Abstract
The invention discloses an axially inserted spring overrunning clutch. An elastic driver is disposed between every two peripherally adjacent rollers (2) and comprises two springs (1) in a splayed form; each spring (1) is composed of a corrugated segment (1a), a sinuous segment (1b) and a straight segment (1c); the corrugated segments (1a) of the springs (1) are axially inserted into fitting grooves correspondingly arranged in the inner wall of a body (5); the straight segment (1c) of one spring (1) of each elastic driver is abutted to the peripherally front one of the rollers (2), and the straight segment (1c) of the other spring (1) is abutted to the peripherally rear one of the rollers (2). The elastic drivers each comprising two axially inserted springs are used to drive the rollers, the springs are well positioned axially and radially, motion synchronousness of the rollers can be guaranteed, performance reliability of the axially inserted spring overrunning clutch can be improved, and the axially inserted spring overrunning clutch is longer in service life.
Description
Technical field
The present invention relates to a kind of one-way element, specifically, the particularly axial plug-in type free wheel device of a kind of reed.
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 the axial plug-in type free wheel device of reed that is simple, good reliability.
Technological scheme of the present invention is as follows: the axial plug-in type free wheel device of a kind of reed, 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 the reed (1) of two pieces of distributions in "eight" shape, described reed (1) is by waveform section (1a), roundabout section (1b) and straight section (1c) form, waveform section (1a) is connected with straight section (1c) by roundabout section (1b), the waveform section (1a) of each reed (1) is inserted in the adaptive groove that on body (5) inwall, correspondence is offered vertically, the straight section (1c) of elastic drive part wherein one piece of reed (1) abuts with circumferentially previous roller (2), and the straight section (1c) of another block reed (1) abuts with a circumferentially rear roller (2).
The present invention adopts the elastic drive part of one group of reed composition to substitute stage clip and move to drive roller, and reed is made up of waveform section, roundabout section and straight section, and moulding simply, is easy to processing and fabricating; The waveform section of reed is inserted in the adaptive groove of body vertically, easy for installation, quick, and reed radial direction is located by waveform section, axially by baffle plate and guard shield spacing, reed location is reliable, can not occur to loosen or come off.Straight section with piece reed of two in group abuts with circumferentially former and later two rollers all the time, 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.By roundabout section of transition between the straight section of reed and waveform section, under the effect of roundabout section, straight section has enough elastic force, roller is moved faster.
Conveniently selection, is convenient to processing and fabricating, and reduce cost of production, and guarantee there is enough elastic force, described reed (1) is made up of spring steel.
As preferably, 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.
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.

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 elastic drive part, 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 elastic drive part, elastic drive part is circumferentially uniformly distributed.Two pieces of reeds 1 that described elastic drive part is distributed by "eight" shape form, and reed 1 is formed by waveform section 1a, roundabout section of 1b and straight section 1c, and is made up of spring steel, and the waveform section 1a of reed 1 is connected with straight section 1c by roundabout section of 1b.The waveform section 1a of each reed 1 inserts on body 5 inwall in the corresponding adaptive groove offered vertically, and reed 1 radial direction locate by waveform section 1a, axis by baffle plate 3 and guard shield 4 spacing.With in group wherein the straight section 1c of one piece of reed 1 abut with circumferentially previous roller 2, the straight section 1c of another block reed 1 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.
