Abstract
The utility model provides an air compressor motion structure which comprises a piston, a piston pin, a connecting rod and an oil repellent needle. The air compressor motion structure further comprises a roller pin bearing. The piston pin is fixed on the skirt portion of the piston. The middle of the piston pin and the pin hole end of the connecting rod are connected through the roller pin bearing. The oil repellent needle is fixed at the bottom of the connecting rod. According to the air compressor motion structure, a connecting rod pin hole is changed to be connected with the piston pin through the roller pin bearing, the roller pin bearing can bear the higher load capacity, and the air compressor motion structure is even in lubricating, low in noise and long in machine continuous operating time.
Description
Technical field
The utility model relates to mechanical field, specifically a kind of air compressor motion structure.
Background technique
In the fault of air compressor, link pin nose end fracture is a kind of very common fault wherein, its reason normally link pin nose end is to adopt copper sheathing to be pressed in the connecting rod pin-and-hole, used for air compressor behind the many decades, copper sheathing because the link pin nose end of air compressor rubs for a long time in the connecting rod pin-and-hole, make copper sheathing that wearing and tearing occur, and wear extent has surpassed the gap between link pin nose end and copper sheathing, thereby make air compressor again during punching parts, the power that bent axle is passed to connecting rod has acted directly on the link pin nose end rather than on the copper sheathing, in the course of time just the link pin nose end is sheared and broken, cause machine failure; In addition, copper sheathing is pressed in the connecting rod pin-and-hole, and then the processing copper sheathing, cuts oil groove again, and it is cumbersome therefore to have processing technology, and noise is large, not wear-resisting relatively, the shortcomings such as machine weak point working time.
The model utility content
The technical problems to be solved in the utility model is to overcome existing defective, and a kind of air compressor motion structure is provided, and can bear higher load carrying capacity, and lubricious even, noise is low, and the machine continuous operating time is long.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of air compressor motion structure comprises piston, wrist pin, connecting rod and dials spindle that also comprise needle bearing, the skirt section of piston is fixed with wrist pin, and the middle part of wrist pin is connected by needle bearing with the pin-and-hole end of connecting rod, and the bottom of connecting rod is fixed with dials spindle.
Further, needle bearing is the needle bearing without inner ring.
A kind of air compressor motion structure of the utility model, the connecting rod pin-and-hole is used needle bearing instead and is connected with wrist pin, and needle bearing can bear higher load carrying capacity, and lubricious even, noise is low, and the machine continuous operating time is long.
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 the structural representation of a kind of air compressor motion structure of the utility model.
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 air compressor motion structure as shown in Figure 1, comprise piston 1, wrist pin 2, connecting rod 4 and dial spindle 5 that also comprise needle bearing 3, the skirt section of piston 1 is fixed with wrist pin 2, the middle part of wrist pin 2 is connected by needle bearing 3 with the pin-and-hole end of connecting rod 4, and the bottom of connecting rod 4 is fixed with dials spindle 5.Further, needle bearing 3 is the needle bearing 3 without inner ring.
A kind of air compressor motion structure of the utility model, connecting rod 4 pin-and-holes are connected employing needle bearing 3 with wrist pin 2, needle bearing 3 can bear higher load carrying capacity, and lubricious even, noise is low, and the machine continuous operating time is long; Needle bearing 3 is not to be with inner ring, and the journal surface that match with bearing this moment and shell aperture surface are directly as the inside and outside rolling surface of bearing, and load-carrying ability is strong, and surface roughness is lower.
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.
