Description
Technical field
The present invention relates to a kind of electrical equipment, more specifically, it relates to a kind of elevator traction machine.
Background technology
Traction machine is the power supplying apparatus of motor lifting, lift car can be driven to move up and down, it is ensured that elevator functions
Realization.Present traction machine is all mostly to carry out producing power, the stator on traction machine to be fixed on using the structure of motor
Above the fixed structures such as metope, the coil after energization on stator drives the magnetic links above rotor to move using galvanomagnetic-effect,
So as to the positive and negative rotation of rotor driven.
Had in relative motion, therefore rotor a rotating shaft due to existing between rotor and stator, rotor can be with rotating shaft
Axis rotates, therefore can be arranged with bearing above rotating shaft and rotor, the stable rotation for realizing rotor.
Rotating shaft is installed in stator by without sealed bearings and rear bearing, and oil inlet passage would generally be provided with stator, its with
Oil pocket without sealed bearings is connected, and oil drain passage is connected with the oil pocket without sealed bearings, and plug cock is provided with oil drain passage, oil
Plug could only be opened when traction machine is shut down, and plug cock must keep the closure to oil drain passage under traction machine working condition.
Lipid lubricant is extruded toward open-type bearing oil pocket by oil inlet passage.If lubricant is contaminated when needing to change, only stop
Machine opens plug cock and can just discharge lipid lubricant.
In the middle of actually used process, user is past sometimes clamp-ons during compared with many greases of sauce without sealed bearings oil pocket, because heat expansion is cold
Contracting, the oil pocket without sealed bearings will not contain grease, in the operation process after a part of grease fluidization or aerification, lead
Cause oily cavity pressure increase, when greatly to certain numerical value, relative weak spot of the closing without sealed bearings oil circuit must be found, then
Oil leak pressure release, causes elevator that accident occurs.
And in-line, two pipelines of outlet line are separated, and generally two openings are had on stator, carry out different behaviour
Make, so comparatively cause the passage opened up in stator excessive, it is impossible to accomplish to simplify.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of elevator traction machine, by original oil-feed
Pipe is merged into an opening with two openings of oil discharge pipe, reduces open amount, while can be automatic by oil using pressure relief mechanism
Pressure inside chamber is laid down with waste gas waste oil.
To achieve the above object, the invention provides following technical scheme：A kind of elevator traction machine, including rotor and outer
The stator that boundary is fixed, the rotor includes the traction sheave that is wholely set, is equipped with rotating shaft on the rotor, the rotating shaft with it is described
Rear sealed bearings are provided between stator, open-type bearing, the open-type bearing are provided between the rotor and the stator
Both sides the first passage of connection open-type bearing oil pocket and the external world is opened, in institute's first passage by oil sealing sealing on the stator
The check valve that fuel feeding fat injects oil pocket is provided with, second channel is additionally provided with the stator, one end of the second channel is close with non-
Envelope bearing oil pocket connection, the other end is connected with first passage, and the opening that the first passage is in communication with the outside is located at stator inner side
And opening inwall is provided with internal thread, and pressure relief mechanism has been connected through a screw thread on the opening that first passage is in communication with the outside.
The present invention is further arranged to：The pressure relief mechanism includes hollow sleeve, and the sleeve is threadedly secured to
On first passage inwall, the sliding block slided along sleeve lining is provided with the sleeve, the sliding block is matched somebody with somebody with the inner wall sealing of sleeve
Close, the back-moving spring for driving sliding block to reset is connected with the sliding block, pressure relief opening is offered on the sleeve, the pressure relief opening connects
The oil-collecting part for reclaiming fluid is connected to, the position of the pressure relief opening meets following condition：It is sliding in the case that sliding block is not stressed
The location of block seals pressure relief opening.
The present invention is further arranged to：The oil-collecting part includes oil storage barrel, and oil storage barrel is provided with steam vent, connecting tube, institute
State connecting tube connection pressure relief opening and oil storage barrel.
The present invention is further arranged to：The connecting tube is connected with pressure relief opening inwall by pagoda joint.
The present invention is further arranged to：Adjustable plate is additionally provided with the sleeve, regulation screw mandrel, institute are equipped with the sleeve
Regulation screw mandrel one end is stated be connected with the adjustable plate, the other end outside the sleeve, described back-moving spring one end and the adjustable plate
It is fixedly connected, the other end is fixedly connected with a slide block.
Compared with prior art, it is an advantage of the current invention that original is thought into oil inlet pipe is merged into two openings of oil discharge pipe
One opening, when usual elevator traction machine is used, the position of opening is all to add the pressure relief mechanism for pressure release, and is waited
When needing to add lubricating oil, it is only necessary to disassemble pressure relief mechanism, oil nozzle is selected into lubricating oil again by screw thread
Oil pocket is injected by first passage.By the design of pressure relief mechanism, when oil pocket internal pressure can be worked as reaching certain, sliding block
Displacement is larger, and pressure relief opening is exposed, and so vaporization, liquefied fluid are just suffered with pressure relief opening into oil-collecting part, complete to let out
After pressure, sliding block can return block pressure relief opening, prevent introduced contaminants from entering oil pocket.
