Description

Dismounting tool for high-speed shaft oil slinger of wind power gear box Technical Field The utility model relates to the field of maintenance of wind power gearboxes, in particular to a dismounting tool for a high-speed shaft oil slinger of a wind power gearbox. Background Wind power generation has been rapidly developed in recent years due to the advantages of no pollution, low construction cost, and the like. The high-speed shaft system in the wind power gear box is used as an output shaft system in the box body, and the high-speed shaft gear is damaged very frequently in all gear pieces because the rotating speed of the high-speed shaft system is high. If the high-speed shaft detects pitting or slight indentation of the tooth surface, the tooth surface of the high-speed shaft can be subjected to regrinding treatment. Before the high-speed shaft is subjected to gear grinding, small parts such as a bearing, a round nut, an oil slinger and the like which are arranged on the high-speed shaft are all removed. In order to prevent oil leakage, the oil slinger on the high-speed shaft is arranged on the shaft diameter of the high-speed shaft in an interference fit mode, and the oil slinger is difficult to directly dismantle. Usually, the oil slinger in the place is dismantled in a heating mode, and then the high-speed shaft body is influenced by the excessively high temperature due to poor temperature control, so that the quality of the high-speed shaft body is influenced. The technical scheme in the first prior art is as follows: The heating belt is wound on the outer surface of the oil slinger on the high-speed shaft, and after the temperature of the oil slinger is increased, the oil slinger is detached from the high-speed shaft by beating the flange part of the oil slinger. The first disadvantage of the prior art is: 1. The heating time of electric heating belt is not well controlled, if heating time is too short, the degree of oil slinger thermal expansion is not enough, still can't follow high-speed epaxial dismantlement with the oil slinger through the mode of beating the oil slinger flange, still needs to continue the heating, waste time. If the heating time is too long, after heat is conducted onto the high-speed shaft body, the shaft diameter of the high-speed shaft is expanded after being heated, so that the heating time is too long and the high-speed shaft is not easy to disassemble. 2. The oil slinger flange is knocked in a knocking mode, if the oil slinger flange is knocked to the upper surface of the high-speed shaft body in the knocking process, a flaw is easily left on the high-speed shaft, and a certain danger exists for workers in the knocking process. The technical scheme of the second prior art is as follows: and (3) aligning the flame with the outer circle of the oil slinger by using a flame gun, and detaching the oil slinger in a continuous heating mode. The second prior art has the following defects: 1. the flame temperature sprayed by the flame spraying baking gun is higher, the high-speed shaft needs to be hung, and the high-speed shaft needs to be continuously rotated so as to avoid local overhigh temperature, and two people are required to operate at the same time. And once the flame gun is operated improperly, workers are injured. Disclosure of utility model The utility model provides a dismounting tool for a high-speed shaft oil slinger of a wind power gear box, which aims to solve the defects in the prior art, and is operable by a single person, high in universality, safe and reliable and free from damaging the high-speed shaft. The technical scheme adopted for solving the technical problems is as follows: Dismantlement frock of wind-powered electricity generation gear box high-speed shaft oil slinger interference fit installs on the diameter of axle of high-speed shaft, its characterized in that: clamping the tooling flat plate to clamp the oil slinger, and propping the upper surface of the tooling flat plate against the lower surface of the flange of the oil slinger; The middle part that is located the dull and stereotyped of drive frock of terminal surface top of high-speed axle has the screw hole, drive frock bolt spiral shell is established in this screw hole and is passed the dull and stereotyped of drive frock, the screw rod bottom of drive frock bolt and the terminal surface contact of high-speed axle, the dull and stereotyped through-hole that has respectively of drive frock in the both sides of this screw hole, two studs pass the through-hole of this screw hole both sides respectively, the lower extreme spiral shell of stud establishes the dull and stereotyped corresponding screw hole of centre gripping frock inside, the upper end spiral shell of stud is equipped with round nut, round nut tightly supports the dull and stereotyped upper surface of drive frock, thereby the dull and stereotyped fixed connection of drive frock and centre gripping frock. The clamping tool flat
