Abstract
The utility model is a roller positioning mechanism of roller type overdrive clutch, which is belong to the field of mechanical overdrive clutch and has the overdrive clutch mechanism of traditional roller-type; the utility model is characterized in that: the spring ejector-pin mechanism which presses the roller mechanism tightly in the overdrive clutch mechanism of the traditional roller-type is canceled, and one or more magnets which keeps certain distance with the roller axes are provided at the other side of the roller axes which corresponds with the spring ejector-pin in the overdrive clutch mechanism of the traditional roller-type. The utility model can position the roller on the next working position stably, avoids the wear of which the traditional spring ejector-pin gives to the roller, and prolongs the service life of overdrive clutch.
Description
One, technical field
The utility model is the roller positioning mechanism that belongs to a kind of roller-type overrunning clutch in mechanical free wheel device field.
Two, background technique
We know, in traditional roller-type overrunning clutch mechanism, the effect of spring knock pin mechanism holds out against roller all the time and is positioned on the working position, otherwise, free wheel device can't proper functioning, but, this mechanism also exists a problem simultaneously, be exactly in the working procedure of free wheel device, because the roller in the mechanism contacts all the time with ejector pin, so, certain wearing and tearing and heat will be produced, in addition, if ejector pin is inhomogeneous or pressure is not enough to the roller applied pressure, also may make roller on the working position, produce certain inclination, like this, will have a strong impact on the workmanship of mechanism, the serious damage that can directly influence the working life of clutch or cause clutch.For example, in some industry such as homemade loader industry, the problem in working life that is used for the roller-type overrunning clutch of fluid torque converter has become the difficult problem of an industry.
Three, model utility content
The purpose of this utility model be propose a kind of the active force of roller restriction tension on the working position is relatively large by magnetic force, can get rid of roller in the course of the work with the principle technological scheme of the roller positioning mechanism of a kind of roller-type overrunning clutch of the non-contact type of the rubbing action of traditional ejector pin.
The utility model is to realize like this, has traditional roller-type overrunning clutch mechanism in the mechanism, it is characterized in that: the spring knock pin mechanism that holds out against roller mechanism in the traditional roller-type overrunning clutch mechanism is removed, and the opposite side of the roller axis corresponding with former spring knock pin mechanism is installed the magnet that one or more and roller keep certain distance in traditional roller-type overrunning clutch mechanism star-wheel.When the star-wheel in the traditional roller-type overrunning clutch mechanism is out star wheel 4, magnet 2 can be made into rectangle or cylindrical, and is installed in and the opening surface that is shaped on vertically along the roller 3 axis another side corresponding with former spring knock pin mechanism in the work breach of roller 3 on ring 1 cylindrical in being placed on is housed on the out star wheel 4 its in roller 3 grooves.When the star-wheel in the traditional roller-type overrunning clutch mechanism is star-wheel 5, magnet 6 can be made into rectangle or cylindrical, and the opening surface that is shaped on vertically above the boss that the opposite side along corresponding star-wheel 5 working surfaces of roller 7 axis and former spring knock pin mechanism of the roller 7 be equipped with on the endoporus that is placed on outer shroud 8 and interior star 5 working surfaces is shaped on is installed within it in roller 7 grooves.During concrete work, because present permanent magnet is relatively large to the attraction force that roller produces, so can be more stable roller be positioned on the correct working position, and, owing to be that certain air clearance is arranged between magnet and the roller at this moment, so the service wear that can effectively avoid traditional spring knock pin mechanism that roller is caused, the so just working life of the free wheel device that effectively improves.
Owing to the utlity model has the active force of roller relatively large, can be more stable roller be positioned on the correct working position, can get rid of the service wear that roller causes with the rubbing action of traditional ejector pin in the course of the work, the characteristics such as working life of effective free wheel device that improves, so, can receive more positive effect after the enforcement.
Four, description of drawings
The utility model has 2 accompanying drawings, and Fig. 1 is that star-wheel is the roller positioning mechanism basic structure schematic representation of a kind of roller-type overrunning clutch of out star wheel, and Fig. 2 is that star-wheel is the roller positioning mechanism basic structure schematic representation of a kind of roller-type overrunning clutch of star-wheel.Among each figure: 1, interior ring, 2, magnet, 3, roller, 4, out star wheel, 5, star-wheel, 6, magnet, 7, roller, 8, outer shroud.
Five, embodiment
Below, in conjunction with Figure of description, the utility model is described in further detail.
In Fig. 1, generally speaking, magnet 2 can be directly installed on opening surface in the working position in roller 3 grooves, and install traditional cover plate to limit its axial motion just passable at the two ends of out star wheel 4, generally speaking, the most handy nonmagnetic substance of cover plate is made, favourable like this and the slip of roller 3 on working surface, because out star wheel 4 is steels, so what magnet 2 can be very firm is adsorbed in the groove, can not fall down in the course of the work, in case of necessity, can magnet 2 be fixed in the groove yet by the method for bonding or the method for mechanical fixation.Under possible condition, should make the axial clearance between magnet 2 and the roller 3 smaller as far as possible along roller 3.Certainly, the design in this gap should be considered the problem of the reasonable function power of effective wear extent of roller 3 and out star wheel 4 working surfaces and 2 pairs of rollers 3 of magnet simultaneously.
In Fig. 2, generally speaking, magnet 6 can be directly installed on star-wheel 5 working surfaces end relative with traditional spring knock pin installation position for roller 7 axis and be shaped on the upper opening surface that is shaped on of lug boss in the groove of roller 7, and install traditional cover plate to limit its axial motion just passable at the two ends of star-wheel 5, generally speaking, the most handy nonmagnetic substance of cover plate is made, favourable like this and the slip of roller 7 on working surface, reason is steels because of star-wheel 5, so what magnet 6 can be very firm is adsorbed in the groove, can not fall down in the course of the work, in case of necessity, also can magnet 6 be fixed in the groove by the method for bonding or the method for mechanical fixation.Under possible condition, should make the axial clearance between magnet 6 and the roller 7 smaller as far as possible along roller 7.Certainly, the design in this gap should be considered the problem of the reasonable function power of effective wear extent of roller 7 and star-wheel 5 working surfaces and 6 pairs of rollers 7 of magnet simultaneously.When magnet 6 was made cylindrical structural, can make on the direction vertical with roller 7 axial directions of the boss upper edge of star-wheel 5 generally was two flat blind hole, directly with just passable in the magnet cartridge hand-hole.Generally speaking, can be at the opposite side of star-wheel 5 boss grooves, be shaped on the inclined-plane that a centre hollows out, like this, since the magnet 6 of this group of rollers relatively with another group of rollers in the distance of roller 7 far away, the roller 7 that just can effectively limit in the group of rollers that is adjacent is come by 6 attractions of the magnet in this group of rollers.
