Abstract
The utility model discloses a bearing device for a hollow shaft of a grinder. Two rollers are arranged in an oil tank. The hollow shaft is supported on the two rollers. The fuel tank is connected with an adjusting plate. When the hollow shaft rotate, the rollers can be driven to rotate. The friction between the hollow shaft and the roller is rolling friction. Compared with an exiting split lining babbitt metal sliding bearing device, the utility model can greatly reduce the frictional force between the hollow shaft and a bearing, reduce the friction, raise the power utilization rate of the mill, prolong the service life of the mill, and save expenses. The utility model which is suitable for ore grinding devices such as a ball grinder, a rod grinder, etc. is an ideal product for replacing the older generation of products in an enterprise.
Description
The utility model belongs to grinding attachment, relates in particular to the bearing arrangement of mill trunnion.
For a long time, the grinding attachment that ore dressing is used on various mines, as ball mill, rod mill adopts the sliding bearing of dissection type liner babbit to support quill shaft always.Such structure, when quill shaft rotated, quill shaft slided on bearing, and it is big to exist frictional force, and the mill power utilization rate is low, and quill shaft and sliding bearing are easily by the shortcoming of abrasion.Though in use can add lubricated juice in bearing, the metal surface is uneven, when parts slide relatively, still can scratch the border oil film, cause metal directly to contact, frictional force increases, and quickens the wearing and tearing of sliding surface.If can change into rolling friction to sliding friction, then can greatly reduce the frictional force of quill shaft in rotation and between bearing.
The purpose of this utility model provides a kind of mill trunnion bearing arrangement, to reduce the frictional force of quill shaft in rotation and between bearing, reduces the abrasion of quill shaft and bearing, improves the mill power utilization rate.
The purpose of this utility model can be achieved by following technological approaches, the mill trunnion bearing arrangement has fuel tank, quill shaft, quill shaft passes fuel tank front and back end plate, characteristics are to be provided with two rollers in fuel tank below the quill shaft, quill shaft is bearing on two rollers, there is roller shaft at the roller middle part, and roller shaft is bearing on the fuel tank.
From above-mentioned technical scheme as can be seen, quill shaft bearing arrangement of the present utility model is that quill shaft is bearing on two rollers, when quill shaft rotates, two rollers will rotate thereupon under the frictional force effect, and quill shaft and roller are rolling friction, compare with the existing glide bearing, can reduce frictional force greatly, reduce wear and tear in machines, save cost of use, improve the machine power utilization rate.The applicant once was the contrast experiment, φ a 1200 * 2400mm adopts the rod mill of split plain bearing need join the power of 55KW power, and is if that φ 1200 * 2400mm rod mill is the power that adopts quill shaft bearing arrangement of the present utility model only need join 30KW simultaneously; Can save 1.8 ten thousand degree electricity in one month, close 9,000 yuan of RMB, calculate with 300 days in 1 year and can save 180,000 degree electricity, close 90,000 yuan of RMB, and prolong 2 times or more than existing glide bearing the service life of equipment.Adopt quill shaft bearing arrangement of the present utility model thus, frictional resistance can reduce over half, and the supporting power of grinding machine also can reduce half.The minimizing of frictional resistance has also reduced the wearing and tearing between parts, has prolonged the service life of machine.Quill shaft of the present utility model in addition and roller all can adopt high-abrasive material to cause, and the comparable babbit of hardness is high more than 10 times.
The embodiment given below in conjunction with accompanying drawing is further described the utility model.

Fig. 7 is the structural representation of embodiment roller shaft;
Fig. 8 is the profile of Fig. 7 A-A section;
Fig. 9 is that the embodiment quill shaft is connected in the structural representation on the grinding machine.
As can be seen from Figure 1, embodiment has quill shaft (1), fuel tank (4), quill shaft passes former and later two end plates of fuel tank, in fuel tank (4), be provided with two rollers (2) below the quill shaft (1), quill shaft (1) is bearing on two rollers (2), roller (2) middle part is provided with roller shaft (3), and roller shaft (3) is bearing on the end plate of fuel tank front and back.
From Fig. 2, Fig. 3, Fig. 4 as can be seen embodiment end plate supporting rollern axle before and after the fuel tank have groove (41), the groove of end plate is connected with adjustable plate (5) with bolt before and after fuel tank, there is opening at the respective slot place on the adjustable plate, this opening is inserted in the end of roller shaft, embodiment fuel tank left and right sides end plate is provided with regulates bolt (6), this is regulated bolt (6) front end and contacts with adjustable plate (5), so that adjustable plate and roller shaft are more stable.
From Fig. 1, Fig. 5, Fig. 6 as can be seen, embodiment adjustable plate (5) is provided with projection, regulates the front end of bolt more precisely and contacts with projection on being arranged on adjustable plate.Embodiment has the open slot that allows bolt pass through on adjustable plate (5), can adjust the position of adjustable plate and roller so more easily.
From Fig. 7, Fig. 8 as can be seen, embodiment roller shaft (3) is square by the cross section of one section of fuel tank front and rear panel groove.
As can be seen from Figure 9, embodiment is provided with several oil storage apertures at quill shaft cylindrical and roller contact-segment, can improve the lubricant effect of quill shaft and roller rubbing surface.
