Abstract
The utility mode relates to a sealing member, particularly a combined oil seal, which comprises an oil seal body. The oil seal body comprises a spring and a main sealing lip. The combined oil seal also comprises a shaft sleeve and the shaft sleeve is arranged on the annular inner surface of the oil seal body. The lip of the main sealing lip is in interference fit for the outer surface of the shaft sleeve. The combined oil seal is simple in structure and convenient in installation. By utilizing the combined oil seal, the requirement for the processing precision of rotating shafts is lowered and the processing procedure of rotating shafts is simplified. Meanwhile, the production cost is saved.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of combination oil seal.
Background technique
At present, oil sealing generally directly is installed on the axle surface, and as shown in Figure 1, oil sealing is realized the effect of sealing lubricating oil by the interference fit of its sealing lip and running shaft.In order to reduce the friction between oil sealing and the running shaft, guarantee the oil sealing proper functioning, the required precision on running shaft surface and processing request are than higher.But in practical work process, some running shaft surface Machining difficulty is big; In addition, oil sealing assembling position processing request height only on the running shaft if whole running shaft carried out high-precision processing, can cause difficulty of processing big, and the cost height has caused waste to the man power and material.
The model utility content
The purpose of this utility model is to have proposed a kind of combination oil seal, and it is simple in structure, and is easy for installation, reduced the requirement on machining accuracy of running shaft, reduced the manufacturing procedure of running shaft, saves production cost.
The utility model is to adopt following technological scheme to realize: a kind of combination oil seal, comprise the oil sealing body, the oil sealing body comprises spring and primary seal lip, wherein, described combination oil seal also comprises axle sleeve, axle sleeve is arranged on the annular inner surface of oil sealing body, and the lip and the sleeve outer surface of primary seal lip are interference fit.
The beneficial effects of the utility model are: by internal surface axle sleeve are set, can reduce the requirement on machining accuracy of running shaft, reduce the manufacturing procedure of running shaft, saved cost of production, and this oil seal structure is simple at the oil sealing body, and easy for installation.
Description of drawings
Fig. 1 is the assembly structure schematic representation of oil sealing and running shaft in the prior art;
Fig. 2 is the assembly structure schematic representation of oil sealing and running shaft in the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 2 is a combination oil seal described in the utility model.This oil sealing is made up of oil sealing body 4 and axle sleeve 2, and axle sleeve 2 is arranged on the annular inner surface of oil sealing body 4.Oil sealing body 4 comprises spring and primary seal lip 3, spring is positioned at the outside of primary seal lip 3, the tension force of spring makes the lip of primary seal lip 3 and axle sleeve 2 outer surfaces be interference fit for primary seal lip 3 provides radial force, thereby realized being connected of oil sealing body 4 and axle sleeve 2.Axle sleeve 2 is enclosed within on the running shaft 1 by interference fit.By lip place axle sleeve 2 is set, has reduced the requirement on machining accuracy of running shaft, reduce the manufacturing procedure of running shaft, save production cost at the oil sealing body.
