Description

Anti- axial high impact overload motor
Technical field
It the utility model is related to a kind of motor, more particularly to a kind of anti-axial high impact overload motor.
Background technology
The motor of traditional structure, when rotor is by axial impact force, the impact load suffered by it will be applied to master completely On bearing between axle both ends and casing, because bearing bears the limited in one's ability of axial force, it should be carried when impact load exceedes During ability, bearing will be damaged, and motor operation hydraulic performance decline even damages shutdown.Therefore, for being often subject to very big axle Just need to be improved the structure of existing motor to the motor of impact load, avoid bearing impaired and make motor can not normal work Make.
Utility model content
The utility model is in order to solve weak point of the prior art, there is provided one kind can bear high axial impact and bear Lotus, avoid the impaired anti-axial high impact overload motor of bearing.
In order to solve the above technical problems, the utility model adopts the following technical scheme that:Anti- axial high impact overload motor, bag Casing, rotating shaft, stator and rotor are included, stator is fixedly installed on the circumferential inner wall of casing, and the left and right ends portion of casing is provided with One bearing chamber, in each bearing chamber interference one bearing is installed, rotor is fixedly installed in rotating shaft, rotating shaft left and right ends It is each passed through the inner ring of a bearing and coordinates with bearing inner race gap, rotating shaft surface in axial direction offers twice difference position Guide groove on the inside of a bearing, the inner ring of each bearing are in axial direction fixedly connected with the guide block extending into guide groove, led The width of groove is equal with the width of guide block, and the axial length of guide groove is more than the axial length of guide block;Casing left part is in left side Left end cap is provided with outside bearing chamber, the left end of rotating shaft stretches out left end cap, and casing right part is provided with the right side outside the bearing chamber on right side End cap, right end cap axle portion offer through hole, coaxial on the right side of right end cap to be provided with outer cylinder body and inner barrel, outer cylinder body left end and interior Cylinder left end is fixedly connected by annular slab, and annular slab left-hand face is fixedly connected with right end cap right lateral surface, inner barrel right-hand member Closure plate is fixed with, annular housing is formed between outer cylinder body inwall and inner barrel outer wall, outer cylinder body right-hand member is fixedly connected with sealing Plate, sealing ring is provided between outer cylinder body right side and sealing plate left surface, inner barrel left side is open, the coaxial fixation of rotating shaft right-hand member Guide pillar is connected with, guide pillar is slidably connected in inner barrel, is provided with guide pillar and is slidingly sealed the close of cooperation with the inwall of inner barrel Seal, if uniformly offering capable person's annular housing and the oilhole connected inside inner barrel, the 1- of the internal diameter of oilhole on inner barrel 3mm, annular housing are less than the volume being more than inside inner barrel, hydraulic oil, hydraulic oil are filled with inner barrel and annular housing Volume be equal to inner barrel inside volume.
Jump ring is provided with rotating shaft, jump ring contacts with the right side of the bearing inner race on right side.
Inner barrel is internally provided with a compression spring, and the left end of compression spring is fixedly connected with the right-hand member of guide pillar, when When hydraulic oil no pressure and compression spring are in the fully extended state, the right part of compression spring contacts with closure plate, leads simultaneously The right part of block contacts with the right part of guide groove.
Using above-mentioned technical proposal, rotating shaft left end is clutch end, when rotating shaft left end is by axial impact, rotating shaft meeting Play to the right suddenly, the guide block that the guide groove in rotating shaft is fixedly installed along bearing inner race move right, and rotating shaft right-hand member will drive Guide pillar, guide pillar drive compression spring top pressure closure plate to the right, meanwhile, guide pillar produces thrust to hydraulic oil, by the hydraulic pressure in inner barrel Oil is squeezed into toroidal cavity by oilhole, and because guide pillar moves from left to right, the sealing ring on guide pillar can be by inner barrel Oilhole blocks, and oilhole passage reduces between inner barrel and annular housing, and the pressure increase of hydraulic oil in inner barrel, hydraulic oil is with regard to energy Good buffering decompression left and right is played, compression spring also functions to good cushioning effect, so it is avoided that bearing receives impulsive force, It is effectively protected bearing.The cooperation between the guide block being fixedly installed on guide groove and bearing inner race is opened up in rotating shaft to be used to transmit torsion Square, while be also convenient for rotating shaft and be axially moveable, under conditions of there is gap between rotating shaft and bearing inner race, also ensure that rotating shaft exists Friction is not produced in rotation process with bearing inner race.Jump ring is used for the effect for positioning right side bearing axial location.
When compression spring is in the fully extended state, the right part of compression spring contacts with right end cap, while guide block Right part contacts with the right part of guide groove;So when rotating shaft does not receive axial impact force, rotating shaft is set to position in the axial direction.
Annular housing is less than the volume being more than inside inner barrel, and the volume of hydraulic oil is equal to the volume inside inner barrel, After being full of hydraulic oil so in annular housing, still some hydraulic oil inside inner barrel, guide pillar is avoided by compression spring Very stiff and demanding stress is produced when being pressed onto the most short limit.
The utility model is played good anti-Axial Shock Load, compared using the double buffering guarantee of hydraulic pressure and spring Only set a compression spring to enter row buffering, make the motor that there is stronger anti-axial impact.
