Utility model content
The utility model provides a kind of push-bench gear-box waterproof construction, adopts the following technical scheme that:
A kind of push-bench gear-box waterproof construction, comprising: cabinet and transmission shaft;Transmission shaft is relative to body pivot;Push pipe Machine gear-box waterproof construction further include: for the intracorporal gas of case to be discharged with the inside and outside air pressure of balance box and prevents cabinet External water enters the uniaxial pressure abat-vent of box house and for being sealed against the resistance to of only lubricating grease leakage to cabinet Press outside framework oil seal;Uniaxial pressure abat-vent is installed to cabinet;Two pressure-resistant outside framework oil seals are in contact and cover forward or backwards respectively It is located on transmission shaft;Uniaxial pressure abat-vent, which has, to be discharged for the intracorporal gas of case to reduce the exhaust condition of pressure and resistance The only closed state that the intracorporal gas of case discharges;When the intracorporal air pressure of case is greater than cracking pressure value, uniaxial pressure ventilation Cap enters exhaust condition from closed state;Cracking pressure value is more than or equal to 0.015Mpa and is less than or equal to 0.025Mpa;Pressure-resistant bone Cracking pressure value of the pressure value that frame oil sealing is able to bear more than or equal to 80 times and the cracking pressure value less than or equal to 200 times.
Further, cracking pressure value is more than or equal to 0.02Mpa and is less than or equal to 0.025Mpa.
Further, cracking pressure value is equal to 0.02Mpa.
Further, the pressure value that pressure-resistant outside framework oil seal is able to bear is more than or equal to 100 times of cracking pressure value and is less than Cracking pressure value equal to 120 times.
Further, lubricating grease is marked between two pressure-resistant outside framework oil seals.
Further, pivot center of the direction of uniaxial pressure abat-vent directional later exhaust movement perpendicular to transmission shaft.
What the utility model was beneficial in that the push-bench gear-box waterproof construction of offer can effectively prevent cabinet Interior lubricating grease leakage.Box house gas can be discharged in uniaxial pressure abat-vent, reduce internal pressure, to reduce pressure-resistant bone Frame oil sealing by pressure.With preferable sealing effect.Pass through the pressure value of specific cracking pressure value and pressure-resistant outside framework oil seal Setting so that service life with higher.

Push-bench gear-box waterproof construction 10, cabinet 11, transmission shaft 12, uniaxial pressure abat-vent 13, pressure-resistant outside framework oil seal 14。
Specific embodiment
Specific introduce is made to the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 to Figure 3, a kind of push-bench gear-box waterproof construction 10, comprising: cabinet 11 and transmission shaft 12.Transmission Axis 12 is rotated relative to cabinet 11.Push-bench gear-box waterproof construction 10 further include: uniaxial pressure abat-vent 13 and pressure-resistant skeleton Oil sealing 14.
Uniaxial pressure abat-vent 13 is used for the gas discharge cabinet 11 in cabinet 11 is outer with 11 inside of balance box and outer Portion's air pressure, and the water outside cabinet 11 can be prevented to enter inside cabinet 11.Specifically, uniaxial pressure abat-vent 13 is installed to case Body 11.
Pressure-resistant outside framework oil seal 14 is for being sealed against only lubricating grease leakage to cabinet 11.Based on above scheme, push pipe Machine gear-box waterproof construction 10 includes four pressure-resistant outside framework oil seals 14.Two in four pressure-resistant outside framework oil seals 14 are set in transmission One end of axis 12 simultaneously contacts with each other.And other two in four pressure-resistant outside framework oil seals 14 is set in the other end of transmission shaft 12, Equally contact with each other.Two pressure-resistant outside framework oil seals 14 to contact with each other are set on transmission shaft 12 forward or backwards respectively.
It is discharged for the gas in cabinet 11 specifically, uniaxial pressure abat-vent 13 has to reduce the exhaust of pressure State and the closed state for preventing the gas in cabinet 11 from discharging.When the air pressure in cabinet 11 is greater than cracking pressure value, Uniaxial pressure abat-vent 13 enters exhaust condition from closed state, to realize exhaust to reduce pressure.
As a preferred embodiment, cracking pressure value is more than or equal to 0.015Mpa and is less than or equal to 0.025Mpa. Cracking pressure value of the pressure value that pressure-resistant outside framework oil seal 14 is able to bear more than or equal to 80 times and the unlatching pressure less than or equal to 200 times Force value.
Specifically, it is unidirectional to be less than 0.015Mpa for pressure in gear-box in the setting range of above-mentioned pressure value Pressure-vent cap 13 is in closed state to carry out waterproof.When pressure is less than 0.015Mpa uniaxial pressure abat-vent 13 in gear-box Into exhaust condition to be exhausted.
As a preferred embodiment, cracking pressure value is more than or equal to 0.02Mpa and is less than or equal to 0.025Mpa.
As a preferred embodiment, cracking pressure value is equal to 0.02Mpa.
As a preferred embodiment, the pressure value that pressure-resistant outside framework oil seal 14 is able to bear is more than or equal to 100 times Cracking pressure value and it is less than or equal to 120 times of cracking pressure value.
Specifically, the specific setting of pressure value and cracking pressure value that pressure-resistant outside framework oil seal 14 is able to bear so that compared with Sealing effect with higher in the case where small cost.Service life is high.
As a preferred embodiment, being marked with lubricating grease between two pressure-resistant outside framework oil seals 14.
