Abstract
The utility model relates to a sealing element, in particular to an oil seal with multiple dust prevention lips and felt. The oil seal comprises a framework, a spring, a main seal lip and the dust prevention lips. The oil seal comprises at least two dust prevention lips. The felt is arranged on the end surface, close to the dust prevention lips, of the oil seal. The openings of the dust prevention lips and a rotating shaft are in interference fit, and the felt and the rotating shaft are also in interference fit. Anti-sticking points are arranged on the end surface, close to the outer circle, of the oil seal at intervals along the annular end surface. The oil seal is simple in structure, convenient to install, good in dust prevention effect and long in service life, and improves work efficiency of mechanical equipment.
Description
Technical field
The utility model relates to a kind of Sealing, and especially a kind of many dust excluder lips add felt oil seal.
Background technique
At present, the commonly used oil seal structure of machinery as shown in Figure 1, the equipment of working under rugged environment such as reaper etc. also use oil sealing as shown in Figure 1.And in actual use, owing to other impurity such as straw chip dust very easily enter in the sealing lip by the dustproof side of oil sealing, thereby cause the oil sealing leakage of oil, cause the sealing effect of oil sealing poor, and directly influenced the working efficiency of machinery.
The model utility content
The purpose of this utility model is to have proposed a kind of many dust excluder lips and adds felt oil seal, and it is simple in structure, be convenient to install, and good dustproof effect, long service life has improved the working efficiency of machinery.
The utility model is to adopt following technological scheme to realize: a kind of many dust excluder lips add felt oil seal, comprise skeleton, spring, primary seal lip and dust excluder lips, wherein, described oil sealing comprises at least two dust excluder lips, oil sealing is provided with felt near the end face of dust excluder lips, is interference fit between the lip of dust excluder lips and the running shaft, also is interference fit between felt and the running shaft, oil sealing is provided with anti-sticky point near the end face of cylindrical, and anti-sticky point arranges at interval along annular end face.
In the utility model, the annular cylindrical of described oil sealing adopts ripple struction, is convenient to the installation of oil sealing.
The beneficial effects of the utility model are: by a plurality of dust excluder lips and felt are set, avoid other impurity such as straw, chip, dust to invade the dustproof side of oil sealing effectively, improved the dustproof effect of oil sealing, prolonged the working life of oil sealing, can normally move under the abominable occasion of environment to guarantee machinery, improved the working efficiency of machinery, this oil sealing is convenient to install simultaneously, is difficult for adhesion between the oil sealing.
Description of drawings
Fig. 1 is the half sectional view of existing oil sealing;
Fig. 2 is the half sectional view of oil sealing in the utility model.
Among the figure: 1 skeleton; 2 springs; 3 dust excluder lips; 4 felts; 5 anti-sticky points.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 2 is oil sealing described in the utility model, and this oil sealing comprises skeleton 1, spring 2, primary seal lip and dust excluder lips 3, and its medi-spring 2 is arranged on the annular outboard of primary seal lip, and the elastic force of spring 2 makes primary seal lip realize axial seal.This oil sealing comprises two dust excluder lips 3, oil sealing is provided with felt 4 near the end face of dust excluder lips 3, be interference fit between the lip of dust excluder lips 3 and the running shaft, also be interference fit between felt 4 and the running shaft, felt 4 and dust excluder lips 3 have all played the dust-tight effect, to strengthen in the dustproof effect of machinery such as reaper under the abominable occasion of environment, avoid other impurity such as straw, chip, dust to invade the dustproof side of oil sealing effectively, guarantee sealing effect and the working life of oil sealing.Oil sealing is provided with anti-sticky point 5 near the end face of cylindrical, and anti-sticky point 5 arranges at interval along annular end face, inter-adhesive when preventing from depositing between the oil sealing.The annular cylindrical of oil sealing adopts ripple struction, is convenient to the installation of oil sealing.
In the utility model, dust excluder lips 3 is not limited to two in the present embodiment, also three or the dust excluder lips more than three can be set according to the need of work of reality.
Claims (2)
1. dust excluder lips adds felt oil seal more than one kind, comprise skeleton (1), spring (2), primary seal lip and dust excluder lips (3), it is characterized in that: described oil sealing comprises at least two dust excluder lips (3), oil sealing is provided with felt (4) near the end face of dust excluder lips (3), be interference fit between the lip of dust excluder lips (3) and the running shaft, also be interference fit between felt (4) and the running shaft, oil sealing is provided with anti-sticky point (5) near the end face of cylindrical, and anti-sticky point (5) arranges at interval along annular end face.
