Abstract
The invention provides a tooth-type shaft coupler which is characterized by comprising a left end tooth gear and a right end tooth gear which are combined together through a connecting ring in a coaxial way, and taper sleeves which are respectively arranged in concave cavities of the two end tooth gears in a way that the taper sleeves are coaxial with the left end tooth gear and the right end tooth gear are used for connecting a power shaft with an output shaft; an inner gear ring is arranged at each one of the two ends of the two taper sleeves through a connecting piece; and the two inner gear rings are respectively engaged with the end tooth gears at the corresponding sides though inner teeth and outer teeth; and two opposite ends of the two inner gear rings are provided with sealing rings through adjustable type sealing connecting pieces respectively; and the sealing rings can slide on external cylindrical surfaces of the end tooth gears 4 to play a sealing effect.
Description
Technical field
The present invention relates to a kind of gear coupling, mainly be used in industries such as rail vehicle.It connects to come transmitting torque through crowned teeth and end tooth; Make left and right sides half-coupling form sealed cavity respectively through associated seal (like " O " RunddichtringO, reinforced seal ring etc.), and carry out the coupling of selflubricating through the lubricant grease in the Seal cage.
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 (or axle 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.
Coupling such as current track vehicle adopt external gear to pass through taper hole more or spline is connected with output shaft with transmission shaft, use special-shaped rubber parts sealing, carry 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
The object of the invention provides a kind of for convenience detach and gear coupling that can low-cost reliable sealing just to existing deficiency in the above-mentioned existing technology, on rail vehicle, use the problem that runs in the coupling process with solving present reality.
The object of the invention can be realized through following technique measures:
The present invention realizes that the technological scheme that above-mentioned coupling 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; External cylindrical surface through external gear cooperates with " O " RunddichtringO and plays seal action; And the move seal of assurance coupling inner chamber when guaranteeing that line shaft and output shaft have relative displacement of the adjustment ring through fixing " O " RunddichtringO.
Specifically: gear coupling of the present invention comprises the left and right end tooth gear that combines with the coaxial line mode through T-Ring, to be separately positioned on two tapered sleeves that are used to be connected line shaft and output shaft in the end tooth gear cavity with left and right 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; Be separately installed with the seal ring that seals that the external cylindrical surface with the end tooth gear slides in two opposite ends of two ring gears through the regulating type seal connector.
Ring gear of the present invention is through fillister head screw, fillister head screw and tapered sleeve Joint; Described regulating type seal connector is formed by adding the adjustment ring that is held between gland and the baffle ring; Said seal ring is the O RunddichtringO, and this O RunddichtringO is installed in the end of adjustment ring, and forms the sealing means that is slidingly matched with the external cylindrical surface of end tooth gear 4.
The tapered sleeve of connection line shaft of the present invention 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.
Gear coupling of the present invention 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 invention has the beneficial effects as follows: ring gear and line shaft and output shaft are static relatively, and the possibility that frictional impact appears in ring gear beat and motor sidewall or speed reducer sidewall can not take place, and 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 industry modal " O " RunddichtringO seals rather than adopts other special-shaped sealing configurations, has reduced the manufacturing cost of product, has improved the versatility of product maintenance; 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.
