Abstract
The utility model relates to a kind of castor tooth axle sleeve, comprise castor tooth sleeve body (1) and oil baffle disc (2), castor tooth sleeve body (1) install on the rotary shaft and with running shaft synchronous rotary, the external diameter of castor tooth sleeve body (1) is provided with castor tooth thread (3), oil baffle disc (2) is arranged on one end of tooth sleeve body (1), the other end contacts with the bearing inner ring of running shaft, and described oil baffle disc (2) and tooth sleeve body (1) are integrated.The utility model decreases the static seal structure between one castor tooth axle sleeve and oil baffle disc, to keep off oil, oil-collecting, oil return, lubrication bearing, sealability in one, structure is simple, good sealing effect, and can installation time be saved, be beneficial to maintenance and the replacing of sealing system.
Description
Technical field
The utility model relates to a kind of castor tooth axle sleeve.
Background technique
The motive sealing of running shaft adopts castor tooth sealing configuration usually, realizes motive sealing, the external diameter of described castor tooth axle sleeve is provided with several castor ring gears by arranging one with the castor tooth axle sleeve of running shaft synchronous rotary.Initial castor tooth sealing configuration arranges castor tooth axle sleeve on the rotary shaft, and this structure is comparatively simple, but for the larger structure of lubricating oil amount, the oil-collecting of castor tooth axle sleeve, oil return scarce capacity can cause amount of leakage large.In view of the situation, improve castor tooth axle sleeve, castor tooth axle sleeve increases an oil baffle disc, play a part to stop or the leakage of restriction lubricating oil, oil baffle disc rotates simultaneously, and being collected by lubricating oil and get rid of back bearing bore, is bearing lubrication and cooling.But connect class part or structure because oil baffle disc needs to design with castor tooth shaft room, as flange etc., oil baffle disc and castor tooth are sealed and is fixed together, to realize the two synchronous rotary, cause that existing structure is complicated, assembling difficulty, be unfavorable for maintenance and change.
Summary of the invention
The purpose of this utility model is to provide a kind of castor tooth axle sleeve, possesses the advantage that structure is simple, be easy to assembling, is beneficial to maintenance and the replacing of sealing system.
The technical solution of the utility model is, castor tooth axle sleeve comprises castor tooth sleeve body and oil baffle disc, castor tooth sleeve body install on the rotary shaft and with running shaft synchronous rotary, the external diameter of castor tooth sleeve body is provided with castor tooth thread, oil baffle disc is arranged on one end of tooth sleeve body, the other end contacts with the bearing inner ring of running shaft, and described oil baffle disc and tooth sleeve body are integrated.The side being positioned at bearing on described oil baffle disc is provided with inclined-plane.Oil trap is provided with between described castor tooth thread.
The utility model designs oil baffle disc structure before castor tooth thread sealing configuration, and castor tooth axle sleeve and oil baffle disc are integrated, Complete Synchronization during rotation.Oil baffle disc one end axially locating during assembling, oil baffle disc can stop that lubricating oil flows out, and its ramp structure is conducive to lubricating oil to get rid of to bearing bore simultaneously, plays the effect of lubrication and cooling bearing; Castor tooth axle sleeve is designed with oil trap, the lubricating oil of collection is returned bearing bore.The utility model decreases the static seal structure between one castor tooth axle sleeve and oil baffle disc, to keep off oil, oil-collecting, oil return, lubrication bearing, sealability in one, structure is simple, good sealing effect, and can installation time be saved, be beneficial to maintenance and the replacing of sealing system.
Accompanying drawing explanation
Fig. 1 is the utility model structural drawing.
