Abstract
The invention discloses a wrong assembly prevention assembly structure for a crankshaft thrust shoe. The assembly structure comprises a bearing pedestal and a thrust shoe, wherein, one side of the bearing pedestal is provided with an installation face, the thrust shoe comprises a first end face and a steel back side which are adjacently connected, wherein, the steel back side is attached to the installation face, a part of the first end face, which is adjacent to the steel back side, is provided with a bulge, and a positioning groove is arranged on the installation face and is matched with the bulge. By correspondingly additionally arranging the bulge and the positioning groove on the thrust shoe and the bearing pedestal, the thrust shoe is no longer replaceable, and both sides can be assembled; during assembly, only one lateral face can be matched with the bearing pedestal, namely that only when the bulge is arranged in the positioning groove, can the steel back side be attached to the installation surface, thereby ensuring accurate installation.
Description
Technical field
The invention belongs to engine component and install, is a kind of bent axle thrust shoe assembly structure that prevents wrong assembling specifically.
Background technique
Existing bent axle thrust shoe 100 is the half-round symmetrical structure, and a side is a steel backing 110, and opposite side is an alloy-layer 120, sees Fig. 1-2.Correct matching requirements are that steel backing 110 is fitted (bearing support 200 structures are seen Fig. 3-4) with the crankshaft bearing seat side, alloy-layer 120 and shoulder of crank applying.Usually half-round symmetrical structure thrust shoe is changed the direction of steel backing side and alloy side and also can be assembled.Identification assembling fully artificially when the built-up crankshaft thrust shoe, if loading error, steel backing and shoulder of crank are fitted, fit in alloy-layer and crankshaft bearing seat side.Motor is in running, because steel backing and shoulder of crank are not effective wear-resisting friction pairs.The high speed relative movement that produces between steel backing and the shoulder of crank will destroy lubricant film, produce great amount of heat, cause thrust shoe and crankshaft wear very soon.Thrust shoe damages fully when serious, finally causes motor to damage.
Summary of the invention
The technical problem that the present invention will solve provides a kind of bent axle thrust shoe assembly structure that prevents wrong assembling, and misloading takes place when avoiding thrust shoe to install.
The present invention adopts following technological scheme:
A kind of bent axle thrust shoe assembly structure that prevents wrong assembling; Comprise bearing support and thrust shoe, bearing support one side is established attachment face, and thrust shoe comprises first end face and the steel backing side of adjacency; Wherein steel backing side and attachment face fit; On the position of first end face near the steel backing side, establish convexity, on attachment face, have locating slot, this locating slot cooperates with protruding.
Further, the shape of said thrust shoe and attachment face is semi-round ring shape.
Further, the opposite side of said thrust shoe is an alloy-layer.
Through corresponding increase convexity and locating slot on thrust shoe and bearing support; Making thrust shoe no longer can change the two sides all can load onto; During assembling, have only a side to match, promptly have only convexity is put into locating slot with bearing support; Steel backing side and attachment face are fitted, just mean and realized installing correctly.

Embodiment
Axial thrust of crankshaft watts 300 is symmetrical semicircular ring shape, comprises two sides and two end faces (being inside and outside anchor ring).Wherein a side is a steel backing side 310, and opposite side is an alloy-layer 320, and inner ring surface cooperates with the circumferential surface of bent axle, sees Fig. 5-6.Be end face 410 with thrust shoe 300 relative sides (being mainly upper bearing bracket) on the thrust gear shaft bearing 400 on the IC engine cylinder body, the attachment face 430 that is similarly semi-round ring shape is arranged on this end face 410, fit, see Fig. 7-8 with the steel backing side 310 of thrust shoe 300.Establish convexity 340 at first end face 330 near a side of steel backing on the thrust shoe 300, attachment face 430 is established outstanding locating slot 420 on outer shroud, and this locating slot 420 cooperates with protruding 340, sees Fig. 9-10.Locating slot can or be processed to form through casting.When assembling, convexity correctly is placed into the locating slot on the bearing support, need not to recognize that which face is a steel backing, just the debug assembling takes place fully, prevents the inefficacy that causes because of mistake assembling thrust shoe in the engine operation process.
Certainly, can on the attachment face of bearing support, establish a plurality of locating slots, correspondingly establish a plurality of convexities on the thrust shoe; Locating slot is not limit with protruding shape, but must be consistent.As long as thrust shoe has only a side to match with bearing support, just can realize the object of the invention.
Claims (3)
1. one kind can prevent the wrong bent axle thrust shoe assembly structure that assembles; Comprise bearing support (400) and thrust shoe (300), bearing support (400) one sides are established attachment face (430), and thrust shoe (300) comprises first end face (330) and steel backing side (310) of adjacency; Wherein steel backing side (310) fits with attachment face (430); It is characterized in that: on the position of first end face (330) near steel backing side (310), establish convexity (340), on attachment face (430), have locating slot (420), this locating slot (420) cooperates with protruding (340); During assembling, thrust shoe (300) has only a side and bearing support to match.
2. the bent axle thrust shoe assembly structure that prevents wrong assembling according to claim 1 is characterized in that: said thrust shoe (300) is semi-round ring shape with the shape of attachment face (430).
3. the bent axle thrust shoe assembly structure that prevents wrong assembling according to claim 2, it is characterized in that: the opposite side of said thrust shoe (300) is alloy-layer (320).
