Description
Technical field
The utility model relates to a kind of one-way element, specifically, and particularly a kind of mono-directional overrun engaging and disengaging gear.
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.
Model utility content
Technical problem to be solved in the utility model is that providing a kind of assembles mono-directional overrun engaging and disengaging gear that is simple, good reliability.
The technical solution of the utility model is as follows: a kind of mono-directional overrun engaging and disengaging gear, 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 combined type reed (1), this combined type reed (1) is by cylindrical body (1a), first reed (1b) and the second reed (1c) composition, described cylindrical body (1a) inserts in body (5) the adaptive groove that above correspondence is offered vertically, and by the closing in of adaptive groove, baffle plate (3) and guard shield (4) jointly spacing, described first reed (1b) is fixed (1a) with the root of the second reed (1c) and is connected with cylindrical body, there is between first reed (1b) and the second reed (1c) angle of 20-30 °, described first reed (1b) abuts with circumferentially previous roller (2), second reed (1c) abuts with a circumferentially rear roller (2), 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 utility model adopts combined type reed to substitute stage clip and moves to drive roller, and the moulding of combined type reed is simple, is easy to processing and fabricating; The cylindrical body of combined type reed inserts in the adaptive groove of body vertically, easy for installation, quick, and the radial and circumference of combined type reed is positioned by cylindrical body, axially by baffle plate and guard shield spacing, combined type reed location is reliable, can not occur to loosen or come off.Two pieces of reeds abut with circumferentially former and later two rollers all the time, and promote roller by the tension force between two reeds and 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.
The number of described roller (2) is 6-16.Because the assembling of combined type reed 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 utility model drives roller by combined type reed, compact structure, processing and assembling are easily, cost of production is low, reed location is 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.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.
