Description
Technical field
This utility model belongs to contact ball bearing technical field, and it is long to be specifically related to a kind of service life, with low cost, economical environment-protective, easy-to-install four-point contact ball.
Background technology
It is known that bearing is a kind of important spare part in plant equipment in the present age.Its major function is to support machinery rotary body, reduces the coefficient of friction in its motor process, and ensures its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling bearing and the big class of sliding bearing two.Wherein rolling bearing is the most normalized, seriation, but its radial dimension, vibration and noise are relatively big compared with sliding bearing, and price is the highest.
Rolling bearing is typically made up of outer ring, inner ring, rolling element and retainer four part.By the shape of rolling element, rolling bearing is divided into ball bearing and the big class of roller bearing two.Wherein keeper is one of vitals of rolling bearing, and its effect is to guide rolling element to run well in bearing working, at any time keeps rolling element without departing from bearing.It addition, in order to obtain preferable operating condition or mounting condition, keeper the most also need control the rolling element free movement relative to keeper, can not rolling element be limited narrow so that can not be freely rotatable, pine can not be crossed so that assembling or installation difficulty.Generally, keeper be by constraint rolling element outer surface keep rolling element without departing from, described outer surface is ball surface to ball bearing speech, it is outer round surface to roller bearing speech, it is the most all load-bearing surface or the working surface of rolling element, so inevitably working surface is produced impact when there is effect of contraction, as lubricant flow to, abrasion difference etc., thus affect the performance and used life of bearing.
In prior art, due to unstability and the production technology of its structure, cause production process to pollute environment, while not only increase cost and decrease again service life；Its retainer material is usually copper and nodular cast iron, and wherein the shortcoming of copper cage is that cost is high, at the bottom of wear-resistant degree, reduces bearing service life.Trouble is installed, its pocket hole is open, first spin is put in the retainer in open pocket hole during installation, retainer lock spin is split again with special drill rod, split is a little four, this technology is the technology in last century, its shortcoming is to split retainer lock spin with drill rod, people's strength not of uniform size also causes can't lock spin and causes falling ball, and the mode of this lock ball causes spin radial-play gap in bearing channel the biggest, cause the abrasion of mutual play increase copper cage lock point during bearing rotary, decrease the life-span of bearing.Its Principle of Rotating be with roller branch line face contact, during it is also possible to directly lubricating oil rotate scrape；But bearing during installation uses can high speed rotating with vibrations, if having lubricating oil to reduce and wearing away the interference of powder, this not only increases the abrasion of bearing, weares and teares and excessive easily falls ball, also reduces the service life of bearing.
Summary of the invention
The purpose of this utility model is to provide long, with low cost Yu easy for installation four-point contact ball in a kind of service life.
The technical solution of the utility model is: a kind of four-point contact ball, and it includes outer ring, inner ring, retainer, spin, it is characterised in that: being evenly distributed with the pocket hole guiding spin on described retainer circumferencial direction, described pocket hole is enclosed construction；Also it is provided with the lock point to pocket hole center position on the inwall arc surface in described pocket hole, between described spin and lock point, there is the lubricating place of 0.5 ± 0.05mm, and pocket hole hold depth hammers into less than ball diameters 0.3 ± 0.05mm, described spin from retainer lock point.Described lock point quantity is 4.Described retainer is 08AL sheet material material.
This utility model advantage is, this utility model uses the pressing cage that 08AL material does, and its advantage is: reduce cost 50% price.Its advantage of 08AL material is that impact resistance is wear-resistant, solve the problem that copper cage during bearing operation rubs off powder, and pressing cage just devises the pocket hole less than ball diameters 0.3MM hold depth man-hour adding, need not manually split retainer lock ball, size is unified, installing simple, during installation, spin is directly outer hammers in retainer, and spin radial-play gap in bearing channel is less than spin raceway groove radial-play gap in copper cage.Lock point has the lubricating place of 0.5MM to enhance greasy property with spin, enhances the service life of bearing simultaneously.In installation, the time that copper cage is installed was at 10-15 minute.The pressing cage set-up time is 1-2 minute.In terms of economical environment-protective, copper cage it forging type must be needed to process, pollute environment and also waste resource.And the pressing cage gone out by 08AL manufacture of materials, direct sheet material cold working is pollution-free, and stock utilization is high.
