitting torque, cancelled the design of general coupling flange, the coupling outside dimension that reduces has reduced the volume of coupling, has further improved the application space of this coupling.
