Abstract
The utility model discloses a bearing oil seal for a train, which comprises an outer framework, an inner framework and a rubber body which is arranged between the outer framework and the inner framework, wherein the outer framework is composed of a vertical portion and a horizontal portion, the rubber body is provided with a rubber labyrinth zone, a rubber main lip, a rubber anti-dust port and a rubber rain hood, the rubber body and the horizontal portion of the outer framework are combined to form an integrated body, the rubber rain hood is arranged under the horizontal portion of the outer framework, the rubber labyrinth zone is arranged at the end portion of a free end of the horizontal portion of the outer framework, the upper end of the rubber main lip is connected with the lower portion of the rubber labyrinth zone, the lower end of the rubber main lip is adhered with the inner framework, and the rubber anti-dust port is arranged between the rubber main lip and the rubber rain hood. With the structure, the service life can be prolonged, and the maintenance cost for trains can be lowered.
Description
Technical field
The utility model relates to a kind of bearing enclosure that is used for train.
Background technique
Train bearing is provided with the temperature rise alarm system, if frictional heat is greater than the warning temperature, system reports to the police automatically, therefore the bearing enclosure that is used for train there is the temperature rise requirement, fricative temperature is raise be lower than the warning temperature, hot box does not take place, guarantee that train normally moves, the existing bearing enclosure that is used for train exists working life shorter, needs often to change, and the maintenance cost of train is bigger.
The model utility content
Technical problem to be solved in the utility model is: a kind of bearing enclosure that is used for train is provided, and the bearing enclosure that this kind is used for train can increase the service life, and reduces the train maintenance cost.
Solve this technical problem, the technical solution of the utility model is: a kind of bearing enclosure that is used for train, it is by outer skeleton, inner frame and outer skeleton, rubber body between the inner frame is formed, outer skeleton is made up of vertical component effect and horizontal part, described rubber body has rubber labyrinth district, rubber master lip, dustproof mouthful of rubber and rubber stop canopy, described rubber body is combined into one with the horizontal part of outer skeleton, described rubber stop canopy is positioned at outer skeleton horizontal part below, described rubber labyrinth district is positioned at the free-ended end of outer skeleton horizontal part, the upper end of described rubber master lip is connected in the bottom in rubber labyrinth district, the lower end of described rubber master lip and inner frame are fitted, and the dustproof mouth of described rubber is between rubber master lip and rubber stop canopy.
The free-ended endwise skew of described outer skeleton horizontal part.
The angle that described rubber master lip and inner frame form is 22～35 degree.
The utility model is used for the bearing enclosure of train and adopts such structure, and prolonged working life, can reduce the train maintenance cost.
Description of drawings
Below in conjunction with accompanying drawing explanation is in further detail done in the bearing enclosure that the utility model is used for train;
Fig. 1 is used for the structural representation of the bearing enclosure of train for the utility model;
In Fig. 1,1, outer skeleton; 2, inner frame; 3, rubber labyrinth district; 4, rubber master lip; 5, rubber is dustproof mouthful; 6, rubber stop canopy.
Embodiment
As shown in Figure 1, the bearing enclosure that is used for train is by outer skeleton 1, inner frame 2 and outer skeleton 1, rubber body between the inner frame 2 is formed, outer skeleton 1 is made up of vertical component effect and horizontal part, rubber body has rubber labyrinth district 3, rubber master lip 4, dustproof mouthful 5 of rubber and rubber stop canopy 6, rubber body is combined into one with the horizontal part of outer skeleton 1, rubber stop canopy 6 is positioned at outer skeleton 1 horizontal part below, rubber labyrinth district 3 is positioned at the end of outer skeleton 1 horizontal part, the upper end of rubber master lip 4 is connected in the bottom in rubber labyrinth district 3, the lower end of rubber master lip 4 and inner frame 2 are fitted, and the dustproof mouth 5 of rubber is between rubber master lip 4 and rubber stop canopy 6.In order to simplify preparation process, the endwise skew of outer skeleton 1 horizontal part.In order to make rubber master lip 4 increase followability, rubber master lip 4 adopts 22～35 degree with the angle that inner frame forms.
The utility model is used for the bearing enclosure of train and adopts such structure, in the train running process, relative movement can take place in 2 of rubber master lip 4 and inner frames, 2 package powers of rubber master lip 4 and inner frame are less, fricative temperature raises can be lower than the warning temperature, hot box does not take place, and train can normally move.Because the package power of 4 pairs of inner frames 2 of rubber master lip is less, frictional force also reduces when relative movement, and wearing and tearing slow down, and prolonged working life.
