Abstract
The utility model relates to a stop washer which is used between a screw bolt and a nut in mechanical fastening members. Two parts of a shearing washer and a fixing washer are superposed to form the stop washer which is used between a screw bolt and a nut in mechanical fastening members. More than two fixing pins which are embedded on the surfaces of fastened members, and more than two braking pin holes for embedding braking pins are arranged on the fixing washer. More than two braking pins are arranged on the shearing washer, and more than two unidirectional braking sheets are punched on the shearing washer. Braking grooves whose positions are corresponding to the positions of the unidirectional braking sheets are arranged on a nut. The stop washer which is used between a screw bolt and a nut in mechanical fastening members has the advantages that the stop washer which is used between a screw bolt and a nut in mechanical fastening members is firm and reliable; the stop washer which is used between a screw bolt and a nut in mechanical fastening members is convenient to operate when the stop washer which is used between a screw bolt and a nut in mechanical fastening members is installed and disassembled; the stop washer which is used between a screw bolt and a nut in mechanical fastening members can be used for a plurality of times.
Description
The utility model relates to mechanical engineering, is in the machanical fastener, a kind of lock washer that is suitable between the bolt nut.
At present in the mechanical engineering, loosening for preventing nut, multiple lock washer has appearred, and as the lock washer with tongue at outside of GB856-88 regulation etc., this class lock washer is only expendable consumable accessories, and is not suitable for locking strict scyewed joint place.
The purpose of this utility model provides a kind of lock washer, and it can be for repeatedly using repeatedly, and is easy and simple to handle during installation and removal, has enough reliabilities that the scyewed joint of preventing gets loose.
The purpose of this utility model is achieved in that lock washer by shearing packing ring and retaining washer two-part are stacked constitutes, and retaining washer is provided with the fixing pin and the plural braking pin-and-hole that embeds for shotpin on plural embedding fastener surface; The shearing packing ring is provided with plural shotpin and punching out has plural unilateral system moving plate; Nut is provided with the position breaker slot corresponding with the unilateral system moving plate.
Before using lock washer of the present utility model, need around the bolt of fastener, to be provided with the fixed pin holes corresponding with the fixing pin position.During use, as long as lock washer is placed on the bolt, and pin is inserted in separately the hole, load onto nut then and screw.At this moment, fastener, bolt, nut, lock washer consist of an integral body by fixing pin, shotpin, unilateral system moving plate, have to prevent that nut is because of the loosening function of environmental vibration derotation.When needs are dismantled, only need the shotpin of shearing on the packing ring to be cut off with a bigger reverse turn nut of moment, just can dismantle.If need reuse, as long as the shotpin of changing.
The characteristics of lock washer of the present utility model are: easy to operate during fastening reliable, installation and removal, can be for repeatedly use.
Embodiment further describes below in conjunction with accompanying drawing:
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-nut 2-shears packing ring 3-retaining washer 4-bolt 5-braking pin-and-hole 6-fixing pin 7-shotpin 8-unilateral system moving plate 9-breaker slot
Embodiment: the lock washer with M12 nut and bolt adapted is an example, and referring to accompanying drawing, the interior external diameter of packing ring is all selected by the GB97.2-85 standard, and packing ring all is to be processed into the 65Mn plate stamping.Shotpin, fixing pin and unilateral system moving plate are three and even the layout.Shearing packing ring thick is 1.4MM, the long 4MM of the wide 2.2MM of unilateral system moving plate that its upper punch is made, and high 1MM, punching and shotpin that shotpin is installed are drive fit.Retaining washer is thick to be 2MM, and the punching and the fixing pin that install and fix pin are drive fit, and braking pin-and-hole and shotpin are loose fit.Shotpin ABS material, diameter are the long 3.4MM of 2.4MM, and fixing pin 65Mn material, diameter are the long 5MM of 2.4MM.The lock washer of present embodiment can guarantee that nut remains on restraint location when unclamping torque less than 18 Newton meters.If the shotpin material adopts duralumin LY12 material, in the time of then can guaranteeing to unclamp torque less than 80 Newton meters, nut remains on restraint location.
Under the operating conditions of common anti-loose structure, generally have only less oppositely the unscrewing moment or do not have at all on the nut that act on.Under this type of condition, the utility model can guarantee locking permanent, has greatlyyer when oppositely unscrewing moment on acting on nut, for guaranteeing locking reliability and being convenient to dismounting, needs to use the heavy anti-loose structure of this anti-loose method; Having very under strong motion or the impact condition, needing to use antidetonation type anti-loose structure.These two kinds of anti-loose structures belong to of the present utility model development-oriented, and are irrelevant with the utility model, no longer dwell on.
