Abstract
The utility model relates to an air throttle bearing with axial chamfer positioning. An axial chamfer is arranged at the end of the bearing and has an inclined segment and a circular arc segment. The inclined segment has an axially reducing inclined plane, the front end of the inclined plane is connected with the horizontal plane at the end of the bearing, and the rear end of the inclined plane is connected with the circular arc plane of the circular arc segment. When being assembled on an air throttle casing, the air throttle bearing can well guide the insertion and pullout of an assembly shaft, after the bearing is pressed into the air throttle casing, due to the guide action of the inclined plane at the end, the bearing is not easy to be stuck on the assembly shaft, and the air throttle casing is easy to fall off from the assembly shaft, so as to increase the assembly speed of the air throttle casing.
Description
Technical field
The utility model relates to the technical field of closure bearing, the closure bearing of especially a kind of axial chamfering location.
Background technique
In the closure housing of automobile, a fan-shaped axle passes two closure bearings simultaneously, slowly run, and then the unlatching and the closure of control closure.The end of conventional closure bearing is single rounding, like this, when the automatic production line assembling throttle plate pin of closure housing holds, after bearing is pressed into the closure housing, two bearings are stuck on assembled shaft easily, housing can not freely come off on assembled shaft, influences the installation rate of closure housing.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, the closure bearing of a kind of axial chamfering location is provided, bearing is difficult for stuckly on assembled shaft when making the assembling of closure housing, improves the assembling speed of closure housing.
The technological scheme that its technical problem that solves the utility model adopts is: the closure bearing of a kind of axial chamfering location, and the bearing end has axial chamfering, and described axial chamfering has bevel phase and arc section, and bevel phase has the inclined-plane of axial reducing.Described axial chamfering all can be provided with in the bearing both side ends, further improves the escape velocity of assembled shaft and bearing.
Further, the horizontal plane of described inclined-plane front end and bearing end joins, and the arc surface of rear end, inclined-plane and arc section joins.
Further, the axial length of described axial chamfering is 0.9mm, and the axial length of described arc section is 0.39mm, and the angle of described inclined-plane and horizontal plane is 9.8 °.
The beneficial effects of the utility model are: bearing of the present utility model end has the axial chamfering on band inclined-plane, therefore, when being assemblied in the utility model on the closure housing, can guide the insertion and the extraction of assembled shaft preferably, after bearing was pressed into the closure housing, because of the guiding function of end chamfer, bearing was difficult for stuck on assembled shaft, the closure housing comes off from assembled shaft easily, has improved the assembling speed of closure housing.The utility model is simple in structure, good positioning effect, improved the efficient and the closure housing assembly quality of closure automatic assembly line effectively.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged diagram at A place among Fig. 1;
Wherein: 1. bevel phase, 2. arc section.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Closure bearing as Fig. 1 axial chamfering location shown in Figure 2, the bearing end has axial chamfering, and axially chamfering has bevel phase 1 and arc section 2, and bevel phase 1 has the inclined-plane of axial reducing, the horizontal plane of inclined-plane front end and bearing end joins, and the arc surface of rear end, inclined-plane and arc section 2 joins.Axially the axial length of chamfering is 0.9mm, and the axial length of arc section 2 is 0.39mm, and the angle of inclined-plane and horizontal plane is 9.8 °.
When being assemblied in the utility model on the closure housing, after bearing was pressed into the closure housing, because of the guiding function of end chamfer, bearing was difficult for stuck on assembled shaft, and the closure housing comes off from assembled shaft easily, has improved the assembling speed of closure housing.
