Abstract
The utility model relates to a contact double-lip sealed structure, mainly comprising a frame and a sealed rubber which forms an inner block lip and an outer block lip at the end of two sides. The utility model is provided with an inner sealed lip and an outer sealed lip matched with an inner ring V shape sealed groove. The contact double-lip structure is composed the inner sealed lip and the outer sealed lip. A groove is arranged between the inner sealed lip and the inner block lip, and a flute is arranged between the outer sealed lip and the outer block lip. The inner sealed lip and the outer sealed lip are distributed equally, and appears a converted V shape. The good effect of the utility model is that the utility model can effectively prevent the intrusion of sundries and make the lubricant flow in. The lubrication of the bearing basically relies on the gear oil flowing in through the sealed lip, thereby ensuring the bearing lubricating capacity.
Description
Technical field
The utility model relates to the sealing configuration field, especially with the matching used a kind of contact-type double-lip seal structure of gearbox bearing.
Background technique
Loaded-up condition according to motor, during thrust load that gearbox replaces about axially producing with gear, bearing inner race is also along with this load is done atomic little moving to the left and right, the contact position of common sealing lip structure is outside when mobile under such Axial Loads, just may have foreign material and invade.The lubricant oil that generally can not make of common sealing configuration flows into, and the lubricated of bearing is not to rely on the gear oil that flows into by sealing lip basically.
Summary of the invention
The purpose of this utility model is to provide a kind of foreign material that prevent to invade the contact-type double-lip seal structure that lubricant oil is flowed into.
The technological scheme that its technical problem that solves the utility model adopts.This contact-type double-lip seal structure, mainly comprise skeleton and caulking gum, caulking gum both-side ends form the inner retaining side lip and outside the rib lip, be provided with the interior sealing lip and the outer seal lip that can match with inner ring V-seal groove, constitute contact-type lips structure by interior sealing lip and outer seal lip.
Be provided with a groove between interior sealing lip and the inner retaining side lip, be provided with a groove between outer seal lip and the outer rib lip.Sealing lip and outer seal lip are symmetrically distributed in described, and are inverted V-shape.
The effect that the utility model is useful is: 1, contact-type double-lip seal structure is according to the design of the particular service requirement of gearbox, its sealing lip is a contact-type, and be lips, can be pressed in the inner ring V-seal groove, the seal ring slip moment of design is lower, the increase of bearing frictional torque can be controlled at inferior limit.2, according to the loaded-up condition of motor, during thrust load that gearbox replaces about axially producing with gear, bearing inner race is also along with this load is done atomic little moving to the left and right, the contact position of sealing lip is outside when mobile under such Axial Loads, another sealing lip that separates will be near the oppose side wall of inner ring seal groove, thereby prevents that foreign material from invading.3, the lubricant oil that can make on the other hand of this sealing configuration flows into, and the lubricating grease that compatibility is arranged of Zhu Ruing only plays lubrication in the early stage in advance, and the lubricated of bearing is to rely on the gear oil that flows into by sealing lip basically, thereby guaranteed the greasy property of bearing.
Description of drawings
Fig. 1 is a main TV structure schematic representation of the present utility model;
Embodiment
Below in conjunction with embodiment the utility model is further described.As shown in the figure, this contact-type double-lip seal structure, mainly comprise skeleton 1 and caulking gum 2, caulking gum 2 both-side ends form inner retaining side lip 2-3 and outside rib lip 2-4, be provided with the interior sealing lip 2-1 and the outer seal lip 2-2 that can match with inner ring V-seal groove, interior sealing lip 2-1 and outer seal lip 2-2 are symmetrically distributed, and are inverted V-shape.Constitute contact-type lips structure by interior sealing lip 2-1 and outer seal lip 2-2.Be provided with a groove 3 between interior sealing lip 2-1 and the inner retaining side lip 2-3, be provided with a groove 4 between outer seal lip 2-2 and the outer rib lip 2-4, the lubricated of bearing is to rely on the gear oil that flows into by sealing lip basically, thereby guaranteed the greasy property of bearing.
