Abstract
The utility model provides a connecting rod and crank shaft assembly connected by a needle bearing with inner rings. The connecting rod and crank shaft assembly comprises a crank shaft and a connecting rod, and further comprises the needle bearing. The connecting rod is connected with the crank throw diameter of the crank shaft through the needle bearing, the needle bearing comprises the needle bearing inner rings and needle bearing outer rings, the needle bearing inner rings are fixed on the two sides of the crank throw diameter of the crank shaft, and the needle bearing outer rings are fixed in a connecting hole of the connecting rod and the crank shaft. According to the connecting rod and crank shaft assembly connected by the needle bearing with the inner rings, the connecting rod is connected with the crank throw diameter of the crank shaft through the needle bearing with the inner rings, noise of a machine is reduced, even lubrication is carried out, and the service life is prolonged.
Description
Technical field
The utility model relates to mechanical field, connecting rod and crankshaft group that specifically a kind of employing connects with the inner ring needle bearing.
Background technique
Bent axle and the connecting rod of air compressor connect into assembly.Existing connecting rod directly adopts bearing shell to be connected with crankshaft crank, used for air compressor behind the many decades the bearing shell between them because the connecting rod of air compressor and crankshaft crank directly can rub for a long time makes bearing shell that wearing and tearing occur, and causes scrapping bearing shell, user cost is large; Set noise is large simultaneously, and service life of a machine is directly shortened in the wearing and tearing of bearing shell.
The model utility content
The technical problems to be solved in the utility model is to overcome existing defective, and connecting rod and the crankshaft group of a kind of employing with the inner ring needle bearing connects is provided, and set noise is reduced, and is evenly lubricated, and ILS.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
Connecting rod and crankshaft group that a kind of employing connects with the inner ring needle bearing, comprise bent axle and connecting rod, also comprise needle bearing, connecting rod is connected by needle bearing with the crank throw footpath of bent axle, needle bearing comprises needle bearing inner ring and needle bearing outer ring, the needle bearing inner ring is fixed in the both sides, crank throw footpath of bent axle, and the needle bearing outer ring is fixed in connecting rod and the bent axle attachment hole.
Further, the crank throw of connecting rod and bent axle directly is orthogonal.
Connecting rod and crankshaft group that a kind of employing of the utility model connects with the inner ring needle bearing, connecting rod and crankshaft crank directly adopt band inner ring needle bearing, and set noise is reduced, and be evenly lubricated, and ILS.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and consists of the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
Fig. 1 is that a kind of employing of the utility model is with the connecting rod of inner ring needle bearing connection and the structural representation of crankshaft group.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
A kind of employing is with connecting rod and the crankshaft group of the connection of inner ring needle bearing as shown in Figure 1, comprise bent axle 1 and connecting rod 4, also comprise needle bearing, the crank throw footpath 11 of connecting rod 4 and bent axle 1 is connected by needle bearing, needle bearing comprises needle bearing inner ring 2 and needle bearing outer ring 3, needle bearing inner ring 2 is fixed in 11 both sides, crank throw footpath of bent axle 1, and needle bearing outer ring 3 is fixed in connecting rod 4 and bent axle 1 attachment hole.Further, connecting rod 4 is orthogonal with the crank throw footpath 11 of bent axle 1.
Connecting rod and crankshaft group that a kind of employing of the utility model connects with the inner ring needle bearing, it is to adopt band inner ring needle bearing that connecting rod 4 is connected with the crank throw footpath 11 of bent axle 1, and needle bearing inner ring 2 is fixed in 11 both sides, crank throw footpath of bent axle 1, and set noise is reduced, evenly lubricated, and ILS.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
