Embodiment
Technological scheme of the present invention is on the architecture basics of free wheel device, guarantee its function, reasonably, utilize fully the major part of free wheel device, adopt one multiplex, introduce in addition the principle that limit is turned round the friction cushioning mechanism in the device structure, the on a small quantity necessary parts peculiar of increase, the invention design has the function of free wheel device, has concurrently again to limit novel structure, the multifunctional novel driving component-limit of the function of turning round device to turn round free wheel device.
It is core that limit of the present invention is turned round wedging part in the overrun clutch structure, combined friction pair, torque adjustment and release function thereof etc.The wedging part is the critical component of free wheel device, according to the working condition of its technical requirements, function and use, can design and select wedge block type or roller type, the performance features.The outer shroud of clutch is a multi-purpose function, not only forms the raceway of rotation wedging part in the clutch with interior ring, and as an element of friction mechanism with the flange platen with support external member composition friction pair.And be different from common free wheel device and directly be fixed on the support by key or bolt, without any rigid joint, but the frictional force of outer ring both ends of the surface connects with support or its driving component by the flange platen.Torque adjustment is by adjusting bolt and is adjusted in the default limit value scope, implements with digital display spanner or other afterburning method.By discharging bolt the dish spring is applied moment of torsion greater than limit value, implement release function.
The principle that limit of the present invention is turned round free wheel device is: limit the internal diameter of the outer shroud (6) of free wheel device in the composition of turning round free wheel device and the external diameter of interior ring (1) to consist of raceway placement wedging part, and interior edge face and the friction plate (7) of the both ends of the surface of outer shroud (6) and flange platen (8), supporting sleeve (10) be paired into friction pair, by adjusting bolt (12) and cylinder stage clip (11) frictional force that friction plate (7) applies is connected it.Leave the gap between the cylindrical of outer shroud (6) and supporting sleeve (10) respective interior bores simultaneously, regulate the cylinder stage clip by adjusting bolt (12) and add to the friction plate end force, the torque adjustment that free wheel device can be born is in a certain default limit value scope.
Turn round free wheel device when limit and be connected in the transmission system by the flange platen, drive running by motor or speed reducer shaft extension.As because stopping; overload; the burst accidents such as serious impact; limit is turned round free wheel device and is wanted to enter non-return state; if the moment of torsion that free wheel device at this moment wherein bears is during greater than the free wheel device limit value; outer shroud will overcome the friction torque between itself and the friction plate; and and fixed flange platen and supporting sleeve between produce relative sliding and throw off; to unload to other device of main frame above the part moment of torsion of limit value and share (such as many drivings); thereby avoid the peak value undue concentration of whole main frame check moment of torsion to turn round on free wheel device or other driving components a certain limit, protected limit to turn round the transmission device safety of free wheel device.Along with growth service time of free wheel device, friction pair can be worn, and at this moment the cylinder stage clip can give an amount of compensation, and its bearing capacity is still remained in the limit value scope.If but when wear extent was increased to certain value, the moment of torsion that free wheel device bears dropped to less than a certain limit value of regulation, will affect limit and turn round free wheel device normal operation reliability, even can't work.Therefore, make regular check on, measure, tighten adjusting bolt, regulate friction pressure, make limit turn round moment of torsion that free wheel device bears still in the limit value scope.
In addition, this limit is turned round free wheel device and also is provided with moment of torsion release function mechanism, discharges bolt (17), supporting sleeve (10), dish spring (20) and end cap (16) by 3 and forms.
Fig. 1 .a is that limit is turned round the overrun clutch structure plan view, and Fig. 1 .b to be limit turn round the overrun clutch structure side-looking and partly cut open figure.Express among the figure this limit turn round free wheel device by special over running clutch and limit turn round friction mechanism cleverly, compact, rational Combination Design implementer case.That limit of the present invention is turned round clear, the complete structural drawing of free wheel device.Described limit is turned round the overdrive clutch implement body and is comprised interior ring (1), wedging part (2), packing ring (3), axle bumper (4), Sealing (5), outer shroud (6), friction plate (7), flange platen (8), supporting sleeve (10), seal ring (9), cylinder stage clip (11), adjusting bolt (12), end cap (13), protecting cover (16), discharge bolt (17), pad (19), dish spring (20), screw (15) and latch (14), wherein, described outer shroud (6) is not directly to be fixed on the support (frame), and with support without rigid joint is arranged, outer shroud both ends of the surface and flange platen (8) and supporting sleeve (10) load by adjusting bolt and cylinder stage clip by friction plate it are connected, change the pressure size that adds on the friction plate with adjusting bolt, limit is turned round torque adjusting that free wheel device bears to being limited in a certain limit value scope, and available torque spanner with digital display loads and reads numerical value.
Wherein, leave certain gap between the endoporus of the cylindrical of described outer shroud and supporting sleeve.What described friction plate was used is asbestos-free friction material, has good wear resistance, and suitable and stable friction factor, the friction factor of the described middle employing of this programme are 0.34.
In Fig. 2 .a, interior ring (1), wedging part (voussoir, roller, spring etc.) (2), outer shroud (6), packing ring (3), axle bumper (4), Sealing (5) etc. form the free wheel device unit.Require to manufacture and design to become contact-type or non-contact wedge block and roller-type overrunning clutch according to the working condition that uses, its structure and working principle are same as special over running clutch.But the outer shroud of free wheel device of the present invention is not fixing by key or bolt and stand stiffness, outer shroud then is by the pressure of adjustable friction mechanism for implementing to friction plate, frictionally connects with support or other driving components through the flange platen, realizes its function.Outer shroud is that limit is turned round the common elements that free wheel device in the free wheel device and adjustable limit are turned round friction mechanism.
In Fig. 2 .b, outer shroud (6), friction plate (7), flange platen (8), seal ring (9), supporting sleeve (10), cylinder stage clip (11), adjusting bolt (12), end cap (13), latch (14) etc. form the adjustable friction damping mechanism, and side end of flange platen (8) end face and supporting sleeve is connected by adjusting bolt, cylinder stage clip with the end face of outer shroud (6) by the frictional force of friction plate (7).Simultaneously, leave the gap between the cylindrical of outer shroud and the respective interior bores of supporting sleeve, regulate the pressure that is added in the friction plate end face by adjusting bolt, can change the size of frictional force, be limited in a certain limit value thereby limit can be turned round the moment of torsion adjustment that free wheel device bears.
Simultaneously, in Fig. 2 .b, also express the moment of torsion releasing mechanism, form by discharging bolt (17), supporting sleeve (10), pad (19), dish spring (20), end cap (13) and latch.When the needs release function, the at first loosening bolt that discharges, pull up the latch that is inserted on the end cap on the supporting sleeve, then clockwise end cap is rotated a angle along the center circle of bolt hole, at this moment discharging bolt enters in the end cap large through-hole, tighten the release bolt, limit is turned round the release function of free wheel device and has just been started working.
When now limit being turned round clutch designs in the free wheel device and being non-contact wedge formula free wheel device, its working principle is carried out following explanation: the interior ring that limit is turned round free wheel device adopts key to connect with the high speed shaft extension of transmission system main frame, and outer shroud is to lean on the bolt hole of its friction mechanism by the flange platen to link to each other with support or other driving components to place among the transmission system.When host-initiated, ring and voussoir assembling (wedging part) rotation can produce centrifugal force during rotation in driving, and the trend that forces voussoir assembling and outer shroud to disengage is arranged.But the centrifugal moment that produces when its rotation also is not enough to overcome Returnning spring when imposing on the torque of voussoir, at this moment voussoir and interior ring working surface are in contact with one another, and produce the relative sliding friction with outer shroud, when interior ring rotating speed improves gradually, and when being equal to or greater than the minimum non-contact rotating speed of this clutch, at this moment the centrifugal moment that produces is equal to or greater than torque that Returnning spring adds in advance and the matter moment of voussoir, force like this voussoir in supported hole, to be offset and disengage with outer shroud, realization non-contact running, without friction, without wearing and tearing, reduce heating, improve working life.This time limit is turned round free wheel device and moves normally; but; when stop, have a power failure suddenly or mechanical failure etc. caused serious overload or impacted generation; at this moment outer shroud skids in transmission and automatically throws off; simultaneously, wedge system in the free wheel device (wedging part) also loses the wedging function, therefore; limit is turned round free wheel device and is in the effect that loses transferring power and motion, plays the effect of the whole transmission system driving component safety of protection.When transmission system recover gradually to turn round, when moment of torsion is reduced to default a certain limit value, limit is turned round free wheel device and is recovered again normal function.
Shown in Figure 3 being limited, turned round free wheel device job applications signal on two rotating band conveyors.Layout among Fig. 3 is that motor (3-1,3-7), limit are turned round free wheel device (3-2,3-5), speed reducer (3-3,3-6) and conveyor (3-4).General conveyor must be arranged free wheel device, to prevent that conveyor from stopping and to cause the reversing runaway accident when the serious overload of generation such as mechanical failure or impact.Simultaneously again because each free wheel device element is made, the different impact of installation and operation state of wear, under non-return state, the check moment unbalance that each free wheel device bears, so all braking moments can take the lead in acting on one of them.Now when the limit of using band limit square function is turned round free wheel device, as the free wheel device that takes the lead in bearing braking moment then can skid and automatically throw off, until at this moment other free wheel devicees work brake check moment by all free wheel device shareds.Effectively avoid Peak torque to the damage of system, the impact of also well protecting free wheel device itself not overloaded simultaneously.
Limit of the present invention is turned round free wheel device and is applicable to have broad application prospects in the mechanical transmission such as Belt Conveyors, metallurgical machinery, mining machinery, petrochemical machinery, printing machinery, lathe, speed reducer, gen-set and war products.
More than limit provided by the present invention turned round free wheel device be described in detail, used concrete indivedual example herein principle of the present invention and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
