Description
Technical field
The utility model relates to a kind of accessory of belt conveyer, is specifically related to a kind of aligning friction carrying roller on belt conveyer.
Background technology
Belt conveyer is a kind of load transfer device be widely used in the industries such as metallurgy, coal, electric power, building materials, chemical industry, traffic, light industry harbour, friction aligning carrier roller is as one of the vitals of belt conveyer, Main Function is the deviation phenomenon of correcting load-transfer device in belt conveyer operational process in time, prevent from, because belt deflection takes process not in time, causing load-transfer device and frame frictional tear, leaking and expect, even cause the grave accidents such as ruptured belt and economic loss.
The internal roller shafts of tradition aligning friction carrying roller uses key to be connected with friction shoe, and complex structure, adds assembly difficulty and fitting work amount.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, the aligning friction carrying roller providing a kind of structure simple, easy for installation.
A kind of aligning friction carrying roller, comprise roller carrier shaft, an axial end of roller carrier shaft is set with carrying roller roll body, another axial end is set with friction wheel, and friction wheel outside face is trumpet type, and portlet place is towards carrying roller roll body, large port place is provided with end cap, and roller carrier shaft inserts this end cap central; Coaxially be provided with friction shoe above described end cap, screens hoodle is installed between friction shoe and roller carrier shaft.
Described friction wheel portlet inwall is provided with and extends towards large port place, mounting blocks in column type, roller carrier shaft is through this mounting blocks, insert end cap central, the first non-contact type static seal is provided with between end cap and roller carrier shaft, the development length of mounting blocks is less than the axial height of friction wheel, the remainder of friction wheel is all in hollow state, successively axle sleeve is installed from top to bottom between mounting blocks and roller carrier shaft, bearing, back-up ring and spring fixture block, the second non-contact type static seal is arranged with outside axle sleeve, back-up ring comprises hole back-up ring and shaft block ring, hole shield ring sleeve is located at the outside face of roller carrier shaft, shaft block ring fits snugly between hole back-up ring and mounting blocks.
The end face of described friction shoe is provided with spring card slot, and be provided with spring the core of the card corresponding thereto bottom spring fixture block, Spring Card is located between above-mentioned spring card slot and spring the core of the card.
Described first non-contact type static seal and the second non-contact type static seal are Z-type rubber oil sea.
The beneficial effects of the utility model are embodied in:
1, owing to improving the connection structure of roller carrier shaft and friction shoe, installation is simplified;
2, owing to have employed hole back-up ring, door and the part such as screw for fixing door is eliminated, because this reducing installation difficulty;
3, owing to replacing the original sealing felt collar for end cap and roller carrier shaft, friction wheel and shaft room with Z-shaped rubber oil sea, because this enhancing sealing effectiveness, the service life of carrying roller is extended;
4, owing to improving friction wheel inner structure, decrease its weight, bearing radial force is reduced, increases its service life.
As mentioned above, the utility model improves the service life of aligning friction roller, productive costs is obtained and reduces greatly.
Accompanying drawing explanation
