Abstract
The utility model belongs to the field of an idle rod assembly and particularly relates to a fastening structure of a pin shaft of an idle rod. The fastening structure disclosed by the utility model comprises a cover plate and a shaft sleeve, wherein the shaft sleeve is internally provided with a countersunk head screw; the countersunk head screw is positioned and fixed together with upper and lower gaskets through locking screws; a butterfly-shaped spring is arranged between the lower gasket and the countersunk head screw; by utilizing the retraction function of the butterfly-shaped spring, the screw can be prevented from being loosened; and meanwhile, a gap reserved between the end face of the screw and the cover plate is reduced. A rubber spring is arranged between the lower gasket and the cover plate so as to buffer impact force between the countersunk head screw and the cover plate; and meanwhile, the fastening structure has a certain compensation function under the condition that the shaft sleeve is abraded.
Description
Technical field
The utility model belongs to idle rod assembly field, relates in particular to a kind of fastening structure of idle rod bearing pin.
Background technology
People are in order better to go on a tour now; Cross-country car can be selected by most of families, and the superior performance of cross-country car can overcome a lot of unfavorable road conditions; So the sales volume of cross-country car is increasingly high on the market now; Though but present cross-country car performance increases, from the situation that present batch entrucking is used, form allows of no optimist.Particularly from the failure phenomenon of inefficacy part, great majority are because flathead screw is loosening under the impact live load, cause the bearing pin pine spacious.Existing most of cross-country car has been coated with the happy safe high strength screw thread fastening glue of the U.S. on full stand of thread, the upper limit of as prescribed moment is tightened screw; But still loosening the inefficacy, this is a universal phenomenon, is not indivedual fortuitous phenomena; Travelled distance is few, and it is spacious pine just to occur, and consequence is very serious.
The utility model content
The utility model provides a kind of high lubricating effect, reduces each component wear, improves the idle rod bearing pin fastening structure in service life.
In order to solve the problems of the technologies described above; The utility model provides following technical scheme: idle rod bearing pin fastening structure; Comprise cover plate, axle sleeve, the flathead screw in the axle sleeve, flathead screw is through lock screw and upper and lower packing ring positioning and fixing; Be provided with belleville spring between described lower gasket and the flathead screw, be provided with rubber spring between lower gasket and the cover plate.
Adopt technique scheme, in the utility model, be provided with belleville spring between described lower gasket and the flathead screw; Utilize the shrinkage of belleville spring, prevent screw loosening, simultaneously; Reduce the gap of screw end face and cover plate; Be provided with rubber spring between lower gasket and the cover plate, the impulse force between buffering flathead screw and the cover plate can play a little compensating action simultaneously under axle sleeve worn-down situation.
Further, said axle sleeve is the steel axle sleeve of inner wall belt tin lead bronze alloy anti-attrition layer, and this axle sleeve is used in hanger that turns to intermediate rockers, loaded vehicle, steering column of loaded vehicle etc. to be had in the parts of impact load, low-speed motion; Nonabradable premium properties is arranged, simultaneously, when design, increase oil groove and oilhole at inwall; Increase the length of fit of axle sleeve, improve degree of lubrication, improve resistance to abrasion; Result of use is fine, and the early stage pine that solves original design is spacious, improves the life-span.
Further, belleville spring is the Q41214 model, meets operating needs.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model idle rod bearing pin fastening structure;
Fig. 2 is the structural representation that the utility model idle rod bearing pin fastening structure bottom bracket axle launches.
The specific embodiment
As shown in Figure 1: idle rod bearing pin fastening structure comprises cover plate 7, axle sleeve 1, the flathead screw 2 in the axle sleeve; Flathead screw 2 is provided with belleville spring 6 through lock screw 3 and upper gasket 4, lower gasket 5 positioning and fixing between described lower gasket 5 and the flathead screw 2, utilizes the shrinkage of belleville spring 6; Prevent that countersunk head spiral shell 2 nails are loosening, simultaneously, reduce the gap of flathead screw 2 end faces and cover plate 7; Be provided with rubber spring 8 between lower gasket 5 and the cover plate 7, described axle sleeve 1 is the steel axle sleeve of inner wall belt tin lead bronze alloy anti-attrition layer, and this axle sleeve 1 is used in hanger that turns to intermediate rockers, loaded vehicle, steering column of loaded vehicle etc. to be had in the parts of impact load, low-speed motion; Nonabradable premium properties is arranged, simultaneously, as shown in Figure 2: as when design, to increase oil groove 9 and oilhole 10 at inwall; Increase the length of fit of axle sleeve 1, improve degree of lubrication, improve resistance to abrasion; Result of use is fine, and the early stage pine that solves original design is spacious, improves the life-span.
Belleville spring 6 is the Q41214 model in addition, meets operating needs.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; Should be regarded as the protection domain of the utility model, these can not influence effect and practical applicability that the utility model is implemented yet.
