The technical scheme has the advantages that: through set up the mounting groove that supplies the second sealing washer to place between first lasso and second lasso, and the second sealing washer can interference butt on first lasso and the second lasso, increased a seal structure between first lasso and the second lasso in other words, avoid lubricating grease to leak between two lassos, guarantee biserial tapered roller bearing's lock oily ability.
The utility model may further be arranged to: the end face of the first ferrule and the end face of the second ferrule opposite to the first ferrule are respectively provided with a first annular convex part and a second annular convex part, the first convex part can be sleeved at the inner hole of the second convex part, and the mounting groove is formed between the first convex part and the first ferrule.
Through further setting up, because first convex part and second convex part are can cup joint the complex cyclic annularly, and set up respectively on first lasso and second lasso terminal surface in opposite directions, the cross-section of first convex part and first lasso junction then presents the corner shape, set up the mounting groove in this department, move in first lasso and second lasso in opposite directions to first convex part and second convex part cup joint when joining in marriage, the second sealing washer can be compressed tightly in the mounting groove, on the one hand, can play better locate effect to the sealing washer, prevent that the second sealing washer from taking place the displacement, deviate from between first lasso and second lasso, on the other hand, with the first convex part department of second sealing washer suit, and promote to the bottom towards first lasso direction, make the second sealing washer get into mounting groove department, be convenient for the installation of second sealing washer.
The utility model may further be arranged to: first sealing washer including main part and skeleton, the cross-section of skeleton be L shape setting and including annular butt portion, butt portion wear out the main part and cooperate with the inner wall butt of outer lane, the outer lane including the guide wall that diminishes towards tapered roller direction.
Through further setting up, first sealing washer is worn out the main part by the skeleton and is annular butt portion, and the leading-in corresponding position of guide wall on the outer lane cooperates with outer lane inner wall butt, forms the location of first sealing washer, convenient assembling connects firmly.
The utility model may further be arranged to: the first sealing ring comprises a connecting part, a first sealing lip and a second sealing lip, the connecting part extends towards the tapered roller in an inclined mode, the first sealing lip and the second sealing lip are sequentially arranged towards the tapered roller, and the first sealing lip and the second sealing lip are connected to the tail end of the connecting part.
Through further setting up, set up first seal lip and second seal lip at the connecting portion terminal department that extends towards tapered roller direction slope, make the sealing washer more level and smooth in the part that exposes between outer lane and inner circle, difficult atress, and first seal lip and second seal lip can set up in corresponding butt portion department, are difficult for turning up.
The utility model may further be arranged to: the first sealing lip and the second sealing lip are arranged in a gradually-far mode towards the extending direction, and a notch is formed between the first sealing lip and the main body.
Through further arrangement, the first sealing lip and the second sealing lip are enabled to be Y-shaped, outward turning is avoided, and elasticity of the two sealing lips is guaranteed through the notch between the first sealing lip and the main body.
