Abstract
The utility model relates to a pin-lift car regulating device, which comprises a frame, a hollow shaft, a tapered roller bearing, a plane thrust bearing and an aligning roller bearing, wherein the hollow shaft is arranged in the frame. The plane thrust bearing is arranged in the middle of the hollow shaft, the aligning roller bearing is arranged at the front end of the hollow shaft, and the tapered roller bearing is arranged at the tail end of the hollow shaft. Another aligning roller bearing is additionally arranged in the pin-lift car regulating device and is mounted in front of the tapered roller bearing at the tail end of the hollow shaft. By the aid of the aligning roller bearing added at the tail end of a pin-lift car, the problem that the plane thrust bearing is out of vertical in stress due to shaking of the pin-lift car during hole punching is avoided effectively, and the service life of the pin-lift car is prolonged.
Description
Technical field
The utility model relates to a kind of ejector rob trolley provided adjusting device.
Background technology
In the prior art, in punch ejector rob trolley provided three bearings are arranged, comprise taper roll bearing, plain thrust bearing and self-aligning roller bearing.Bear bigger axial force because when perforation be ejector rob trolley provided, add that the dolly shake is severe, plain thrust bearing is often bad.
Summary of the invention
At above-mentioned shortcoming, the utility model technical issues that need to address provide a kind of ejector rob trolley provided adjusting device.
The technical solution adopted in the utility model is:
Ejector rob trolley provided adjusting device, comprise vehicle frame, be built in hollow shaft, taper roll bearing, plain thrust bearing and self-aligning roller bearing in the vehicle frame, described hollow shaft middle part is provided with plain thrust bearing, described hollow shaft front end is provided with self-aligning roller bearing, described hollow shaft end is provided with taper roll bearing, the self-aligning roller bearing that also comprises increase, the self-aligning roller bearing of described increase is placed in the place ahead of hollow the tip of the axis taper roll bearing.
The utility model has the advantages that: the self-aligning roller bearing that the end of dolly increases, the dolly shake causes the stressed out of plumb of plain thrust bearing when effectively preventing to bore a hole, and has prolonged ejector rob trolley provided service life.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, taper roll bearing, 2, the self-aligning roller bearing that increases, 3, vehicle frame, 4, plain thrust bearing, 5, hollow shaft, 6, self-aligning roller bearing.
The specific embodiment
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
As shown in Figure 1, the ejector rob trolley provided adjusting device of the utility model, comprise vehicle frame, be built in hollow shaft 5, taper roll bearing 1, plain thrust bearing 4, self-aligning roller bearing 6 in the vehicle frame and the self-aligning roller bearing 2 that increases, hollow shaft 5 middle parts are provided with plain thrust bearing 4, hollow shaft 5 front ends are provided with self-aligning roller bearing 6, hollow shaft 5 ends are provided with taper roll bearing 1, and the self-aligning roller bearing 2 of increase is placed in the place ahead of the terminal taper roll bearing 1 of hollow shaft 5.The terminal self-aligning roller bearing 2 that increases of dolly, the dolly shake causes the stressed out of plumb of plain thrust bearing when effectively preventing to bore a hole, and has prolonged ejector rob trolley provided service life.
