Abstract
The invention discloses a self-lubricating bearing chamber for a crushing mill. One end of the self-lubricating bearing chamber is connected with a millstone of the crushing mill and the other end of the self-lubricating bearing chamber is connected with a dragging motor through a coupling. The self-lubricating bearing chamber mainly comprises a transmission shaft, two bearings, and a bearing pedestal shell for closing the bearings and the transmission shaft, wherein the two bearings are arranged at two ends of the transmission shaft respectively, and are also fixed on an inner wall of the bearing pedestal shell; and a cavity formed by the bearings, the transmission shaft and the bearing pedestal shell is an oil chamber. The technical scheme is that: according to the design of the bearing chamber, the airtight oil chamber is formed by the bearings, the transmission shaft and the bearing pedestal shell, machine oil is filled in the airtight oil chamber, the bearings are soaked in the machine oil, and the machine oil can fully meet the using requirements of lubrication when the bearings run at high speed; and compared with a bearing pedestal in the prior art, the self-lubricating bearing chamber has the advantage that: the fault rate caused by lubricating by using butter originally is greatly reduced.
Description
Technical field
The present invention relates to a kind of self-lubricating bearing chamber, especially a kind of self-lubricating bearing chamber that is used on the broken mill.
Background technology
The mill of broken mill is connected through between a bearing block and the dragging motor, and a bearing is arranged in this bearing block, and bearing lubrication adopts butter lubricated; Bearing block housing parcel bearing, in actual production process, the fault rate of bearing is very high; Just need to shut down maintenance in case break down; Continuity for producing is brought very adverse influence, and the bearing arrangement of taking what structure becomes the key factor that puzzlement is produced for solving the high problem of broken mill bearing fault rate.
Summary of the invention
Technical problem to be solved by this invention is the high problem of bearing block fault rate between broken mill and the dragging motor.
In order to solve the problems of the technologies described above; The present invention provides a kind of self-lubricating bearing chamber that is used on the broken mill; This self-lubricating bearing chamber one end is connected with the mill of broken mill; The other end is connected with dragging motor through shaft coupling, and said self-lubricating bearing chamber mainly is that the bearing block housing by a power transmission shaft, two bearings, airtight bearing and power transmission shaft constitutes, and said two bearings are installed in the two ends of power transmission shaft respectively; These two bearings also are fixed on the said bearing block inner walls, and cavity is a grease chamber between said bearing, power transmission shaft and the bearing block housing.
Further; Said bearing block lower housing portion is fixed on the support; A horizontal clearance guiding mechanism is arranged between this bearing block housing and the support 10, and through this horizontal clearance guiding mechanism action, this bearing block housing drives whole bearing chamber horizontal move left and right on support.
Further, said horizontal clearance guiding mechanism is a thread pitch guiding mechanism.
As a kind of preferred version, the top of said bearing block housing also has two tank filler sleeves.
As another kind of preferred version, the top of said bearing block housing also has two thermometers.
Beneficial effect of the present invention is:
1, the design of technical scheme bearing chamber of the present invention forms an airtight grease chamber between bearing, power transmission shaft and bearing chamber housing; In giving airtight grease chamber, be full of machinery oil; Bearing is soaked in the machinery oil, and when bearing ran up, machinery oil can fully satisfy lubricated the use; Compare with the prior art bearing block, reduce greatly because of the original lubricated fault rate of butter that adopts.
2, the bearing chamber of technical scheme of the present invention adopts the integral design scheme, a thread pitch guiding mechanism is installed, through the screw thread turn between bear box bottom and support; Drive whole bearing chamber integral level move left and right; Compared with prior art, the adjusting play is moved before and after original bearing outside diameter is arranged, and changes present bearing chamber integral body front and back into and regulates; Make things convenient for adjusting, also reduced the bearing chamber fault rate.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail.
Description of drawings
Fig. 1 is self-lubricating bearing of the present invention chamber and broken mill and dragging motor syndeton sketch map.
Among the figure: 1, thermometer; 2, bearing; 3, tank filler sleeve; 4, grease chamber; 5, shaft coupling; 6, horizontal clearance guiding mechanism; 7, dragging motor; 8, bearing block housing; 9, power transmission shaft; 10, support.
The specific embodiment
