According to the locomotive gearbox, with the adoption of the magnetic fluid sealing ring, a magnetic sealing mode is applied to the shaft end surface sealing of the locomotive gearbox, so that requirements on the coaxiality of the transmission shaft and the neck ring are greatly lowered, a use requirement on the locomotive gearbox in a high-speed running state can be adapted, vibration-resistant capacity and wear-resistant capacity are greatly improved, the sealing effect is stable and reliable, regular maintenance is not required, the maintenance cost of the gearbox and the occurrence of an oil leakage fault are reduced, and the service life of the gear is prolonged.
Description
Technical field
The utility model relates to a kind of drive disk assembly, particularly a kind of rail transit locomotive installing locomotive gear cases.
Background technology
Installing locomotive gear cases is electric locomotive, diesel locomotive, the vitals of the used traction motor output such as light rail and subway driving force function, because the running velocity of locomotive is high, usually be in the use state of running at high speed, installing space is restricted in addition, end such as common gear case is fixed on framework and the drive motor, the other end is suspended on gear shaft terminal, cause gear wheel shaft and gear case sealing eckband to be difficult to the right alignment that keeps higher, this environment for use has proposed very high requirement to the sealing of installing locomotive gear cases, in the prior art, wool felt is adopted in the axial end sealing of installing locomotive gear cases usually, the hermetically-sealed constructions such as labyrinth packing, in use, the felt bar is worn away easily, and oil impregnate occurs for fracture and sealing effectiveness is descended, oil leakage phenomenon; On the other hand, when high-speed operation, also can produce and significantly push away oil effect, the generation that aggravation is leaked even gear wheel shaft resides in the tiny machining screw vestige on axle surface in mechanical processing process.Because the sealing effectiveness missionary society of installing locomotive gear cases causes gear because of the generation of oil starvation abnormal wear even burning tooth fault, therefore, the sealing effectiveness of installing locomotive gear cases is the important factor in order of train operating safety, also can cause the track traffic environmental pollution because of seal leakage simultaneously.
Summary of the invention
The purpose of this utility model: be to provide a kind of installing locomotive gear cases, it can significantly improve the sealing effect, adapts to the environment for use requirement of rail transit locomotive high-speed cruising, has good oil-leakage-prevention performance, long service life, can improve locomotive operation safety, reduce the maintenance and repair cost.
The technical solution of the utility model is:
This installing locomotive gear cases comprises upper box, lower box, and described upper box and lower box connect into the locomotive gear casing of sealing, is provided with the eckband of supporting drive shaft on the described casing, it is characterized in that: be provided with magnetic fluid sealing ring in the described eckband.
Described magnetic fluid sealing ring by the pole shoe that is provided with inner groove radially, be embedded in the annular permanent-magnet body in the pole shoe and form by the absorption of annular permanent-magnet body and to the magnetic liquid that transmission shaft carries out the seize dynamic seal (packing).
Described eckband comprises output shaft eckband, gear wheel shaft eckband, motor cabinet eckband.
Described upper box and lower box are by square flange and Bolt Connection; Described output shaft eckband, gear wheel shaft eckband, motor cabinet eckband all are arranged on the sealing surface of described upper box and lower box.
Described pole shoe outside face has the scrobicular ring that embeds box body wall.
Described pole shoe is combined by two semicircular body, and described annular permanent-magnet body is combined by two semicircular body.
According to above technology propose of the present utility model owing to adopted magnetic fluid sealing ring, the magnetic seal mode is applied in the axial end sealing of installing locomotive gear cases, make the right alignment of transmission shaft and eckband require greatly to reduce, the operating needs of energy adaline parallel operation gear boxes under the high-speed cruising state, the ability of anti-vibration and wearing and tearing increases greatly, sealing effectiveness is reliable and stable, need not to carry out regular maintenance, reduced the generation of gear case maintenance cost and oil leakage fault, can improve the service life of gear case, also can reduce the environmental pollution that causes because of the greasy dirt leakage.

The specific embodiment
Embodiment 1:
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model provides a kind of installing locomotive gear cases, comprise upper box 1, lower box 6, described upper box 1 and lower box 6 connect into the locomotive gear casing of sealing, are provided with the eckband of supporting drive shaft on the described casing, are provided with magnetic fluid sealing ring 2 in the described eckband.
As shown in Figure 1, all be welded with square flange 4 on upper box 1 and lower box 6 face of joints, upper box 1, lower box 6 link into an integrated entity by bolt 3, consist of the locomotive gear box body of sealing, on the sidewall of lower box 6 insert Mirror for indicating oil level 5, at the output shaft eckband 10 of installing locomotive gear cases magnetic fluid sealing ring 2 is housed.Described magnetic fluid sealing ring 2 by the pole shoe 11 that is provided with inner groove radially, be embedded in the annular permanent-magnet body 12 in the pole shoe 11 and form by the absorption of annular permanent-magnet body and to the magnetic liquid 13 that transmission shaft carries out the seize dynamic seal (packing).
Described upper box 1 and lower box 6 connect by square flange 4 and bolt 3, and described output shaft eckband 10, gear wheel shaft eckband 7, motor cabinet eckband 8 all are arranged on the sealing surface of described upper box 1 and lower box 6,
As shown in Figure 2.Particularly, described pole shoe 11 outside faces have the scrobicular ring that embeds box body wall, described pole shoe 11 combines the circle shape by two semicircular ring up and down, similarly, annular permanent-magnet body 12 combines the circle shape by two semicircular body up and down, up and down two semicircular body of described annular permanent-magnet body 12 embed respectively in up and down two semicircular ring of pole shoe 11, and described magnetic liquid 13 is by 12 absorption of annular permanent-magnet body, and gear wheel shaft 9 is carried out side seal.
