Abstract
The utility model provides a bearing seat capable of adjusting a bearing clearance and a crankcase connecting structure. A threaded hole and a sliding fit hole are sequentially formed in a through hole, matched with the bearing seat, of a crank shaft, a crank shaft conical bearing adjusting gear is arranged in the threaded hole and the sliding fit hole, the threaded section of the crank shaft conical bearing adjusting gear is in threaded connection with the threaded hole, matched with the bearing seat, of the through hole of the crank shaft, the inner end of the threaded section of the crank shaft conical bearing adjusting gear is propped against the outer ring of the crank shaft conical bearing, the sliding fit section of the crank shaft conical bearing adjusting gear is arranged in the sliding fit hole, matched with the bearing seat, of the through hole of the crank shaft in a sliding manner, and an oil seal is arranged between the outer port of the crank shaft conical bearing adjusting gear and the crank shaft. According to the utility model, when noise caused by abrasion of the conical bearing to a machine is increased, a user only needs to rotate the crank shaft conical bearing adjusting gear so as to enable the inner end of the threaded section of the crank shaft conical bearing adjusting gear to extrude the outer ring of the crank shaft conical bearing inward, the fit clearance of two bearings is reduced, and the bearing clearance is adjusted without detaching the bearing seat, so that convenience and fastness are realized.
Description
Technical field
The utility model relates to a kind of bearing support and crankcase linkage structure, specifically relates to a kind of bearing support and the crankcase linkage structure that can regulate bearing play.
Background technique
The crankshaft end of crankcase adopts conical bearing that bent axle is supported on bearing support usually, conical bearing wearing and tearing after the machine long-play, cause the bearing fit gap to increase, the compressor operation noise increases, befouling environment, also affect machine service life, need to change bearing or take bearing support apart and regulate just and can address the above problem when serious, comparatively trouble.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, and a kind of bearing support and the crankcase linkage structure that can regulate bearing play is provided.
above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of bearing support and the crankcase linkage structure that can regulate bearing play, the bearing support that comprises crankcase and fixed crankshaft conical bearing, on the through hole of described bearing support cooperation bent axle, from-inner-to-outer is provided with tapped hole and the sliding hole of joining successively, tapped hole and the sliding hole of joining are provided with bent axle conical bearing adjusting shelves, the thread section that the bent axle conical bearing is regulated shelves is screwed onto on the tapped hole of bearing support cooperation bent axle through hole, the inner top of thread section that the bent axle conical bearing is regulated shelves is located on the outer ring of bent axle conical bearing, the cunning section of joining of bent axle conical bearing adjusting shelves is slidably installed in bearing support and coordinates the cunning of bent axle through hole to join on hole, the bent axle conical bearing is regulated between shelves external port and bent axle and is provided with oil sealing.
As preferably, the stub end that described bent axle conical bearing is regulated shelves is provided with stop screw, via stop screw, the bent axle conical bearing is regulated shelves spacing on bearing support.
The utility model is set up the bent axle conical bearing and is regulated shelves, when finding that conical bearing abrasion machine noise increases, only need the rotary crankshaft conical bearing to regulate shelves, the thread section the inner that makes the bent axle conical bearing regulate shelves is pushed the outer ring of bent axle conical bearing inward, reduce the matching gap of bearing, can complete and regulate bearing play, need not to take apart bearing support and regulate, convenient and swift.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
embodiment: the utility model comprises the bearing support 2 of crankcase 1 and fixed crankshaft conical bearing 7, on the through hole of bearing support 2 cooperation bent axles 4, from-inner-to-outer is provided with tapped hole 22 and the sliding hole 21 of joining successively, tapped hole 22 and the sliding hole 21 of joining are provided with bent axle conical bearing adjusting shelves 3, the thread section 32 that the bent axle conical bearing is regulated shelves 3 is screwed onto on the tapped hole 22 of bearing support cooperation bent axle through hole, the inner top of thread section 32 that the bent axle conical bearing is regulated shelves 3 is located on the outer ring of bent axle conical bearing 7, the cunning section of joining 31 of bent axle conical bearing adjusting shelves 3 is slidably installed in bearing support and coordinates the cunning of bent axle through hole to join on hole 21, the bent axle conical bearing is regulated between shelves 3 external port and bent axle 4 and is provided with oil sealing 5.The stub end 33 that the bent axle conical bearing is regulated shelves 3 is provided with stop screw 6, via stop screw 6, the bent axle conical bearing is regulated shelves 3 spacing on bearing support 2.The utility model is set up the bent axle conical bearing and is regulated shelves, when finding that conical bearing abrasion machine noise increases, only need the rotary crankshaft conical bearing to regulate shelves, the thread section the inner that makes the bent axle conical bearing regulate shelves is pushed the outer ring of bent axle conical bearing inward, reduce the matching gap of bearing, can complete and regulate bearing play, need not to take apart bearing support and regulate, convenient and swift.
Finally, should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model, to any simple modification, equivalent variations and modification that above embodiment does, all should be thought and belong to protection domain of the present utility model.
