Abstract
The utility model discloses a bearing pedestal assembly for a grinding roller of a Raymond mill. The bearing pedestal assembly comprises a housing, a grinding roller shaft, an upper end cover, a lower end cover, a bearing, an O-shaped ring, framework oil seals and the like, wherein the grinding roller shaft is arranged in the through-hole of the housing via the bearing in a penetrating way; the upper end cover is mounted at the upper end of the housing; the O-shaped ring is mounted between the upper end cover and the housing; an upper framework oil seal is sleeved on the grinding roller shaft; the lower end cover is sleeved at the lower part of the grinding roller shaft; the lower end of the housing is fixedly connected with the lower end cover; a sealing felt collar is further sleeved between the lower end cover and the grinding roller shaft; a lower framework oil seal is sleeved on the grinding roller shaft at the upper part inside the lower end cover; and hoisting holes are formed on one side of the upper part of the housing. The utility model has the characteristics of simple structure and reasonable design; the bearing pedestal assembly for the grinding roller has good sealing performance; and the perfectness ratio of equipment can be extended to more than 50 days, thereby greatly reducing the downtime of equipment and maintenance cost and greatly increasing the output of grinding materials. Therefore, the bearing pedestal assembly is suitable for the installation and application in various Raymond mills.
Description
Technical field
The utility model relates to the Raymond machine bearing means, refers more particularly to a kind of Raymond machine grinding roller bearing support assembly.
Background technique
Raymond machine also is the Suspension roller milling machine.The operating environment dust of Raymond machine is big, and the Raymond machine grinding roller axle bearing stand structure that uses at present is unreasonable, and sealing is poor, very easily enters dust in the bearing.Three days left and right sides bearings are just ground badly generally speaking, and then it is eccentric to cause the wearing and tearing of grinding roller axle to occur, and grinding roller is damaged.As untimely maintenance, a whole set of parts just may be scrapped.Maintenance workload is big, and dead time is long, the maintenance expenses height, and abrasive material yields poorly.
Summary of the invention
Goal of the invention of the present utility model, being to provide a kind of can effectively overcome the problems referred to above, rational in infrastructure, good airproof performance, the Raymond machine grinding roller bearing support assembly that equipment availability is high.
The technical solution of the utility model is such, and Raymond machine grinding roller bearing support assembly comprises housing, grinding roller axle, upper end cap, lower end cap, lock nut, conical bearing, goes up O type circle, selfaligning bearing, upper skeleton oil sealing, sealing felt collar, lower skeleton oil sealing and following O type circle;
Described housing has through hole, is coated with described grinding roller axle by described conical bearing and selfaligning bearing in the described through hole; Be set with locking pad on the described grinding roller axle in described conical bearing top, a pair of described lock nut is housed on the grinding roller axle on locking pad top; Described upper end cap fixedly is equipped with by the upper end cap lock bolt in the upper end of described housing, and the described O type circle of going up is housed between upper end cap and the housing; Be set with described upper skeleton oil sealing on the described grinding roller axle in described selfaligning bearing bottom; The bottom of described grinding roller axle is set with described lower end cap, fixedlys connected with lower end cap by the lower end cap lock bolt in described housing lower end; Also be set with described sealing felt collar between described lower end cap and the described grinding roller axle; Be set with described lower skeleton oil sealing on the described grinding roller axle of described lower end cap internal upper part; Described O type circle down is housed between described lower end cap top outer rim and the described housing; One side on described housing top has lifting hole(eyelet).
Characteristics of the present utility model are: simple in structure, reasonable in design.Grinding roller bearing support assembly good seal performance, the serviceability rate of equipment can extend to more than 50 days, shortened and reduce equipment downtime and maintenance expenses greatly, and abrasive material output can be largely increased.Be fit to installing and using of various Raymond machines.
Description of drawings
Fig. 1 is a Raymond machine grinding roller bearing support assembly integral structure cross-sectional schematic;
Wherein: O type circle on 1 housing, 2 through holes, 3 grinding roller axles, 4 upper end caps, 5 lower end caps, 6 lifting hole(eyelet)s, 7 lock nuts, 8 locking pads, 9 conical bearings, 10,11 selfaligning bearings, 12 upper skeleton oil sealings, 13 sealing felt collars, 14 lower skeleton oil sealings, 15 times O type circles, 16 upper end cap lock bolts, 17 lower end cap lock bolts.
Embodiment
As shown in Figure 1, described housing 1 has through hole 2, is coated with described grinding roller axle 3 by described conical bearing 9 and selfaligning bearing 11 in the described through hole 2; Be set with locking pad 8 on the described grinding roller axle 3 in described conical bearing 9 tops, on the grinding roller axle 3 on locking pad 8 tops a pair of described lock nut 7 be housed; Described upper end cap 4 fixedly is equipped with by upper end cap lock bolt 16 in the upper end of described housing 1, and the described O type circle 10 of going up is housed between upper end cap 4 and the housing 1; Be set with described upper skeleton oil sealing 12 on the described grinding roller axle 3 in described selfaligning bearing 11 bottoms; The bottom of described grinding roller axle 3 is set with described lower end cap 5; Fixedly connected with lower end cap 5 by lower end cap lock bolt 17 in described housing 1 lower end; Also be set with described sealing felt collar 13 between described lower end cap 5 and the described grinding roller axle 3; Be set with described lower skeleton oil sealing 14 on the described grinding roller axle 3 of described lower end cap 5 internal upper parts; Described O type circle 15 down is housed between described lower end cap 5 top outer rims and the described housing 1; One side on described housing 1 top has lifting hole(eyelet) 6.
During use, if fill with the special oil plant that mixes in the through hole space between upper skeleton oil sealing and the lower skeleton oil sealing, its sealing effect can be better.
