A kind of splined with seal ring is secondary
It is secondary that the utility model relates to a kind of splined, and particularly a kind of splined with seal ring is secondary.
Existing common splined is secondary general without seal elements such as O type circle, bonded washer, sealing gaskets, also also underfill lubricating grease or lubricant oil (as shown in Figure 3) between splined shaft and spline housing.When splined pair works in muddy water, easily cause the corrosion of splined position, the sand grains in muddy water enters spline key side and causes wearing and tearing, the serious reliability reducing machinery.
Summary of the invention
It is secondary that the purpose of this utility model is to provide a kind of splined with seal ring.
The technical solution of the utility model is: a kind of splined with seal ring is secondary, it is characterized in that: be made up of splined shaft, O type circle, spline housing, sealing gasket, thrust washer, bonded washer and clamping bolt; O type circle is set in the inner unthreaded hole O type groove of spline housing, fits tightly with the optical axis portion of splined shaft; Sealing gasket, thrust washer and bonded washer is provided with in the outer end of spline housing, and by clamping bolt by bonded washer, thrust washer and sealing gasket and splined shaft and spline housing axial locking.
The utility model is full of lubricant oil or lubricating ester between spline housing and splined shaft.
The utility model is processed with O type groove in spline housing, for mounting O-shaped rings.
The utility model is provided with sealing gasket between spline housing and thrust washer.
The utility model is provided with bonded washer between clamping bolt and thrust washer.
Spline described in the utility model is rectangular spline or involute splines.
Splined pair described in the utility model is applied on the tool roller axis of rotary cultivator.
Splined pair described in the utility model is applied on the tool roller axis of change-can mixer.
The utility model is specially adapted to the machinery worked in muddy water, can effectively prevent the sand grains in muddy water from entering spline pair, substantially increases the operational safety of machinery.
Accompanying drawing explanation

Fig. 2 is the utility model structural representation;
Fig. 3 is the secondary schematic diagram of existing common splined.
In figure: 1, splined shaft; 2, O type circle; 3, spline housing; 4, sealing gasket; 5, thrust washer; 6, bonded washer; 7, clamping bolt.
A kind of splined with seal ring described in the utility model is secondary, the secondary special machinery adapting to be used for working in water or muddy water of this connection.As rotary cultivator, change-can mixer etc.
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1 and Figure 2, the right-hand member unthreaded hole of spline housing 3 is processed the O type groove of mounting O-shaped rings 2, first O type circle is placed in this groove during installation, lubricating grease or lubricant oil are smeared in the spline position of spline housing and splined shaft 1, reinstall splined shaft, now, the optical axis portion of O type circle and splined shaft fits tightly; By order illustrated, sealing gasket 4, thrust washer 5, bonded washer 6 are installed at spline axle head, then clamping bolt 7 is tightened.
