Description

A kind of lifting device

Technical field

The utility model belongs to detection technique field, more particularly, to a kind of lifting device.

Background technology

Bearing is a kind of important parts in contemporary mechanical equipment, when its major function supports mechanical rotary body, drop Friction coefficient in its low motion process, and ensure its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into Two major class of rolling bearing and sliding bearing, rolling bearing are generally made of outer ring, inner ring, rolling element and four part of retainer, sternly Saying for lattice is made of outer ring, inner ring, rolling element, retainer, sealing, six big part of lubricating oil.In simple terms, as long as possessing outer Circle, inner ring, rolling element just may be defined as rolling bearing.By the shape of rolling element, rolling bearing is divided into ball bearing and roller bearing Two major classes.

During bearing task, not only break out rolling friction between outer ring, rolling element and retainer, and the slip that can break out rubs Wipe, so that bearing parts is right worn.In order to reduce the abrasion of bearing parts, bearing accuracy stability, extension fortune are maintained With the service life, this, which allows for outer ring, should have more preferable precision, so as to lower the friction coefficient between outer ring and rolling element.Bearing is studied carefully It should be support for acting on, i.e., literal interpretation is used for holding axis, but this is a part for its effect, supports its essence just It is that can undertake radial load.It can be appreciated that it is for fixing axle, it is exactly that fixing axle makes it to realize rotation, and Control its movement axially and radially.

In the qualified detection of bearing, its dimensional accuracy, running accuracy, internal clearance and mating surface, rolling are checked emphatically Road face, retainer and sealing ring.The wherein size precision most basic as bearing, it is especially desirable to accurate.Bearing in use, , can there are gap, the athletic meeting of axostylus axostyle when bearing size precision is not high, between bearing and axostylus axostyle due to being socketed axostylus axostyle in bearing The vibration of axostylus axostyle within the cleft is driven, so that bearing causes fatigue damage, with the influence of fatigue, gradually occurs and shakes There is fatigue rupture in dynamic speed and the rise of displacement, bearing.

, it is necessary to will detect that underproof product is separated in the detection process of bearing, depart from substandard product In qualified products.In the detection of bearing, since bearing is run on specified Transfer pipe, substandard product is rejected, is needed Substandard product is departed from into its original running track.

In the prior art, operating personnel usually require manually to take away substandard product, this, which allows for operating personnel, needs All the time detection device is stared at, it is substandard product which the moment, which observes, in time rejects substandard product, is thus increased The workload of operating personnel, while easily there is operating mistake, the situation misunderstood or taken by mistake.
