Embodiment Construction

[0018] In order to further illustrate the technical means and effects of the present invention to achieve the above objectives, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described in the present invention are only used to explain the present invention, and are not intended to limit the present invention.

[0019] Such as Figure 1 to Figure 3 The new dust-tight oil seal of the embodiment of the present invention shown is composed of a Teflon sealing lip 1 and an oil seal frame 2. The oil seal frame 2 is in the shape of a ring, and one end surface of the oil seal frame 2 is provided with a plurality of disassembly holes 3. An annular groove is arranged on the inner ring hole surface of the oil seal frame 2, and a Teflon sealing lip 1 is arranged in the annular groove.

[0020] Such as figure 2 As sh...

Abstract

The invention relates to the technical field of explosion-proof motors, in particular to a novel dust-tight oil seal which is composed of a Teflon sealing lip and an oil seal frame, the oil seal frame is in a circular ring shape, one end face of the oil seal frame is provided with a plurality of dismounting holes, the inner ring hole face of the oil seal frame is provided with an annular groove, and the Teflon sealing lip is arranged in the annular groove. The novel dust-tight oil seal is simple in structure, convenient to mount and dismount, high in material inheritance degree, high in universality and high in sealing protection level.

Description

technical field [0001] The invention relates to the technical field of mechanical rotating equipment with dust-proof and waterproof combined seals, where the working medium is oil, water, air and dust and meets the requirements of dust-tightness; in particular, it relates to a novel dust-tight oil seal. Background technique [0002] In recent years, the explosion-proof motor industry has developed rapidly, the output has continued to increase, and the quality has been steadily improved. However, the oil seal used in this type of motor is often required to be replaced due to the poor working environment of the motor. If the motor manufacturer adopts a conventional sealing method, the sealing effect is not good. The conventional sealing methods are: [0003] 1. The V-shaped sealing ring structure is conventionally adopted, and the dustproof and waterproof can not reach IP66; [0004] 2. The skeleton oil seal structure is conventionally used, and the mechanical loss is relativ...
