Abstract
The utility model relates to a super silent special-shaped pocket deep-groove ball-bearing holding rack, which is characterized in that: the bearing holding rack , the retainer ball pocket of the bearing holding rack is designed to be multilateral geometrical shape. The ball pocket of the holding rack is oval-shaped from the radial direction; the ball pocket of the holding rack is in an arc oblique line from the rotation direction of the bearing. A semicircular oil groove (5) is arranged at the joint of the two arc oblique lines, therefore, when the bearing of the structure is running at high speed, the steel ball and the holding rack can be guaranteed to move freely under high temperature, so that the movement rules of the steel balls in the ball pocket can be controlled, and the contact surface between the steel ball and the holding rack can be reduced, so that the lifecycle of the bearings can be elongated. .
Description
Technical field:
The utility model belongs to the deep groove ball bearing retainer technical field, a kind of super-silent special-shaped pocket hole depth ditch ball bearing retainer.
Background technique:
Along with new and high technology constantly develops, main frame is had higher requirement to the supporting quality of bearing, particularly to the precision bearing technical specifications of Z4 V4 group, not only require low noise to reach below 23 decibels, and require the sound equipment up-to-standard rate that is as good as of bearing to reach more than 95%, will reach super-silent technical standard exactly, the working life of guaranteeing bearing is more than 10 years.But traditional ball retainer technology is to adopt steel ball to carry out the cage ball pocket shaping, because the size of shaping steel ball is less than the standard steel ball of assembling, make cage ball pocket when shaping, the edge on the both sides in its ball pocket hole has produced two convex lines, and (jargon is referred to as: " muscle ", see accompanying drawing 1), when searching unusual sound equipment reason, find, because traditional cage ball pocket is circular or oval, its shape and steel ball coincide, make steel ball in ball pocket hole, be the unrestricted motion shape, when the steel ball load movement, can take place and the crack of cage ball pocket inward flange convex line between rub, because of this position lubricant oil lacks, can produce between the crack is unusual sound equipment in a shrill voice.Find retainer to produce the reason of unusual sound equipment, the edge convex line of eliminating two limits in the cage ball pocket is a key of eliminating unusual sound equipment.
Summary of the invention:
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of super-silent special-shaped pocket hole depth ditch ball bearing retainer, makes bearing when running up, and steel ball and retainer can guarantee that motion freely under the condition of high temperature; Can control the characteristics of motion of steel ball in ball pocket hole, reduce the surface of contact of steel ball and retainer, thereby prolong the working life of bearing.
In order to realize the foregoing invention purpose, the utility model adopts following technological scheme:
Described super-silent special-shaped pocket hole depth ditch ball bearing retainer, its cage ball pocket is designed to polygon geometrical shape; From direction radially, the ball pocket hole oval in shape of retainer, from the direction of bearing rotation, the ball pocket hole of retainer is the camber oblique line shape; Article two, the design of arc oblique line connection has semicircle oil duct.
Owing to adopted above technological scheme, the utlity model has following good effect:
This super-silent special-shaped pocket hole depth ditch ball bearing retainer, because of in design, having removed the edge convex line in ball pocket hole, the phenomenon of steel ball and the unusual sound equipment of ball pocket bore edges convex line friction-produced can not take place again, thereby eliminated unusual sound equipment, reach the supporting technical requirements of super-silent bearing.
This super-silent special-shaped pocket hole depth ditch ball bearing retainer, it has changed radially variation ε of steel ball, with the steel ball of novel retainer radially variation change 0.65mm into by 0.35mm, make bearing steel ball and retainer when running up to guarantee under the condition of high temperature, can not take place heating card ball phenomenon, guarantee that bearing operation freely.
This super-silent special-shaped pocket hole depth ditch ball bearing retainer by traditional circle or elliptical shape, is designed to polygon how much different forms with steel ball pocket hole.The characteristics of motion of steel ball in ball pocket hole can be controlled in this novel special-shaped pocket hole, reduces the surface of contact of steel ball and retainer, thereby reduces friction and collision;
This super-silent special-shaped pocket hole depth ditch ball bearing retainer, it has changed the preparation process of traditional retainer and cleaning process has been installed, in retainer tarry matter, light decorations manufacturing process, carry out four times cleaning respectively with tap water, ensured the turbidity test of retainer, then by oven dry, inunction process, retainer reaches the requirement of direct running in bearings, promptly save the energy, ensure the light decorations quality of retainer again, provide technical guarantee bearing noise reduction, the different sound of elimination.
Fig. 1 has the bearing cage structure schematic representation now:
Fig. 2 is super-silent special-shaped pocket hole depth ditch ball bearing retainer structural representation:
The super-silent special-shaped pocket hole depth ditch ball bearing retainer enlarged view of Fig. 3:
As shown in Fig. 1,2,3: the circular or oval pocket hole retainer of 1-, 2-steel ball, 3-abnormity pocket hole depth ditch ball bearing retainer, 4-abnormity pocket hole depth ditch ball bearing retainer arc oblique line, 5-oil duct.
Embodiment:
This super-silent special-shaped pocket hole depth ditch ball bearing retainer, determined radially variation ε=0.60-0.65 of new steel ball in design, with the steel ball of novel retainer radially variation change big play into by little play, simultaneously with steel ball pocket hole by traditional circle or elliptical shape, be designed to polygon how much different forms, frontal from retainer, pocket hole oval in shape, see that from the side surface direction of retainer the pocket hole is the oblique shape of camber line, the design of two arc oblique line connections has oil duct, and the characteristics of motion of steel ball in ball pocket hole can be controlled in this novel special-shaped ball pocket hole, reduce the surface of contact of steel ball and retainer, thereby reduce friction and collision.The retainer material adopts: 08A1,10,08 cold-rolled low carbon steel band or Cold Rolled Sheet Steel are made.Novel retainer deburring light decorations technology adopts vibration tarry matter machine, and abrasive material adopts the carborundum resin material, and the time is only used 20 minutes, just retainer punching press burr is removed.Enter the eddy type viberating optical decoration machine then and carry out surface treatment, abrasive material is a steel ball, and through 15 minutes light decorations, the roughness grade of retainer improved ten times, especially the effect as electroplating.
This super-silent special-shaped pocket hole depth ditch ball bearing retainer, it has changed the preparation process of traditional retainer and cleaning process has been installed, in retainer tarry matter, light decorations manufacturing process, carry out four times cleaning respectively with tap water, ensured the turbidity test of retainer, then by oven dry, inunction process, retainer reaches the requirement of direct running in bearings, promptly save the energy, ensure the light decorations quality of retainer again, provide technical guarantee bearing noise reduction, the different sound of elimination.
