Abstract
The invention discloses a composite reed type unidirectional overrunning clutch device which comprises a main body (5), a protective cover (4), a baffle (3) and rollers (2), wherein the protective cover (4) is mounted on one side of the main body (5), the baffle (3) is mounted on the other side of the main body (5); wedge-shaped positioning grooves uniformly and circumferentially distributed are formed in the inner wall of the main body (5); the rollers (2) are mounted in the wedge-shaped positioning grooves, and a composite reed (1) is arranged between the two adjacent rollers (2) on the circumference and is composed of a cylinder (1a), a first reed (1b) and a second reed (1c). The composite reed type unidirectional overrunning clutch device has the benefits that the rollers are driven by the composite reeds, the structure is compact, the processing and the assembly are easy, the production cost is low, the reed positioning is good, and not only can the motion synchronicity of all the rollers be ensured, but also the performance reliability of an overrunning clutch can be improved, so that the service life of the overrunning clutch is longer.
Description
Technical field
The present invention relates to a kind of one-way element, specifically, particularly a kind of composite spring chip 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.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of assembles composite spring chip mono-directional overrun engaging and disengaging gear that is simple, good reliability.
Technological scheme of the present invention is as follows: a kind of composite spring chip 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).
The present invention 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 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.
Beneficial effect: the present invention 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.

Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1 and Figure 2, the present invention is made up of parts such as combined type reed 1, roller 2, baffle plate 3, guard shield 4 and bodies 5.Wherein, body 5 is circle structure, installs guard shield 4 in the side of body 5, and opposite side installs baffle plate 3, and baffle plate 3 and guard shield 4 all fix with body 5.The inwall of body 5 offers circumferentially equally distributed wedge shape locating slot, and the number of wedge shape locating slot is 6-16, and the present embodiment is preferably 12.In each wedge shape locating slot, roller 2 is all housed, the shaft axis of roller 2 and the axis parallel of body 5.Roller 2 by baffle plate 3 and guard shield 4 spacing, roller 2 can only circumferentially moved.
As shown in Figure 1, Figure 3, between two circumferentially adjacent rollers 2, be provided with combined type reed 1, this combined type reed 1 is circumferentially uniformly distributed.Described combined type reed 1 is made up of cylindrical body 1a, the first reed 1b and the second reed 1c, and cylindrical body 1a to insert on body 5 in the corresponding adaptive groove offered vertically, and jointly spacing by the closing in of adaptive groove, baffle plate 3 and guard shield 4.First reed 1b fixes 1a with the root of the second reed 1c with cylindrical body and is connected, and has the angle of 20-30 ° between the first reed 1b and the second reed 1c.First reed 1b abuts with circumferentially previous roller 2, and the second reed 1c abuts with a circumferentially rear roller 2.Working principle of the present invention is same as the prior art, and therefore not to repeat here.
