Abstract
The utility model discloses a secondary sealing structure of a pneumatic motor. The secondary sealing structure comprises a pneumatic motor shell, a supporting ring and a heat-shrinkable bushing, wherein the pneumatic motor shell is circular and comprises a middle section; two sides of the middle section are respectively a shoulder part and a tail part of the shell, and the diameters of the shoulder part and a tail part are smaller than that of the middle section; the inner diameter of the heat-shrinkable bushing is equal to or slightly greater than the diameter of the middle section; after being heated and shrunk, the heat-shrinkable bushing is tightly attached to the pneumatic motor shell and axially exceeds the shoulder part and the tail part of the shell; the supporting ring is sleeved and fixed on the shoulder part of the pneumatic motor and tightly presses the heat-shrinkable bushing at an opening of the shoulder part of the pneumatic motor shell; and an opening in the tail part of the pneumatic motor shell of the heat-shrinkable bushing is sealed by sealing glue. The pneumatic motor is secondarily sealed by the heat-shrinkable bushing and the sealing glue, so that leakage of compressed air from the motor shell can be reduced to the maximum extent; and pollution of the compressed air in the motor to the environment is reduced.
Description
Technical field
The utility model relates to a kind of pneumatic motor sealing configuration.
Background technique
Pneumatic motor is as in the Pneumatic Transmission pressure of pressurized gas being converted into mechanical energy and produces the pneumatic apparatus that rotatablely moves.In the time of its work, there is certain pressure inside, therefore, needs the pneumatic motor housing that corresponding sealability is arranged.But find in actual the use that a sealing configuration depending pneumatic motor product itself alone can't satisfy seal request fully, need carry out secondary seal, to reduce the leakage of pressurized gas from the starting motor housing parts to greatest extent.
Summary of the invention
The utility model problem to be solved provides a kind of pneumatic motor secondary seal structure that pressurized gas leaks at the pneumatic motor housing parts that reduces to greatest extent.
The technological scheme that the utility model adopted is: pneumatic motor secondary seal structure comprises pneumatic motor housing, support ring, heat-shrinkable T bush; Said pneumatic motor housing is rounded; Comprise intermediate section; Said intermediate section both sides are to be respectively housing shoulder and the afterbody of diameter less than the intermediate section diameter; Said heat-shrinkable T bush internal diameter equals or is slightly larger than the intermediate section diameter, closely pastes to obey in said pneumatic motor housing after the said heat-shrinkable T bush heat shrink also axially to exceed its shoulder and afterbody, and said support ring suit is fixed in the pneumatic motor shoulder; And pressing the opening of heat-shrinkable T bush in pneumatic motor housing shoulder from the side, the pneumatic motor housing afterbody opening of heat-shrinkable T bush is realized sealing by sealer.
In the such scheme, preferred said support ring is realized fixing in the locking hole of pneumatic motor shoulder through holding out against screw lock.
The beneficial effect of the utility model is: the utility model carries out secondary seal through adopting thermoplastic sleeve pipe and sealer to pneumatic motor; Can reduce the leakage of pressurized gas to greatest extent, reduce of the pollution of the interior pressurized gas of motor environment in the motor casing part.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the decomposition texture schematic representation of the utility model embodiment;
Fig. 2 is the package assembly schematic representation of the utility model embodiment.
Embodiment
Like Fig. 1, shown in Figure 2; In the utility model embodiment, pneumatic motor secondary seal structure comprises pneumatic motor housing 1, support ring 2, heat-shrinkable T bush 3, and pneumatic motor housing 1 is rounded; Comprise intermediate section 11; Said intermediate section both sides are to be respectively the housing shoulder 12 and afterbody 13 of diameter less than the intermediate section diameter, and heat-shrinkable T bush 3 internal diameters equal or are slightly larger than intermediate section 11 diameters, closely paste after heat-shrinkable T bush 3 heat shrink to obey in pneumatic motor housing 1 also axially to exceed its shoulder 12 and afterbody 13; Support ring 2 is set on the pneumatic motor shoulder 4, and two tapped holes 21 that are positioned on the same diameter are arranged on it.The inner ring of supporting frame 2 cooperates with pneumatic motor shoulder 4; Through hold out against screw 22 be locked to realize in the locking hole 41 of pneumatic motor shoulder 4 fixing; And pressing the opening of heat-shrinkable T bush 3 in pneumatic motor housing shoulder 12 from the side, the pneumatic motor housing afterbody opening of heat-shrinkable T bush 3 is realized sealing by sealer 5.
Above embodiment has been carried out detailed explanation to the utility model, but these are not the restriction of formation to the utility model.The protection domain of the utility model does not exceed with above-mentioned mode of execution, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (2)
1. pneumatic motor secondary seal structure; It is characterized in that: said pneumatic motor secondary seal structure comprises pneumatic motor housing, support ring, heat-shrinkable T bush; Said pneumatic motor housing is rounded; Comprise intermediate section, said intermediate section both sides are to be respectively housing shoulder and the afterbody of diameter less than the intermediate section diameter, and said heat-shrinkable T bush internal diameter equals or is slightly larger than the intermediate section diameter; Closely paste after the said heat-shrinkable T bush heat shrink to obey and also axially exceed its shoulder and afterbody in said pneumatic motor housing; Said support ring suit is fixed in the pneumatic motor shoulder, and presses the opening of heat-shrinkable T bush in pneumatic motor housing shoulder from the side, and the pneumatic motor housing afterbody opening of heat-shrinkable T bush is realized sealing by sealer.
2. pneumatic motor secondary seal structure according to claim 1 is characterized in that: said support ring is realized in the locking hole of pneumatic motor shoulder fixing through holding out against screw lock.
