Description

It is a kind of to prevent bearing from acting as a travelling agent the device of circle

Technical field

The utility model relates to a kind of bearing Mounting device more particularly to a kind of prevent bearing from acting as a travelling agent the device of circle.

Background technique

Support of the bearing as various rotating machineries can reduce the friction in movement, and be widely used in various machinery In structure, thus bearing products installation and use reliability be just particularly important.Interference is generally used in motorcycle product Assembly is to control the matching relationship between bearing and mounting hole.But in practical work process, since the heating of components is made At the thermal expansion of each section part, and due to the thermal expansion coefficient of material difference, the general line for installing Porous materials expands system Number will be much higher than the linear expansion coefficient of bearing material, and the assembly magnitude of interference caused between mounting hole and bearing outer ring is reduced even Failure.Therefore, bearing easily acts as a travelling agent in practical work process and encloses failure, i.e., occurs to slide relatively between bearing and mounting hole It is dynamic.Bearing portion temperature drift, vibration at this time be big, wears and aggravates between bearing outer ring and mounting base, causes the essence of components Degree and service life decline.In addition, increased frictional force is converted into most of energy useless heat and noise, transmission is reduced Efficiency.

Axially position generally is carried out to bearing using bearing baffle or groove baffle in motorcycle, is acted as a travelling agent after circle to prevent bearing Axial float, but for bearing act as a travelling agent circle after radial rotary very take corresponding counter-measure less.

Utility model content

Purpose of utility model: the utility model aim is that it is same to design a kind of energy aiming at the problem that existing bearing is acted as a travelling agent and enclosed The bearing that prevents of Shi Jinhang axially position and radial positioning is acted as a travelling agent coil apparatus.

Technical solution: the utility model includes bearing, positioning pin and bearing block, and the outer ring of the bearing is equipped with positioning Pin, the other end of the positioning pin are mounted in the corresponding pin hole of bearing block, and the bearing is band pin bearing or bearing with holes, The bearing block is integral type bearing block or split type bearing block.

The split type bearing block is the split type bearing block of No.1 or No. two split type bearing blocks.

The axis hole of No. two split type bearing blocks is equipped with No. two dowel holes, can install bearing with holes and No. two fixed Position pin.

No.1 positioning pin is pressed on the band pin shaft bearing outer-ring.

The bearing outer ring with holes is equipped with No.1 dowel hole, can install No. two positioning pins.

It is equipped with limiting slot on the axis hole of the integral bearing seat and the split type bearing block of No.1, it is fixed for installing No.1 Position pin.

The utility model has the advantages that the utility model takes the mode for increasing positioning pin on bearing outer ring and in bearing mounting hole, it is right Bearing carries out axially position and radial positioning simultaneously, encloses the generation of failure to prevent bearing from acting as a travelling agent, the present apparatus can effectively prevent by In matching allowance design is too small, machining accuracy is relatively low, bearing mounting base linear expansion coefficient is excessive, bearing operating temperatures mistake Act as a travelling agent when bearing working caused by the problems such as high and enclose failure, improve the service life of bearing and mounting hole, eliminate bearing with A series of failures such as inordinate wear, fever, vibration and noise between bearing block.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing.

As shown in Figures 1 to 5, the utility model includes bearing, positioning pin and bearing block, and the outer ring of bearing block is radially square To positioning pin is equipped with, the other end of positioning pin is mounted in the corresponding pin hole of bearing block, and bearing uses band pin bearing 4 or band Hole bearing 8, as shown in figure 3, with No.1 positioning pin 5 is pressed on 4 outer ring of pin bearing, as shown in figure 5, on 8 outer ring of bearing with holes Equipped with No.1 dowel hole 9, for assembling No. two positioning pins 10.Bearing block uses integral bearing seat 1, the split type bearing of No.1 The split type bearing block 3 of No.1 shown in seat 3 or No. two split type bearing blocks 6, integral bearing seat 1 as shown in Figure 1 and Fig. 2 Axis hole on be equipped with limiting slot 2, for install band pin bearing 4；On the axis hole of the split type bearing block 6 of as shown in Figure 4 No. two Equipped with No. two dowel holes 7, for installing bearing 8 and No. two positioning pins 10 with holes.

The device can be realized by following two mounting means:

1) be radially pressed No.1 positioning pin 5 in band 4 outer circle of pin bearing, meanwhile, in integral bearing seat 1 or Increase limiting slot 2 in the axis hole of the split type bearing block 3 of No.1, for carrying out to the No.1 positioning pin 5 in 4 outer circle of pin bearing It is axial to be limited with radial.When being assembled using integral bearing seat 1, will be pressed into integral bearing seat 1 with pin bearing 4；When When bearing block 3 split type using No.1, it is by the loading of limiting slot 2 being aligned in mounting base with the No.1 positioning pin 5 on pin bearing 4 Can, axial direction and radial positioning are carried out by 5 pairs of band pin bearings 4 of No.1 positioning pin, event is enclosed in acting as a travelling agent for preventing from occurring when bearing working Barrier.

2) radially increase No.1 dowel hole 9 on 8 outer ring of bearing with holes, meanwhile, in No. two split type bearings Increase corresponding No. two dowel holes 7 on seat 6, when assembly, first No. two positioning pins 10 are assembled in No. two split type bearing blocks 6 No. two dowel holes 7 in, then by bearing 8 with holes No.1 dowel hole 9 be aligned No. two positioning pins 10, be assembled into axis It holds in mounting hole, axial direction and radial positioning is carried out to bearing 8 with holes by No. two positioning pins 10, prevent from occurring when bearing working It acts as a travelling agent and encloses failure.

Fig. 6 to Fig. 8 is the schematic diagram completed after assembly, using the positioning pin of two ways, can carry out axis to bearing To positioning and radial positioning, acting as a travelling agent for generation encloses failure during effectively preventing bearing working.
