Abstract
A bearing comprises a body, a ball rack and balls. The body is internally provided with the ball rack on which the balls are fixed. The middle part of the body is provided with a through hole. The upper part and the lower part of the body are provided with grooves. An embossing device of the utility model has a beneficial effect that the bearing becomes an integral member as an outer ring and an inner ring of the bearing are replaced by the bearing body. Furthermore the bearing has the following advantages: compact structure, small volume, capability of bearing force bidirectionally, low vibration, low noise, high rotation precision, reduced friction torque, improved sealing performance, easy mounting and prolonged service life.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of combined bearing that is used for machine tool chief axis.
Background technique
Bearing is the supporting element in the mechanical transmission mechanism, is used for confirming running shaft and other part relative movement positions, and its quality directly influences the service behaviour of complete machine, drives the motion of associated mechanisms through the cloud form of bearing.Bearing bears complicated applied forces such as pressure, shearing and tired impact friction in the course of the work; When particularly producing friction in the mechanism that links to each other with bearing; Consumed power not only, but also can produce certain loss to each parts of friction mutually, bearing is caused damage.
Existing nowadays, most bearing by outer ring, inner ring and be arranged on the outer ring and inner ring between ball form.These bearing seal performances are low, runnability is poor, and running accuracy is low.
The model utility content
The utility model is intended to invent, and but a kind of bidirectional stress running accuracy is high, friction torque is low, good seal performance, easy-to-install bearing.
A kind of bearing comprises main body, ball rack and ball, and body interior is provided with ball rack, is fixed with ball on the ball rack, and the main body middle part is provided with through hole, and the upper and lower of main body is provided with groove.
Preferably, described main body is cylindrical.
Preferably, through hole is cylindrical.
Preferably, described groove is a ring.
Preferably, described ball is 14～16.
The beneficial effect of a kind of knurling device of the utility model is:
1, the main body with bearing has substituted bearing outer ring and bearing inner race, makes it to become an integral body, but makes the product bidirectional stress, and running accuracy is high, and friction torque reduces, and sealability improves, and is easy to install and the raising in working life.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model.
Fig. 2 is the ball rack structural representation of the utility model.
Embodiment
Be described further below in conjunction with embodiment and accompanying drawing structure the utility model.
Fig. 1, shown in 2, a kind of bearing comprises main body 1, ball rack 3 and ball 4, main body 1 inside is provided with ball rack 3, is fixed with ball 4 on the ball rack 3, main body 1 middle part is provided with through hole 5, the upper and lower of main body is provided with groove 2.
Claims (5)
1. bearing, it is characterized in that: comprise main body, ball rack and ball, body interior is provided with ball rack, is fixed with ball on the ball rack, and the main body middle part is provided with through hole, and the upper and lower of main body is provided with groove.
