Description
Technical field
The present invention relates to a kind of one-way element, specifically, particularly a kind of roller-type overrunning clutch.
Background technique
Free wheel device is the basic part occurred along with the development of electromechanical integrated product, and it is the vitals for transmission of power and separation function between prime mover and working machine or between machine intimate driving shaft and driven shaft.The major function of free wheel device is: surmount or transmitting torque, accurately locate, prevent reverse.
Existing free wheel device is generally made up of body, guard shield, baffle plate, roller and stage clip.Roller is arranged in the wedge shape locating slot that inner body wall is offered, by guard shield and baffle plate axial limiting.In wedge shape locating slot, be also provided with stage clip, a corresponding roller of stage clip, stage clip drives roller to move in wedge shape locating slot.Because stage clip needs processing skewed slot in addition to install, the difficulty of processing of stage clip installation skewed slot is large on the one hand, can increase cost of production; On the other hand, stage clip assembling difficulty, easily produces crooked, causes stage clip clamping stagnation, fracture, thus affect reliability and the working life of free wheel device.In addition, guard shield is generally fixed by screw and body, and not only dismounting is inconvenient, and the tightness engaged between guard shield with body is poor, and guard shield easily loosens and produces abnormal sound.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of firm, reliable roller-type overrunning clutch.
Technological scheme of the present invention is as follows: a kind of roller-type overrunning clutch, comprise body (5), guard shield (4), baffle plate (3) and roller (2), in the side of described body (5), guard shield (4) is installed, opposite side installs baffle plate (3), the inwall of body (5) is provided with circumferentially equally distributed wedge shape locating slot, roller (2) is all housed in each wedge shape locating slot, it is characterized in that: between two circumferentially adjacent rollers (2), be provided with elastic drive part, this elastic drive part is circumferentially uniformly distributed, described elastic drive part has two pieces of reeds (1), described reed (1) is " L " type, by orthogonal galianconism with long-armedly to form, the galianconism of each reed (1) and part is long-armed to insert on body (5) inwall in the corresponding adaptive groove offered vertically, long-armed and the circumferentially previous roller (2) of elastic drive part wherein one piece of reed (1) abuts, and the long-armed and circumferentially rear roller (2) of another block reed (1) abuts, all sides of described body (5) are ledge structure, by middle cone section transition between the large section of body (5) all sides and segment, described guard shield (4) is made up of end (4a), ring portion (4b) and kink (4c), the end (4a) of guard shield (4) and the end face of body (5) are close to, the ring portion (4b) of guard shield (4) is by coated for the large section of body (5) all sides, the kink (4c) of guard shield (4) is formed to in-flanges by the free end of ring portion (4b), and this kink (4c) is coated in the cone section in the middle of all sides of body (5).
The present invention adopts the elastic drive part of one group of L-type reed composition to substitute stage clip and moves to drive roller, and reed moulding is simple, is easy to processing and fabricating; The galianconism of reed and part is long-armed inserts in the adaptive groove of body vertically, easy for installation, quick, reed radial direction is located by galianconism, axially by baffle plate and guard shield spacing, reed location is reliable, can not occur to loosen or come off.All the time abut with circumferentially former and later two rollers with the long-armed of piece reed of two in group, promote roller by the tension force between two reeds to move in wedge shape locating slot, so circumferentially the synchronism of each roller motion is good, and free wheel device reliable performance, working life is secure.
The end of guard shield and the end face of body are close to, the large section of the ring portion of guard shield and all sides of body is close to, and the cone section of the kink of guard shield and centre, body week side is close to, and guard shield is fixed by rolling and body, not only be easy to assembling, packaging efficiency is high, and guard shield and body engagement are tight, has connected not only firmly but also reliable, the end of guard shield coordinates with kink, also play the left and right of axially locating, effectively can prevent guard shield from occurring to loosen, eliminate because guard shield loosens the disadvantage producing abnormal sound.
Conveniently selection, is convenient to processing and fabricating, and reduce cost of production, and guarantee there is enough elastic force, described reed (1) is stamped to form by spring steel sheet material.
The number of described roller (2) is 6-16.Because reed assembling is simple, arranges easily, such body can be arranged the roller of greater number, effectively to improve bearing capacity.
Described guard shield (4) is steel stamping part, has the angle of 130-140 degree between the ring portion (4b) of guard shield (4) and kink (4c).Such one side processing and fabricating is easy, is conducive to batch production; On the other hand, shroud structure intensity is good, can not deform or damage.
Described baffle plate (3) is steel circular arc flat board, and by circumferentially equally distributed screw and body (5) fix.Above structural baffles selection is convenient, is easy to produce and assembling, and baffle plate and body contacts area are greatly, are connected firmly, reliably.
Beneficial effect: the present invention forms elastic drive part to drive roller by the reed of two pieces of axial plug-in mountings, compact structure, processing and assembling easily, low, the reed axis of cost of production and radial location good, the synchronism that each roller moves can not only be ensured, and the reliability of free wheel device performance can be improved, make the longer service life of free wheel device, have design ingenious, be easy to the features such as transformation.Meanwhile, guard shield adopts folded-edge mounting structure, and easy for installation, quick on the one hand, packaging efficiency is high; On the other hand, closely, fixing is good for guard shield and body engagement, can not occur to loosen or come off.
