Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1-3, the present utility model provides the following technical solutions:
in the scheme, a connecting shaft 10, wherein a plurality of cam bodies 11 are sleeved on the outer side of the connecting shaft 10 in a threaded manner;
the oil inlet channels 12 are formed in the outer side of the cam body 11 in an array manner, and a plurality of oil inlet channels 12 are formed in the outer side of the cam body 11 in an array manner;
the connecting cover 13 and a plurality of connecting covers 13 are sleeved on the outer wall of the connecting shaft 10 in a threaded manner.
In addition, a plurality of cam bodies 11 are disposed in a lateral array on the outer wall of the connecting shaft 10.
Wherein a plurality of connecting covers 13 are arranged on the outer wall of the connecting shaft 10 in a transverse array
The cam body 11 is forged from alloy steel, so that the strength and the support degree of the cam body 11 are improved.
The oil inlet channel 12 is of a non-straight through structure, and the whole oil inlet channel 12 is of a curved structure, so that lubricating oil is slowly thrown out by centrifugal force generated when the connecting shaft 10 rotates, and the effect of long-time lubrication is achieved.
Wherein, the outer wall of one end of the connecting shaft 10 far away from the connecting cover 13 is fixedly sleeved with a gear 14.
