Abstract
The utility model discloses a pneumatic motor for a mine escape capsule or a refuse chamber. The pneumatic motor comprises a shell, an end cover, a driving shaft, a sliding bearing and a bearing seat, wherein the end cover is connected with the shell, the driving shaft is arranged in the shell, the sliding bearing is sleeved on the outer wall of the driving shaft, the bearing seat is sleeved on the outer side of the sliding bearing, a seal rubber sleeve is sleeved at a sleeving part of the top end of the bearing seat and the sliding bearing, and a connection part of the shell and the end cover, a part between the end cover and the bearing seat, and parts on two sides of the sliding bearing in the bearing seat are respectively provided with a seal ring. The pneumatic motor disclosed by the utility model can ensure the airtightness within 300 hours without leakage when implementing rescue underground, thus largely prolonging the service life and ensuring the personal safety of users.
Description
Technical field
The utility model relates to a kind of pneumatic motor, and specifically mining rescue capsule or refuge chamber are used pneumatic motor.
Background technique
As the mining rescue capsule or the refuge chamber of underground emergency avoiding system, should keep that (or indoor) aerial temperature and humidity level is in the acceptable scope by the rescue personnel in the cabin, this often realizes through the pressurized gas swell refrigeration.In order to reduce the use of emergency power, the air circulation of (or indoor) can realize through utilizing mesolow gas-powered pneumatic motor and blower fan behind the swell refrigeration in the cabin.It is energy conversion efficiency and technical orders such as noise, life-span that conventional pneumatic motor major technology requires, not high to the requirement of sealability, as long as it is just passable to leak the utilization ratio of not appreciable impact energy.But for the pneumatic motor that uses in mining rescue capsule or the refuge chamber, such requirement is enough inabundant.Often can be as carbon dioxide because be used for the gas of swell refrigeration by the refrigerant of normal-temperature liquefaction; If leak into (or indoor) in the cabin; Must strengthen the load of (or indoor) air cleaning system in the cabin, can have influence on by rescue personnel's health and lives when serious.Therefore, the pneumatic motor of conventional structure can not use simply the air-conditioning of mining rescue capsule or refuge chamber with purify on the blower fan, must be in addition technological improvement and the raising of its sealing.
The model utility content
The purpose of the utility model is the deficiency that exists to existing technology, provides a kind of good seal performance, mining rescue capsule or refuge chamber that Safety performance is high to use pneumatic motor.
For realizing above-mentioned model utility purpose; The technological scheme that the utility model adopts is that a kind of mining rescue capsule or refuge chamber are used pneumatic motor; The end cap that comprises housing, joins with housing, be installed in the transmission shaft in the housing, the bearing support that is sleeved on the sliding bearing of transmission shaft outer wall and is sleeved on the sliding bearing outside; Top and sliding bearing socket place at bearing support are set with seal rubber sleeve, and the both sides of sliding bearing are equipped with seal ring between connecting part, end cap and the bearing support of housing and end cap and in the bearing support.
The outside of said sliding bearing also is set with rotor, stator, and the afterbody of sliding bearing is set with rolling bearing, between housing and stator, is provided with sealing gasket.
The two-fold seal ring adds that triple motive sealings that a resealing gum cover constitutes can guarantee that motor pressure inside gas can not leak because of the rotation of transmission shaft.For guaranteeing the static seal property of pneumatic motor, between stator and shell, sealing gasket is installed, between shell and end cap, bearing support and end cap, seal ring is installed also.
Beneficial effect: this pneumatic motor that the utility model provides all can guarantee the sealing of gas in 300 hours of down-hole enforcement rescue, do not have and leak, and has prolonged working life greatly, has ensured user of service's personal safety.
Description of drawings
Fig. 1 the utility model structural representation; 12 is air flues among the figure, the 13rd, and slide plate.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model, present embodiment is being to implement under the prerequisite with the utility model technological scheme, should understand these embodiments only be used to the utility model is described and be not used in the restriction the utility model scope.
As shown in Figure 1, the utility model comprises housing 1, stator 9, rotor 8, transmission shaft 3, bearing support 5, end cap 2 etc.On housing 1 and stator 9, be processed with screw and the air flue 12 that gas air inlet and air outlet adapter are installed, rolling bearing 10 is installed on the stator, slide plate 13 is installed on the rotor 8, rotor 8 is installed in the stator 9.One end of transmission shaft 3 is installed in sliding bearing 4 and the rotor 8, and the other end of transmission shaft 3 stretches out end cap 2 after through bearing support 5 and connects outside blower fan.Sliding bearing 4 two sides respectively are equipped with sealing O type circle 7 one in the bearing support 5, and bearing support 5 also is equipped with axial seal gum cover 6 one near the blower fan side.Between housing 1 and the stator 9 sealing gasket 11 is installed, seals O type circle 11 also being equipped with between housing 1 and the end cap 2 to be equipped with between sealing O type circle 11, bearing support 5 and the end cap 2.
Above-mentioned pneumatic motor is when normal operation, and mesolow gas gets into housing 1 and stator 9 through suction port and air flue 12, and gas-powered rotor 8 running backs reduce pressure, flows out deliver from vault outer (outdoor) side by side through stator 9 and air outlet channel and air outlet 12 on the housing 1 again.Above-mentioned rotor 8 drives transmission shaft 3, the outside blower fan running of transmission shaft 3 drives, drives (or indoor) air flow in the cabin thereby accomplish, and satisfies the air-conditioning and purification needs of rescue capsule or lifesaving chamber.
The utility model pneumatic motor all can guarantee the sealing of gas in 300 hours of down-hole enforcement rescue, do not have and leak.Using perhaps running to use through rescue surpasses 300 hours occasion, needs the replacing pneumatic motor.
