Description

Cooling end cover of gear box

Technical Field

The utility model relates to a gear box especially relates to a cooling end cover of gear box.

Background

At present, a cooling system is not added in a synchronous gearbox of most fuel cell air compressor systems in the market or lubricating grease is externally pumped out and cooled; the gear in the gear box without the cooling system can generate concentration increase due to the influence of high temperature, so that the gear generates extra resistance under the condition of high-speed rotation, the grease can deteriorate under the state of high temperature for a long time, the lubricating effect can not be achieved, the gear is abraded, the transmission system can be lowered after a long time, and the problem of non-reversibility is caused.

The cost of the cooling system is increased by pumping the lubricating grease out for external cooling, the external cooling system causes the problem of overlarge assembly space of the whole air compressor system, and the external cooling system also needs to be maintained and replaced regularly, so that the after-sale cost is increased.

SUMMERY OF THE UTILITY MODEL

To the problem that the inside temperature that leads to because of the gear operation risees among the above-mentioned prior art in the gear box, the utility model provides a gear box cooling end cover.

In order to achieve the above object, the present invention provides the following technical solutions:

a gear box cooling end cover is provided with two end faces, wherein one end face is a pump head connecting face, and the other end face is a motor connecting face; a cooling water channel is arranged on the pump head connecting surface; and the water inlet of the cooling water channel is arranged on the motor connecting surface and is communicated with the cooling water channel of the motor.

Preferably, the water outlet of the cooling water channel is arranged on the side wall of the ring connecting the two end faces.

Preferably, in the above technical solution, the opening position of the water outlet is lower than the opening position of the water inlet.

Preferably, an oil filling port is formed in the position, corresponding to the water outlet, of the side wall of the ring, and the oil filling port is communicated with an oil chamber in the gear box.

Preferably, the end cover is further provided with a bearing chamber, and two end faces are communicated through the bearing chamber; the bearing chamber is used for connecting the pump head and the motor shaft head.

Preferably, in the above technical solution, the cooling water channel is an unclosed annular channel and is disposed around the bearing chamber.

The utility model discloses the beneficial effect who has does:

the cooling water channel is arranged in the end cover, and a cooling medium circulates in the cooling water channel, so that high-temperature grease caused by rotation of the gear in the gear box can be cooled, and a large amount of heat generated by a shaft head at the end of the motor can be taken away; meanwhile, a cooling system of the gear box and a motor cooling system are integrated into a system, so that the complexity of the whole cooling system of the air compressor is greatly reduced, the selling price of the product and the after-sale maintenance cost are also reduced, and the durability of the product is improved.
