Description

A kind of power output component in Cam splitter

Technical field

The utility model belongs to field of mechanical technique, is related to a kind of Cam splitter, in especially a kind of Cam splitter Power output component.

Background technique

Cam splitter, in engineering also known as cam protractor, indexing separator.It is a kind of high-precision revolution dress Set, be realize intermittent movement mechanism, have indexing accuracy height, smooth running, transmit torque it is big, it is compact-sized, small in size, make an uproar The distinguishing features such as sound is low, high speed performance is good, the service life is long are substitution Geneva mechanisms, ratchet mechanism, incomplete gear mechanism, the qigong The ideal product of the traditional mechanisms such as control mechanism.

In order to realize the permanent high-precision operation of Cam splitter, need to add lubricating oil at runtime to reduce cam The abrasion of roller and indexed cam.In order to guarantee lubricant effect, need to guarantee that indexed cam is located at the gear teeth of lower part and is immersed in profit In lubricating oil, it is therefore desirable to pour into more lubricating oil and just be able to achieve, exist between cam bawl and indexed cam when due to operation Inevitably abrasion, abrasion can generate some metal particles, and metal particle can exist in lubricating oil, the presence meeting of metal particle So that the abrasion of cam bawl and indexed cam aggravates, therefore no operation a period of time does not just need replacing lubricating oil；Due to lubrication The usage amount of oil is larger, therefore the amount of each more oil change is also larger, causes operating cost higher；Existing replacement lubrication simultaneously Be to pour into new lubricating oil after bleeding off old lubricating oil when oily, can be adsorbed in the gear teeth of indexed cam due to lubricating oil and The lower part of the gear teeth is also immersed in lubricating oil before bleeding off, therefore the lower part of the gear teeth is also adsorbed with one during bleeding off lubricating oil Quantitative lubricating oil, these lubricating oil have little time to bleed off, therefore metal particle is had when pouring into new lubricating oil in casing A small amount of lubricating oil can be mixed into new lubricating oil, cause to have replaced and still remain metal particle, shadow in lubricating oil after lubricating oil The service life and service precision of Cam splitter are rung；Existing cam bawl is fixed on out in such a way that screw rod is spirally connected On power capstan head, the degree of tightening will affect relative position of the screw rod in the axial direction with power output capstan head when screw rod is spirally connected, that is, It will affect the position of camshaft bearing, therefore also need to be repeatedly detected the fixation position of each cam bawl in fixed cam bawl Whether in place, it assembles more complex.

Summary of the invention

The purpose of this utility model is the presence of the above problem in view of the prior art, is proposed in a kind of Cam splitter The technical issues of power output component, the utility model solves is that the assembling of power output component is more complex.
