Abstract
The utility model discloses an oil seal for a main shaft. The oil seal for the main shaft comprises a framework and a rubber sealing body arranged on the framework in a vulcanized mode. The framework comprises a vertical framework body with the wave-shaped cross section and a horizontal framework body with the rectangular cross section. The middle of the horizontal framework body and the middle of the vertical framework body are connected into a whole. The rubber sealing body is provided with a main lip and an auxiliary lip. The main lip is sleeved with a spring; the cross section of the auxiliary lip is in a bow shape. As the framework is partially designed to be in the wave shape and the auxiliary lip is designed to be in the bow shape, the firmness of the oil seal is further enhanced on the premise of not increasing raw materials, and the oil seal for the main shaft is economical and practical.
