Abstract
The utility model relates to a bearing seat for a ball grinder, wherein a copper base alloy bearing is fixed on the upper mouth of the bearing seat, the lateral face of the bearing seat is provided with a temperature sensor which is communicated with the bearing and is provided with a convex deviation-proof pin axle, the bottom of the bearing seat is provided with two grooves, supporting blocks are arranged in the grooves, which are fixed on a core axle on the bearing base through the inner hole by a knuckle bearing, and the lower end of the supporting blocks are supported on a cushion block which is fixed on a chassis. The supporting blocks are dynamic supporting blocks whose two end faces are circular faces or static supporting blocks whose two end faces are plane bottom concave grooves. The utility model has more reasonable and compact structure, which improves the stability of running on-site of the ball grinder, improves self center regulation scope with strong automatic regulation capability, and saves the water use consumption in industry completely, and the change and the maintenance of the bearing of the ball grinder is safer.
Description
Technical field:
The utility model relates to a kind of pebble mill bearing support, is used for the fulcrum ball grinding mill barrel.
Background technique:
The structure that former pebble mill bearing support adopts is: be made up of bearing shell, bearing support, bearing cap, the lubricated cooling system that reaches.Structural volume is big, and bearing shell is wanted on-site grinding, has the movably bearing support of a dress circulating water will carry out water cooling at the scene under the bearing shell, and bearing shell needs high low pressure oil station to be lubricated system complex; Bearing axially can not move, and can only adjust automatically at both direction, and the hot cold deformation of grinding mill barrel axially can only lean on cylindrical shell to move on bearing support, moving resistance is big, weak effect, and because bearing shell adopts lead based alloy to make, the operating temperature of permission in service is low; In addition between bearing shell and the bearing support for sphere contacts, area of contact is big, is unfavorable for the grinding machine self-aligning.
Summary of the invention:
The purpose of this utility model provides a kind of pebble mill bearing support, solves the ball mill barrel big technical problem of moving resistance in the axial direction, in the four direction adjustment freely, and the water cooling plant that defaults, simplified structure.
The purpose of this utility model realizes as follows: bearing support is placed on the base, the bearing support bearing shell that is provided with suitable for reading, two grooves are arranged at the bearing support bottom, in groove, place support block, support block is supported on the mandrel that is fixed on the bearing support by its endoporus with joint shaft bearing, the support block lower end is supported on the cushion block that is fixed on the base, realizes the support of bearing support on base by support block with contacting of cushion block.By the swing of support block and moving relative to cushion block, the sphere of former pebble mill bearing support contact self-regulated core structure form, change over support block self-regulated core structure form, the hot cold deformation of grinding mill barrel axially can move axially by the moving block on the bearing support, moving resistance is little, and is effective.The water cooling of pebble mill bearing support bearing shell is designed to the lubricant oil cooling, thereby has removed the bearing shell movably bearing support of dress circulating water down, make designs simplification.
Support block is that both ends of the surface are that the moving support block of arc surface or both ends of the surface are the quiet support block of groove at the bottom of the plane.In employed 4 support blocks of two bearing supports of every table grinder, one of them selects quiet support block for use, selects moving support block for use for all the other 3.The arc surface of moving support block end face partly is supported on the plane of cushion block, and the purpose that both ends of the surface all are designed to arc surface is can reverse end for end after at one end wearing and tearing to use; Quiet support block groove is buckled on the cushion block, and the groove bottom plane is supported on the plane of cushion block, and the groove inner side surface plays position-limiting action.
There is the anti-dumping bearing pin of protrusion the bearing support side, and when bearing support too tilted, this bearing pin can touch the stop portion of base, the restriction inclination amount.
There is the temperature transducer that leads to the bearing shell place bearing support side, is used to monitor bearing bush temperature, and whether the automatic decision of equipment moves cooling mechanism.
Bearing shell is the copper base alloy bearing shell, and the operating temperature that bearing shell in service allows improves 20 ℃, has reduced the lubricating condition requirement, does not need high pressure oil lubricated, and lubrication system is simplified.
The utility model pebble mill bearing support is more reasonable on structural type, compacter; Improved the stability of the on-the-spot operation of pebble mill; Improved pebble mill from the aligning scope, automatically adjustment capability is strong; Saved the consumption of industrial water fully; Make the replacing of ball grinder bush and safeguard more convenient.
Description of drawings:
Fig. 1 is the plan view of the utility model pebble mill bearing support.
Fig. 2 is an A-A sectional view among Fig. 1.
Embodiment:
With reference to Fig. 1, Fig. 2, the bearing support 3 fixedly copper base alloy bearing shells 1 of bearing shell briquetting 2 that pass through suitable for reading, there is the temperature transducer 13 that leads to bearing shell 1 place bearing support 3 sides, there is the anti-dumping bearing pin 8 of protrusion bearing support 3 sides, two grooves are arranged at bearing support 3 bottoms, in groove, place support block 7,10, support block 7,10 are supported on the mandrel 4 with joint shaft bearing 11 by its endoporus, joint shaft bearing 11 is enclosed within mandrel 4 and fixing with positioning block 6, mandrel 4 usefulness blocks 5 are positioned on the bearing support 3, and block 5 is screwed on bearing support 3, support block 7,10 lower ends are supported on the cushion block 12, cushion block 12 is fixed on the base 9, the fuel tank of base 9 double as lubricant oil.Support block is that both ends of the surface are that the moving support block 10 of arc surface or both ends of the surface are the quiet support block 7 of groove at the bottom of the plane, in two bearing supports, 3 employed 4 support blocks of every table grinder, one of them bearing support 3 is selected a quiet support block 7 and a moving support block 10 for use, and another bearing support 3 is selected two moving support blocks 10 for use.
