The utility model discloses a sealed loaded down with trivial details degree to output shaft department is accomplished to a simple double-deck sealed form, has simplified sealed loaded down with trivial details degree, has promoted the feasibility of technology simultaneously, has solved that traditional seal structure is complicated, the problem that the change degree of difficulty is big, can satisfy the normal operating of working shafting reliably for a long time.
Description
Technical Field
The utility model relates to a seal structure, specifically speaking are shafting seal structure.
Background
The sealing performance is an important index considering the performance of the planetary reducer, and the existing sealing structure is generally a labyrinth seal structure and the like, and the structure is relatively complex.
Disclosure of Invention
An object of the utility model is to provide a double-deck seal structure that sealing performance is more excellent.
The purpose of the utility model is realized like this:
the utility model relates to a double-deck seal structure, characterized by: the oil pump comprises an inner side flange, an outer side flange, a lip-shaped sealing ring, a first oil slinger and a second oil slinger, wherein the inner side flange and the outer side flange are arranged outside an output shaft, the lip-shaped sealing ring is arranged between the inner side flange and the output shaft, and the first oil slinger and the second oil slinger are arranged between the outer side flange and the output shaft.
The utility model discloses can also include:
1. the long end of the outer flange is provided with a side surface bulge, the long end of the inner flange is attached to the long end of the outer flange, one end of the inner side of the inner flange is attached to the side surface bulge of the outer flange, the other end of the inner side of the inner flange is provided with an inner side bulge of the inner flange, and the upper end of the section of the lip-shaped sealing ring is respectively attached to the side surface bulge of the outer flange and the inner side bulge of the inner flange.
2. The flange sets up first fender oil arch and second fender oil arch with output shaft complex face in the outside, sets up first fender oil groove in the first fender oil arch, and the one end of first oil slinger is located first fender oil groove, and the other end and the output shaft cooperation of first oil slinger, the one end of second oil slinger is located second fender oil groove, and the other end and the output shaft cooperation of second oil slinger.
The utility model has the advantages that: the utility model discloses a sealed loaded down with trivial details degree to output shaft department is accomplished to a simple double-deck sealed form, has simplified sealed loaded down with trivial details degree, has promoted the feasibility of technology simultaneously, has solved that traditional seal structure is complicated, the problem that the change degree of difficulty is big, can satisfy the normal operating of working shafting reliably for a long time.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be described in more detail below by way of example with reference to the accompanying drawings:
with reference to fig. 1, the present invention is composed of an output shaft 5, a flange 2, a flange 3, a lip-shaped seal ring 4 and an oil retainer ring 1. A lip-shaped sealing ring 4 device is sleeved in a flange 3 on the outer side of an output shaft system 5, and two oil retainer rings 1 are pressed in the flange 2 simultaneously, so that a double-layer sealing effect is achieved. The inner side of the output shaft 5 is connected with a flange 3, and a lip-shaped sealing ring 4 is clamped in the flange 3. The outer side of the output shaft 5 is connected with the flange 2. Two oil slingers 1 are clamped into the inner side of the flange 2 to form a second seal for the output shaft.
Planetary reducer has very high requirement to its sealing performance, the utility model discloses an at 5 inboard flange departments of output shaft imbeds lip seal 4, lip seal 4 is sealed for the first layer of output shaft 5 department, and 2 departments imbed two oil scraper rings 1 in the outside flange of output shaft 5 again, and the effect of two oil scraper rings 1 of here is for preventing lip seal 4 under the prerequisite that can normally accomplish sealed work, and the effectual lubricating oil that flows from lip seal 4 that blocks to accomplish the sealed effect on second floor. The planetary reducer has good sealing performance while meeting the lubricating condition, and the stability and the reliability of the operation of equipment are ensured.
The utility model discloses compare with the sealed form of arranging of traditional axle head, can simplify sealed form, improve the operating stability of shafting, its reason is as follows:
1. the structure is that a lip-shaped sealing ring 4 is embedded in a flange 3 at the end of an output shaft, two oil slingers 1 are embedded in the other flange 2, and a shaft system is separated from lubricating oil in a double-layer sealing mode.
2. A first layer of sealing form is formed by the lip-shaped sealing ring 4 on the side far away from the output shaft 5, and during the operation of the output shaft 5, a layer of sealing film is formed between the lip-shaped sealing ring 4 and the output shaft 5 through rotation so as to isolate the lubricating oil from flowing out of the shaft end of the output shaft 5.
3. On one side close to the output shaft 5, through two oil slingers 1 clamped in the flange 2, a small amount of lubricating oil seeped from the lip-shaped sealing ring 4 can be effectively ensured to flow out of the shaft end of the output shaft 5, so that the double-layer sealing effect is achieved.
4. Double-deck seal structure can support work each other, even under the condition that lip seal 4 became invalid, the first layer lip seal 4 of lubricating oil outflow, follow-up oil slinger 1 can effectual prevention lubricating oil outflow 5 end departments of output shaft, and double-deck seal structure can be better satisfy planetary reducer sealing performance.
