Description
Technical field
The present invention relates to the transmission device technical fields of rail traffic, and in particular to a kind of planet gear transmission device.
Background technology
Involute planet gear transmission device have in retarder it is commonly used, especially in industries such as automobile, wind-powered electricity generations.It has
There are small, light-weight, large carrying capacity, efficient, stable working.Compared with common cylinder gear drive, transmission ratio is big, body
Product and weight can reduce by 50% or so, efficiency and improve 3%.Involute planet gear lubrication is generally splash oil lubrication, needs
The one gear housing cogged lubricating oil with good seal performance.If poor sealing or oil are deteriorated, oil can be caused
Amount is reduced, and lubrication is unreliable, and transmission device inner bearing can be caused to overheat dead, the risk of transmission failure when serious.
Since planetary gear transmission mechanism is compact, while outer end cap is that revolving part is non-static, traditional inspection glass for oil level dress
It sets and is typically directed to what static gearbox case designed, it is difficult to adapt to the planet gear transmission device that outer end cap is revolving part.
Automobile industry uses the design of oil level indicator and sensor at present, judges oil mass and liquid in babinet by scale viscous oil height respectively
Oil mass in the sensor perception case of face.Oil level indicator cannot be observed in real time, poor in timeliness；And sensor needs wiring and electrical equipment,
Increase the unreliability of operation.Current track transportation industry is using the oil level glass observation mounted on gear-box bottom
Oil level, this needs gear-box is opposite to stand, and position is fixed, and after gear case oil is fallen after rise when static, oil level is observed by windowpane.Rail
Road industry handling capacity of passengers is big, it is desirable that reliability it is more much higher than automobile, traditional oil level indicator use Blind Test method, it has not been convenient to it is daily
Observation and maintenance are badly in need of a kind of intuitive, reliable device of design and meet the observation of planet gear transmission device oil mass.The invention can be very
Good solves the problems, such as this, and the maintenance for providing the rail vehicle using Planetary Gear Transmission more convenient safety ensures.
