Specific implementation mode
The utility model is further described With reference to embodiment, wherein being given for example only property of attached drawing
Illustrate, expression is only schematic diagram rather than pictorial diagram, should not be understood as the limitation to this patent；In order to which this reality is better described
With novel embodiment, the certain components of attached drawing have omission, zoom in or out, and do not represent the size of actual product；To ability
For field technique personnel, the omitting of some known structures and their instructions in the attached drawings are understandable.
Embodiment
The bearing fixing structure of steering column as shown in Figure 1, including bearing block 1, bearing 2 and axis 3, as shown in figure 4, its
Bottom bracket 1 has endoporus 11 for installing bearing 2, and 11 bottom of endoporus limits bearing first end equipped with step groove 12
Position, 11 hole wall of endoporus protrude from bearing seating face and form seam allowance 13, and seam allowance 13 is circumferentially being evenly distributed at least two fasteners
14 to bearing the second end for carrying out abutting fixation.
The bearing fixing structure of the present embodiment is mainly by the combination setting of step groove 12 and fastener 14 by 2 liang of bearing
A end compresses to firm bearing, prevents bearing from damaging by pressure, deforming or beat play occurs, evade from source and being caused by bearing
Abnormal sound or clamping stagnation problem.
Preferably bearing to be convenient for install, prevent bearing 2 from hardness occurs with fastener 14 during being placed in endoporus 11
Interference, as shown in figure 3, at least two notches 131 can be uniformly arranged in the circumferential direction of seam allowance 13, above-mentioned fastener 14 is embedded
In notch 131, fastener 14 has slight elasticity, and so, fastener 14 is independently arranged with seam allowance 13, along bearing
Height extends, and when interfering, fastener 14 can be by bearing 2 toward 13 peripheral direction force feed of seam allowance.
There is no limit can be odd number can also be even number, fastener is arranged in the present embodiment to 14 quantity of fastener
It is four.
Specifically, as shown in Figure 3 and Figure 4, fastener includes support portion 141 and pothook 142,141 height of support portion with
Bearing 2 is highly adapted to, 141 thinner thickness of support portion（Conducive to by bearing force feed）, pothook 142 is set on 141 top of support portion, card
Hook portion has flat bottom surface 1421 and tilts shape side surface 1422, tilts shape side surface 1422 and is arranged towards endoporus 11, tilts shape
Side surface 1422 and flat bottom surface 1421 are at an acute angle.
The setting for tilting shape side surface can guarantee that bearing is smoothly installed into endoporus, i.e., is tilted when 2 first end of bearing contacts
By fastener 14 toward 13 peripheral direction force feed of seam allowance when shape side surface 1422, after slight deformation occurs for fastener support portion 141, axis
It holds 2 to be able to smoothly cross the entrance endoporus 11 of pothook 142,2 first end of bearing is abutted with step groove 12 at this time, and the second end is
It is compressed by the flat bottom surface 1421 of pothook, the axial and circumferential action of bearing at this time is limited.
Further to promote compression effect of the fastener 14 to bearing 2, the inner surface of fastener support portion 141 be designed as with
Seam allowance inner surface structure is identical, i.e., support portion inner surface is bonded with bearing periphery, can effectively ensure that fastener to bearing
Stablize and surrounds effect.
Bearing need to be completely secured during the installation process its do not scratch, the veining defects such as bump injury, therefore tilt shape side
Surface 1422 is additionally provided with chamfering with 1421 junction of flat bottom surface and forms good transition.
As shown in Fig. 2, bearing seating face is equipped with the reinforcing rib 1 to connect with support portion, support portion can be effectively prevent
141 possibility produced fracture when slight deformation occurs.
