Abstract
The utility model discloses a high-precision bearing, comprising an outer ring, inner rings and a conical roller. The inner wall of the outer ring is an inclined face; the outer wall of each inner ring is an inclined face; a holding frame is arranged on the outer wall of each inner ring; and the inner wall of the outer ring and the outer walls of the inner rings form a roller mounting channel. The conical roller is mounted in a roller mounting channel. The inclined faces of the inner wall of the outer ring and the outer walls of the inner rings are inclined inwards; the two inner rings are respectively inserted into the outer ring from the both sides of the outer ring; and shock absorption space rings are arranged at the end parts of the inner rings. The high-precision bearing provided by the utility model has high precision; and the precision requirement of a positioning system can be met. Meanwhile, the damping space rings are mounted at the end parts of the inner ring can be used for effectively reducing noises and vibration in operation.
Description
Technical field
The utility model relates to field of bearings, relates in particular to a kind of high-precision bearing.
Background technique
Bearing is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.Press the difference of motor element frictional property, bearing can be divided into two types on rolling bearing and sliding bearing.
Mostly present widely used bearing is rolling bearing, comprises ball bearing and roller bearing.Rolling bearing is exactly that the axle of running and the sliding friction between the axle bed are become rolling friction, thus the mechanical component of a kind of precision of the loss of reducing friction.
In various machineries, the bearing constituent elements that all is absolutely necessary is that bearing also is an important component part in navigation system, and the bearing in the navigation system is higher to the requirement of precision.
The model utility content
The utility model is intended to propose a kind of high-precision bearing that can satisfy the navigation system requirement.
Embodiment according to the utility model proposes a kind of high-precision bearing, comprises outer ring, inner ring and tapered roller.The inwall of outer ring is the inclined-plane.The outer wall of inner ring is the inclined-plane, has retainer on the outer wall of inner ring, and the inwall of outer ring and the outer wall of inner ring form roller the road is installed.Tapered roller is installed in roller and installs in the road.
In one embodiment, the inclined-plane of the outer wall of the inwall of outer ring and inner ring all slopes inwardly.
In one embodiment, the quantity of inner ring is two, inserts the outer ring from the both sides of outer ring respectively.Has the damping spacer ring in the end of inner ring.
The high-precision bearing precision of the utility model is high, can satisfy the accuracy requirement of navigation system, simultaneously, the damping spacer ring is installed in the end of inner ring can effectively reduces noise and vibration when turning round.
Description of drawings
Fig. 1 has disclosed the sectional structure chart according to an embodiment's of the utility model high-precision bearing.
Embodiment
Radial bearing in the rolling bearing (bearing that refers to main bearing radial force) is made up of inner ring, outer ring, rolling element and retainer usually.Inner ring tightly is enclosed within on the axle journal and rotates together with the axis, and the outer ring is contained in the bearing saddle bore.Be shaped on raceway in the periphery of inner ring and the interior Zhou Shangjun of outer ring.When Internal and external cycle relatively rotated, rolling element promptly rolled on the raceway of Internal and external cycle, and they are separated by retainer, avoided the phase mutual friction.
Rolling element is in the radial antifriction bearing of tapered roller, can be installed respectively by assembly and outer ring that inner ring is formed with roller, retainer.The Line of contact of roller and raceway contact point correction can reduce stress and concentrate.Tapered roller bearing can bear big radial load and thrust load.Because tapered roller bearing can only transmit unidirectional thrust load, therefore, just need another tapered roller bearing of symmetry installation with it for transmitting rightabout thrust load.
With reference to shown in Figure 1, the utility model has disclosed a kind of high-precision bearing, is a kind of radial antifriction bearing of tapered roller.As shown in Figure 1, this high-precision bearing 100 comprises: outer ring 102, inner ring 104 and tapered roller 106.Outer ring 102 is installed in the bearing support, and the inwall of outer ring 102 is the inclined-plane.Inner ring 104 tightly is enclosed within on the axle and rotates together with the axis, and the outer wall of inner ring 104 is the inclined-plane.The outer wall of the inwall of outer ring 102 and inner ring 104 forms roller the road is installed.In the embodiment shown in fig. 1, the outer wall of the inwall of outer ring 102 and inner ring 104 all slopes inwardly, and the roller that forms introversion is installed the road.Because what adopt is tapered roller, so the inwall of outer ring 102 is different with the angle of inclination of the outer wall of inner ring 104.Tapered roller 106 is installed in roller and installs in the road.On the outer wall of inner ring 104, have retainer 108, retainer 108 is provided with on the outer wall of inner ring 104 at interval, and retainer 108 is spaced from each other tapered roller 106, avoids rubbing between the roller.Tapered roller 106 is installed in the road at roller and is rolled.
In the embodiment shown in fig. 1, the quantity of inner ring 104 is two, and outer ring 102 is inserted in 102 both sides from the outer ring respectively.In order to reduce the vibrations in the operation process, also be provided with damping spacer ring 105 in the end of inner ring 104.Damping spacer ring 105 can adopt the rubber elastomeric material to make, to reach the purpose of damping.
The high-precision bearing precision of the utility model is high, can satisfy the accuracy requirement of navigation system, simultaneously, the damping spacer ring is installed in the end of inner ring can effectively reduces noise and vibration when turning round.
