Abstract
The utility model discloses a highly sealed protective oil seal. The highly sealed protective oil seal comprises an inner oil seal and an outer oil seal. The inner oil seal is composed of an inner seal body and an inner seal cavity, the inner seal cavity is provided with two grooves, the outer oil seal is composed of an outer seal body and an outer seal cavity, and the inner oil seal is arranged in the outer seal cavity. The highly sealed protective oil seal is reasonable in structure, light in weight, small in rotation resistance, capable of making a carrying roller flexibly rotate, good in sealing performance and effectively resistant to oil, dust and water, and the service life of the carrying roller is prolonged.
Description
Technical field
The utility model relates to a kind of high sealing protection oil sealing.
Background technology
Belt conveyer is mainly by carrying roller, support, and the compositions such as transfer drive, carrying roller is one of main composition part of belt conveyer, is most widely used.Conventional carrying roller kind has: impact idler, parallel roll, aligning carrier roller etc.The seal style of these carrying rollers mainly contains following mode:
Non-contacting seal, as axial or radial labyrinth sealing; Common contact-type sealing, as common outside framework oil seal structure.
Non-contacting seal as labyrinth sealed advantage be simple in structure, roller revolving resistance is less, but water-tight, dust-proof effect are bad, at sewage, dust, enter after carrying roller, the rapid deterioration that can cause carrying roller lubricating condition causes lubrication failure, and then cause carrying roller to damage in advance, the design life that out of reach is specified.
Common carrying roller contact of the prior art reinforced seal, is mainly comprised of inner seal ring, exterior seal ring, baffle plate etc.The inner ring of exterior seal ring adopts major and minor structure of sealing lip, and there is Compress Spring at primary seal lip place, makes the close contact of primary seal lip and roller carrier shaft by pressing force of the spring, forms contact type sealing structure.Advantage is that sealing and dustproof, waterproof effect are better.
At least there is following shortcoming in the reinforced seal of above-mentioned common carrying roller contact of the prior art:
Secondary sealing lip is too small, and gradient and elasticity are not enough, and water and pollutants still likely enter in bearing chamber.Long-term use the problems such as to exist roller revolving resistance excessive, and temperature rise is too high, lubrication failure, and then reduced the result of use of carrying roller.
Summary of the invention
The purpose of this utility model is to provide a kind of high sealing protection oil sealing.
The purpose of this utility model is achieved through the following technical solutions:
High sealing protection oil sealing of the present utility model, comprises inner oil seal, outer oil seal; Inner oil seal is comprised of interior sealing member and interior annular seal space, and interior annular seal space is provided with two grooves, and outer oil seal is comprised of outer gland sealing body and outer gland sealing chamber, and inner oil seal is located in outer gland sealing chamber.
The technical scheme being provided by above-mentioned the utility model can be found out, high sealing protection oil sealing described in the utility model, high sealing preservative oil seal structure is reasonable, quality is light, rotational resistance is little, and carrying roller rotates flexibly, good airproof performance, can actv. grease proofing, dustproof, waterproof, have extended service life of carrying roller.
Accompanying drawing explanation
Fig. 1 is high sealing preservative oil seal structure schematic diagram;
Fig. 2 is partial enlarged drawing.
The specific embodiment
High sealing of the present utility model protection oil sealing, its preferably the specific embodiment as shown in Figure 1 and Figure 2, high sealing preservative oil package is drawn together inner oil seal, outer oil seal; Inner oil seal is comprised of interior sealing member 1 and interior annular seal space 2, and interior annular seal space 2 is provided with two grooves 5, and outer oil seal is comprised of outer gland sealing body 4 and outer gland sealing chamber 3, and inner oil seal is located in outer gland sealing chamber 3.
High sealing protection oil sealing of the present utility model has following innovative point:
The interior annular seal space of high sealing protection oil sealing has two grooves, can actv. stop entering of oil, water, dust, even if the impurity such as water dust enter in groove, also can in carrying roller rotary course, utilize centnifugal force to be thrown away, actv. have extended the service life of carrying roller.
the beneficial effects of the utility model are:
Rational in infrastructure, safe and reliable;
Resistance to abrasion is strong, and quality is light;
Rotational resistance is little, and carrying roller rotates flexibly;
Good airproof performance, can actv. dustproof and waterproof, has extended the service life of carrying roller.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.
