Bearing 6204: the 78 electric cars do you want to change the bearing

Bearing seat and bedplate, bedplate and loose coupling between base, combined with the uneven surface contact, loose time grouting, walking at the bottom of the table mat iron, etc are likely to induce axial vibration. Outer ring outerrin - Methyl amino acetonitrile g race, on the surface of the bearing ring, outer ring lock mouth coun - Methyl amino acetonitrile terboredouterrin - Methyl amino acetonitrile g a shoulder removal of all or part of groove type ball bearing outer ring. a) With shaft with retaining ring embedded in the shaft inside the groove, it is mainly used for axial force is not big and the speed is not high; b) With screw shaft end ring fastening, can be used under the high speed under large axial force, should be screw locking measures; c) With a round nut and lock washer with fastening, mainly used in high speed, large axial force; d) With conical sleeve, lock washer with and round nut fastening, used in optical axis, the inner ring for the taper hole of the bearing. Conical bore taperedbore the inner hole of bearing or bearing parts, its basic for bus line and intersecting axis bearing axis or bearing parts. Bearing and bearing cover amount: the bearing cover for oil bearing cover capacity / ~ / ( The number of motor high ceiling) ； Bearing oil bearing inner and outer ring cavity / ~ ( The number of motor high ceiling) 。 In the point above the angular position or in the vicinity of the rolling element should be on both sides of the with the inner and outer ring raceway or inner ring on the back of the rim ( Tapered roller bearing) Faces in contact, that is, bearing the relative position of the parts are in normal. GCr bearing steel, including c, steel ball, the diameter & amp; gt; Mm roller; In addition can also be requested high hardness, high wear resistance of other mechanical parts, such as roll. Life ( Refers to the set of bearing) Life of a bearing ring or a washer or a rolling element material fatigue before expansion appeared for the first time, a ring or a washer relative to the other a ring or a washer of the revolution. In this case the emergency stop, overhauling pinion shaft bearing, found that small gear shaft support side bearing damage, and bearing wear, originally diameter mm diameter of the bearing, now wear after the size is mm, mm diameter size abrasion, uneven wear depth of mm, with partial abrasion is more serious. CNC parts can provide years of shelf life, plastic and flat roof bearing don't put wrong as long as the vehicle is in the process of rising state will always keep replacement nut screw on the shock absorber. Then on the peak, Waveform) Sampling and processing, get Pevue waveform and spectrum, as a result, the peak power can effect in the rolling bearing status monitoring. According to motor bearing chamber wear problem, traditional solutions such as machining, Mosaic collar after repair welding, brush plating, spraying, pitting, scrap, etc. , these methods are in definite extent cope with the demands of the production, but can't fundamentally solve the problem, and continuous production also planted hidden danger to safety, such as high temperature deformation, crack, coating fall off; At the same time, the continuation of the traditional methods of equipment management work also won't bring substantial improvement.
