Abstract
The utility model discloses a wheel carrier structure, which comprises a wheel carrier. A pin shaft is fixed on the wheel carrier, a wheel disc is mounted on the pin shaft, a bearing is arranged between the wheel disc and the pin shaft, the pin shaft is a stepped shaft with a tapered diameter, a step at the major diameter end of the pin shaft presses against the bearing, and the minor diameter end of the pin shaft is in key joint with the wheel carrier and fixed on the wheel carrier through nuts. According to the wheel carrier structure, a key groove is arranged on the pin shaft, a key groove part corresponding to the key groove is mounted on the wheel carrier and used for assembly, the pin shaft and the wheel carrier are locked through keys so that the phenomenon of slipping is avoided, thread structures are arranged at the end of the shaft, the pin shaft is locked by the two nuts arranged on the thread structure, and the two nuts can be used for locking the wheel carrier structure, eliminating the gap between the wheel disc and the wheel carrier, and solving the problem that the pin shaft is loosened when the wheel disc rotates at a high speed.
Description
Technical field
The utility model relates to the spinning wheel wheel carrier.
Background technology
Spinning is to be used to be shaped a kind of stress metal processing method of thin-walled hollow revolving body workpieces; It is to do feed motion by instruments such as spinning rollers; Stress on the metal blank of core, make its continuous local plastic deformation of generation and become required hollow revolving body workpieces along same axis rotation.Along with development of high-tech; Also increasingly high to requirement of products; Some technologies such as low pressure casting, gravitational casting or the like have satisfied not requirement of client, and spinning process also receives much concern, even has entered into some high-end enterprises; Spinning process has its superiority, and is also increasingly high for the requirement of equipment.The problem that existing spinning wheel carrier exists is exactly a wheel disc when rotating at a high speed, and bearing pin is loosening easily.
The utility model content
The utility model technical problem to be solved just provides a kind of wheel carrier structure, the loosening problem of bearing pin when the elimination wheel disc rotates at a high speed.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of wheel carrier structure comprises wheel carrier; A fixing bearing pin on the said wheel carrier; Said bearing pin is provided with wheel disc, is provided with bearing between wheel disc and bearing pin, it is characterized in that: said bearing pin is the multidiameter that diameter diminishes gradually; Also be anchored on the wheel carrier when key is connected between the step roof pressure bearing of bearing pin bigger diameter end, bearing pin miner diameter end and wheel carrier through nut.
As preferably, the said bearing outside is by the gland roof pressure, and said gland excircle is provided with protruding bulge loop to said bearing outer ring, said bulge loop roof pressure bearing outer ring.
As preferably, be provided with pad between the said gland outside and wheel carrier.
The bearing pin of the utility model is provided with a keyway, on wheel carrier, is provided with the keyway parts corresponding with this keyway, is used for assembling and uses; Through key that bearing pin and wheel carrier is locked, skidding can not appear, be provided with helicitic texture in the end of axle; Be provided with two nuts above bearing pin is locked,, not only can be used for self-locking through the effect of two nuts; Simultaneously can also eliminate the gap between wheel disc and the wheel carrier, the loosening problem of bearing pin when the elimination wheel disc rotates at a high speed.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the pin shaft structure sketch map;
Fig. 3 is a bearing pin keyway place position cutaway view;
Fig. 4 is the gland sketch map.
The specific embodiment
To shown in Figure 4, be the embodiment of a kind of wheel carrier structure of the utility model like Fig. 1, comprise wheel carrier 1; A fixing bearing pin 2 on the said wheel carrier; Said bearing pin is provided with wheel disc 3, is provided with bearing 4 between wheel disc and bearing pin, and said bearing pin is the multidiameter that diameter diminishes gradually; Also be anchored on the wheel carrier when key is connected between the step roof pressure bearing of bearing pin bigger diameter end, bearing pin miner diameter end and wheel carrier through nut 7.The said bearing outside is by gland 5 roof pressures, and said gland excircle is provided with protruding bulge loop 51 to said bearing outer ring, said bulge loop roof pressure bearing outer ring.Be provided with pad 6 between the said gland outside and wheel carrier.Said nut is provided with two.
