[0006] However, the temperature of the heater 4 with increased power rises rapidly after power-on, so that the temperature of the lubricating oil 3 around it also rises rapidly. Because the thermal conductivity of the gearbox lubricating oil 3 is very low, the heat produced by the heater 4 cannot be quickly The heat conducts out, causing the lubricating oil 3 around the heater 4 to easily deteriorate in quality at high temperature, especially after the lubricating oil 3 is heated many times, the speed of the lubricating oil 3 deteriorating will be accelerated
For example, it is easy to oxidize and deteriorate, the color of lubricating oil turns black, and deposits are produced, which accelerates the wear of parts.
In order to ensure that the parts are not severely worn, the staff have to shorten the use time of the lubricating oil 3 and increase the number of replacements of the lubricating oil 3, resulting in an increase in the operating cost of the gearbox

The invention discloses a gear box which comprises a seal cavity (2) defined by a box body (1), and lubricating oil (3) arranged in the seal cavity (2), wherein the bottom of the seal cavity (2) is also provided with a heater (4) used for heating the lubricating oil (3); and the seal cavity (2) is also internally provided with a lubricating oil circulating device (5) which is used for pumping out the lubricating oil (3) which is close to the heater (4) and transmitting the pumped lubricating oil to a place which is far away from the heater (4). After the lubricating oil circulating device is adopted, the lubricating oil arranged in the seal cavity is ensured to be evenly heated, so that the phenomenon that the quality of the lubricating oil around the heater gets poor when the temperature of the lubricating oil is overhigh can be avoided, the service life of the lubricating oil is greatly prolonged, and the operating cost of the gear box is lowered. The invention also provides a wind power generator which comprises a speed-up gear box which adopts the gear box disclosed by the invention, so that the same technical effect can be achieved.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a gear box. In addition, the present invention also relates to a wind power generator comprising the above-mentioned gear box. Background technique [0002] The gear box of the speed increaser is an important part of the wind power generation unit. With the increase of the installed capacity of a single unit, the heat generated by the meshing between the gear pairs in the gearbox and the friction between the bearings also increases. Therefore, the amount of lubricating oil in the speed-up gearbox also increases. In addition to lubricating, these lubricating oils are also used for heat dissipation of each friction pair and meshing pair, so as to prevent the friction pair of the bearing from occluding due to high temperature, or the tooth surface of the meshing pair of the gear from gluing due to high temperature, which will cause the entire gear Box fails.
