ABSTRACT:
An automatic wear compensating seal device is provided for forming a seal between first and second members. An elastic sealing member is positioned between the first and second members such as that the elastic force of the sealing member holds the sealing member against at least one of the first and second members. An inclined surface is provided on the first member, the surface being inclined at acute angle with respect to the plane of sealing member. The inner peripheral surface of the sealing member contacts the first member on the inclined surface thereof to form a seal therebetween and the reaction force caused by the elastic force of the sealing member on the inclined surface holds the sealing member in contact with the second member to form a seal therebetween. Further a rotary drill bit is provided which includes the improvement of an automatic compensating seal device.
