The camshaft convenient to assemble is convenient to assemble and disassemble, lubricating oil is convenient to add, good lubricating performance is achieved, leakage of the lubricating oil is convenient to reduce, and the camshaft is convenient to achieve good bearing performance and wear resistance, so that the service life of the camshaft is long.

This patent has the following drawbacks: in the use process, the lubricating oil is inconvenient to add, the lubricating oil is difficult to have good lubricating performance, and the service life of the camshaft is difficult to be long.

Accordingly, the present application now proposes a camshaft that is convenient to assemble to solve the above-mentioned problems.

Disclosure of Invention

The utility model aims to provide a camshaft which is convenient to assemble, so as to solve the problems that lubricating oil is inconvenient to add, good lubricating performance is difficult to achieve, and the service life of the camshaft is difficult to be long in the use process.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

a camshaft that facilitates assembly, comprising:

the outer side of the connecting shaft is in threaded sleeve connection with a plurality of cam bodies;

the cam body is provided with a plurality of oil inlet channels in an array at the outer side;

the connecting covers are in threaded sleeve connection with the outer wall of the connecting shaft.

Further, a plurality of cam bodies are arranged on the outer wall of the connecting shaft in a transverse array mode.

Further, a plurality of the connecting covers are arranged on the outer wall of the connecting shaft in a transverse array mode.

Further, the cam body is forged from alloy steel.

Further, the oil inlet channel is of a non-straight through structure, and the whole oil inlet channel is of a bent structure.

Further, the outer wall of one end of the connecting shaft far away from the connecting cover is fixedly sleeved with a gear.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, lubricating oil can be stored in the oil inlet channel on the cam body, and in the working process of the connecting shaft, the lubricating oil slowly seeps outwards along with the oil inlet channel through the rotation of the connecting shaft, so that the effect of long-time lubrication by adding the lubricating oil once is realized, the time of adding the lubricating oil by workers is saved, and the structure ensures that the cam body has good lubricating performance and the service life of the cam body is prolonged to a certain extent.

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.

Working principle: can store lubricating oil in the oil feed passageway 12 on the cam body 11, at the during operation that connecting axle 10 advances, make lubricating oil slowly along with oil feed passageway 12 is to the exosmosis, realize adding the effect that once lubricating oil can lubricate for a long time, practiced thrift workman's time of adding lubricating oil, this structure makes cam body 11 have good lubricating property, has prolonged the life of cam body 11 to a certain extent.

The present utility model has been illustrated by the above-described embodiments, but it should be understood that the above-described embodiments are for purposes of illustration and description only and are not intended to limit the utility model to the embodiments described.
