Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example 1
As shown in fig. 1-3, fig. 1 is a schematic structural diagram of a bearing outer ring of an embodiment of the present invention after outer teeth are machined, and a dotted line portion in fig. 2 is a schematic structural diagram of a toothed plate 2 mounted on an end face of the bearing outer ring 1.
A machining process for outer ring teeth of a turntable bearing comprises the following steps:
1) a toothed plate 2 is configured for the bearing outer ring 1, the shape of the toothed plate 2 is matched with that of the bearing outer ring 1, as shown in fig. 3, the toothed plate 2 in this embodiment is an arc-shaped plate, and the outer edge profile (the outer convex arc of the radial cross section) of the toothed plate 2 is matched with that (the outer circle of the radial cross section) of the bearing outer ring 1. It should be noted that the arc-shaped profile of the outer edge of the toothed plate 2 is processed according to the radius of the outer circumferential surface of the outer ring of the bearing outer ring 1, that is, the radius corresponding to the arc in the outer edge profile of the toothed plate 2 is the same as the circular diameter change in the outer edge profile of the bearing outer ring 1. The thickness, length and width of the toothed plate 2 can be set according to actual requirements. Other accuracy requirements such as the hardness of pinion rack 2 are set according to actual conditions. As long as can guarantee that processing is accomplished the back, the tooth profile of external tooth 7 on the pinion rack 2 and the external tooth 7 on the bearing inner race 1 is unanimous can.
2) Install pinion rack 2 detachable on the terminal surface of bearing inner race 1 to guarantee that the outer fringe profile of pinion rack 2 is highly unanimous with the outer fringe profile of bearing inner race 1, the pinion rack 2 of this embodiment is installed on 1 terminal surface of bearing inner race through a plurality of locating pins and a plurality of holding bolt detachable. The end face of the bearing outer ring 1 is provided with a first pin hole 4 matched with the positioning pin, the toothed plate 2 is provided with a second pin hole 5 matched with the positioning pin, the positioning pin in the embodiment is a taper pin, the positioning accuracy is high, and the disassembly and the assembly are convenient.
