The utility model relates to a high low temperature test case transmission shaft connecting hole sealing device wraps up the transmission shaft in high low temperature test case, has completely cut off the air flow and the heat exchange, does not influence motor and transmission shaft rotation simultaneously, and the temperature accuracy when having promoted high low temperature test greatly has eliminated the potential safety hazard because of the transmission shaft rotation brings, convenient operation, and is with low costs, safe and reliable.
Description
Technical Field
The utility model belongs to the technical field of commercial car derailleur test bench, concretely relates to sealing device between high low temperature test case and motor drive axle, in particular to high low temperature test case transmission shaft connecting hole sealing device, the occasion of connecting the motor need rotate when mainly being applied to the high low temperature test of derailleur.
Background
The high-low temperature test box is common test equipment in a bench test, a motor needs to be connected when a transmission test is carried out, but the motor is in a normal temperature environment, and therefore a sealing device is needed to prevent the high-low temperature test box from excessively influencing the temperature in the high-low temperature test box due to heat exchange with the outside. At present, the connection hole of a transmission shaft on a domestic high-low temperature test box is sealed by a brush or a filler, so that heat exchange between the high-low temperature test box and the outside is reduced. The sealing method has poor sealing effect, can not effectively isolate the outside air, and has certain potential safety hazard because the brush or the filler is contacted with the transmission shaft.
Disclosure of Invention
The utility model aims at providing a high low temperature test case transmission shaft connecting hole sealing device just lies in to the not enough of above-mentioned prior art, and the device can seal the transmission shaft in the temperature environment of high low temperature test case to isolated motor and outside air, isolated high low temperature test case and outside air flow reduce the heat exchange. Meanwhile, the device is not in contact with the transmission shaft, potential safety hazards are eliminated, the operation is convenient, the safety and the reliability are high, the function of a protective cover can be achieved, and external articles are protected.
The utility model aims at realizing through the following technical scheme:
the utility model provides a high low temperature test box transmission shaft connecting hole sealing device which characterized in that: the corrugated pipe heat-preservation box is composed of a connecting plate I1, a clamping device I2, heat-preservation cotton 3, a corrugated pipe 4, a clamping device II 5, a connecting plate II 6, a high-low temperature box 7, a motor 8 and a transmission shaft 9.
The connecting plate I1 and the connecting plate II 6 are respectively fixed on the high-low temperature box 7 and the motor 8 through fastening bolts.
The transmission shaft 9 is arranged on the motor 8, and the corrugated pipe 4 with the heat preservation cotton 3 is sleeved outside the transmission shaft 9. The heat preservation cotton 3 is installed on the inner wall of the corrugated pipe 4, the length of the heat preservation cotton 3 is equivalent to that of the corrugated pipe 4, and the heat preservation cotton is prevented from excessively deforming to interfere with a transmission shaft. Bellows 4 links to each other with high low temperature case 7 and motor 8, just clamping device I2, clamping device II 5 press from both sides tight bellows 4 and high low temperature case 7 junction and bellows 4 and motor 8 junction respectively, form a confined cavity like this, wrap up the transmission shaft at high low temperature test box inboard, have isolated motor and other objects simultaneously.
The clamping device I2 and the clamping device II 5 can be universal and are used for clamping after the transmission shaft 9 is connected.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model relates to a high low temperature test case transmission shaft connecting hole sealing device wraps up the transmission shaft in high low temperature test case, has completely cut off the air flow and the heat exchange, does not influence motor and transmission shaft rotation simultaneously, and the temperature accuracy when having promoted high low temperature test greatly has eliminated the potential safety hazard because of the transmission shaft rotation brings, convenient operation, and is with low costs, safe and reliable.
Drawings
The invention will be further described with reference to the accompanying drawings:
fig. 1 is a schematic view of the whole structure of the sealing device for the connecting hole of the transmission shaft of the high-low temperature test chamber of the utility model;
fig. 2 is an effect schematic diagram of the utility model discloses be connected with high low temperature test box and motor during the use.
In the figure: 1. the connecting plate I2, the clamping device I3, the heat preservation cotton 4, the corrugated pipe 5, the clamping device II 6, the connecting plate II 7, the high-low temperature box 8, the motor 9 and the transmission shaft.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making more clear and definite definitions of the protection scope of the present invention.
As shown in attached drawings 1 and 2, the utility model discloses high low temperature test case transmission shaft connecting hole sealing device comprises connecting plate I1, clamping device I2, heat preservation cotton 3, bellows 4, clamping device II 5, connecting plate II 6.
Connecting plate I1 and connecting plate II 6 pass through fastening bolt respectively and fix on high low temperature case 7 and motor 8, adorn heat preservation cotton 3 on 4 inner walls of bellows, after transmission shaft 9 adorns on motor 8, with the bellows 4 cover that has heat preservation cotton 3 in the transmission shaft 9 outside, with clamping device I2, clamping device II 5 presss from both sides tight bellows 4 and high low temperature case 7 junction and the junction of bellows 4 and motor 8 respectively, form a confined cavity like this, wrap up the transmission shaft at high low temperature test box inboard, motor and other objects have been isolated simultaneously.
The length of the heat insulation cotton 3 is equal to that of the corrugated pipe 4, so that the heat insulation cotton is prevented from being excessively deformed and interfering with a transmission shaft. The corrugated pipe 4 is connected with the end of the motor 8 and then connected with the end of the high-low temperature box 7.
The clamping device I2 and the clamping device II 5 can be universal and are used for clamping after the transmission shaft 9 is connected.
The utility model discloses mainly through install heat preservation device additional between externally driving motor and high low temperature test case, be favorable to the holding of high low temperature test incasement temperature, isolated high low temperature case flows with the outside air, reduces the heat exchange, the device not contact with the transmission shaft simultaneously, eliminates the potential safety hazard, convenient operation, safe and reliable.
