Abstract
The utility model belongs to the technical field of bearings and relates to a novel disc type nylon retainer two-way thrust angular contact ball bearing, which is composed of an outer ring, inner rings, a steel ball, a retainer and a spacer ring, wherein the outer ring is connected with the inner rings through the steel ball, the two inner rings are connected through the spacer ring, the steel ball is arranged in the retainer, the retainer is made of engineering plastic nylon, a ball bag hole of the retainer is composed of a spherical surface, a corresponding spherical surface, a cylindrical surface and a corresponding cylindrical surface, and the spherical surface and the corresponding spherical surface have same curvature. The novel disc type nylon retainer two-way thrust angular contact ball bearing can resist repeated impact vibration and lowers the vibration noise of the main machine, and the frame has strong shock and vibration absorption. The bearing has good abrasion-resistance, low frication factor and good self-lubricating property.
Description
Technical field
The utility model belongs to technical field of bearings, relates to a kind of novel dish type nylon retainer bidirectional thrust force angular contact ball bearing, is applied to machine tool field such as accurate digital control milling machine, boring machine, machining center.
Background technique
Along with the continuous development of China's machine industry, especially machine tool structure is brought in constant renewal in, and the required precision of main shafts such as some accurate digital control milling machines, boring machine, machining center is more and more higher, and noise is more and more lower.The old airframe bearing that supports accurate main shaft has been difficult to satisfy the requirement of the highi degree of accuracy of lathe, low friction, low noise.
At the requirement of accurate main shaft, invent a kind of novel dish type nylon retainer bidirectional thrust force angular contact ball bearing, overcome the shortcoming of old infrastructure product, adapt to the demand in precision machine tool field.
Summary of the invention
The purpose of this utility model provides the novel dish type nylon retainer bidirectional thrust force angular contact ball bearing, and this bearing wear-resisting property is good, and friction factor is low, and self lubricity is good.
Technical solution of the present utility model is: a kind of novel dish type nylon retainer bidirectional thrust force angular contact ball bearing, form by outer ring 1, inner ring 2, steel ball 3, retainer 4, spacer ring 5, outer ring 1 is connected by steel ball 3 with inner ring 2, two inner rings 2 are connected by spacer ring 5, steel ball 3 is located in the retainer 4, and retainer 4 is made for engineering plastic nylon; The ball pocket hole of retainer 4 is made up of sphere 6 and corresponding sphere 7 and cylndrical surface 8 and corresponding circle cylinder 9, and the curvature of sphere 6 and corresponding sphere 7 equates.Hold frame steel ball is gone slick in retainer pocket hole, improved steady, the flexibility of running of bearing, reduce frictional force and noise.The retainer complex structure, suitable with the gap of Internal and external cycle, the containing amount of steel ball is big, and wall thickness makes the contraction of nylon bracket even uniformly.Design the ball pocket forms that two sections spheres and two sections cylinders are formed, satisfy nylon bracket and pull out and touch and Shooting Technique.Reasonably the pocket hole is made up of two sections spheres, two sections cylndrical surface, and reasonably curvature and off-centre are suitable to guarantee dress ball hold depth.
The beneficial effects of the utility model are, the anti-repeated stock vibrations of bearing have reduced the main frame vibrating noise, and the frame absorbing is strong.The bearing wear-resisting property is good, and friction factor is low, and self lubricity is good, and effective contact that has both guaranteed retainer and raceway also makes rolling element go slick in retainer pocket hole, steadily, flexibly simultaneously, thereby realizes the low friction of product, low noise requirement.
