Abstract

The utility model relates to a split rolling bearing, which belongs to a rolling bearing, used for motor vehicles or a plurality of bearings used for matching on a shaft with special shapes, composed of a bearing outer ring, an inner ring, a cage arranged in the inner ring and a rolling body. The utility model is characterized in that the bearing outer ring and the inner ring are respectively provided with a split structure; the split contacts of the split structures are formed into an angle with a bearing axis. The utility model has the advantages that the rolling bearing and a sliding bearing are integrated as a whole; the assembly process of bearings are simplified; rotation accuracy is improved; service life is long, lubrication is simple; friction force is small, when an engine is under a low speed; energy consumption is low; the utility model is particularly suitable for the use by matching with shafts with special shapes.

Description

Split type rolling bearing

A kind of split type rolling bearing belongs on the automobile and can't assemble the axle of rolling bearing as the bearing of assembling on the bent axle with some.

At present, use wider bearing and mainly be two kinds on rolling bearing and sliding bearing, and rolling bearing is an overall structure, sliding bearing is for dividing body structure, rolling bearing adopts rolling element, tool frictional force is little, laborsaving during machine operation, economize characteristics such as merit and life-span be long, therefore used in a lot of fields widely.Sliding bearing is also used widely owing to the progress of Machining Technology and lubrication technology.But they all come with some shortcomings, rolling bearing is an overall structure, can not be in radial separation, can't be installed on the axle of bent axle and complex structure, but though sliding bearing radial separation, but sliding bearing is to adopt high-tension lubrication, axle with watt between produce the high pressure oil film, along with the rotating speed increase of axle, the pressure of oil film increases, surface friction drag reduces, and bearing capacity strengthens, the axle that sliding bearing is suitable for running up, on lower velocity shaft axle with watt because the oil film pressure of the low generation of rotating speed is little, frictional force increases that then energy loss is big, and in the lubrication system of insufficient lubrication or lubrication system when breaking down, sliding bearing lost efficacy, cause tile kilning, damage problems such as mechanism, plain bearing bush must carry out scraping before assembling, could assemble the assembly technology complexity then.

The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of split type bearing of getting sliding bearing and rolling bearing advantage is provided, and simplifies maintenance, repair, installation and complicated lubrication system.

The utility model is realized with following technological scheme: it comprises bearing outer ring, bearing inner race and within it retainer and rolling element is installed, and bearing outer ring and bearing inner race be for dividing a body structure, its minute contact level and the axis of bearing constitute at an angle.

The beneficial effect that the utility model had: because this bearing is a split-type structural, its minute contact level and axis at an angle, like this, when assembling, bearing radially adds a power, radially will produce small variation, bearing Shang Quan and following circle then produce small moving axially, so very easily adjust the radial clearance of bearing, simplify assembly technology, and improved rotation precision.Compare with sliding bearing, this bearing long service life is lubricated simple, motor frictional force when low speed is little, energy consumption is low, and this bearing integrates the advantage of rolling bearing, sliding bearing, is particularly suitable on the automobile or the axle of some structure shape complexity is gone up supporting use.

Further specify the utility model below in conjunction with drawings and Examples.

Fig. 1 cuts open structural representation for the three-dimensional office of split type rolling bearing;

Fig. 2 is the bearing partial view radially on plane for the branch contact level of split type rolling bearing;

Fig. 3 is the bearing partial view radially of V-shape for the branch contact level of split type rolling bearing.

Fig. 1 to Fig. 3 has provided the structural representation of the most preferred embodiment of split type rolling bearing, it comprise bearing outer ring, bearing inner race and installation within it retainer and retainer on the rolling element installed.Its feature is that bearing outer ring, bearing inner race and retainer split are become on the bearing outer ring 6 under outer ring 2, the bearing, retainer 7 under inner ring 5, holder 3 reach under inner ring 4, the bearing on the bearing, its minute contact level and the axis of bearing between angle can be controlled between 15 °～45 °, present embodiment is 30 °, by Fig. 2 and Fig. 3 provided respectively divide to become between contact level and bearing axis 30 ° of angles and be the structural type of lineal shape oblique section and V-shape shape section, the lineal shape oblique section that Fig. 2 provides divides the bearing of body structure, at when assembling preloaded bearing automatically.Fig. 3 provide for V-shape divides contact level and is example with the bearing outer ring that is made of outer ring on the bearing 2 and following outer ring 6, this section is pretension automatically.Rolling element 1 adopts roller or needle roller and without steel ball, because roller or needle roller are that line contacts with the inside and outside circle of split type bearing when changeing, motion is continuous.

Claims

1, a kind of split type rolling bearing comprises bearing outer ring, bearing inner race and within it retainer and rolling element is installed, and it is characterized in that bearing outer ring and bearing inner race for dividing a body structure, its minute contact level and the axis of bearing at an angle.
