Description
Technical Field
The utility model belongs to the technical field of wind power equipment, specifically speaking relates to a special frock for installing bearing inner and outer lane.
Background
The inner ring and the outer ring of the bearing are important parts of the fan unit, are used for determining the relative movement position of the rotating shaft and other parts, and play a role in supporting or guiding. Its main function is to support the main shaft of the fan to reduce the mechanical load friction coefficient of the equipment in the transmission process. As the size and the weight of the bearing outer ring are overlarge and are precise parts, the bearing outer ring needs to be frozen before assembly, the method adopted in the prior art is to put the bearing outer ring in dry ice for freezing, and the heat is preserved for not less than 1 hour. After freezing, the bearing outer ring is lifted by using a lifting appliance and is positioned and installed by an operator wearing the low-temperature-prevention gloves, the assembly standard cannot be reached without paying attention, the angle can not be adjusted, the bearing outer ring can be lifted repeatedly, after the temperature of the outer ring rises, the bearing outer ring needs to be continuously placed into dry ice for freezing, and the actions are repeated. Therefore, the installation is difficult and inefficient, and the actual operator can repeat the installation for 2 to 3 times.
The bearing inner ring needs to be heated before being assembled, and the method adopted in the prior art is to put the bearing inner ring on a heater to heat to 120 ℃ and keep the temperature for not less than 1 hour. After heating, the bearing inner ring is lifted by the lifting appliance and is positioned and installed by an operator wearing high-temperature protective gloves in a hand way, the steps are completed within 5 minutes, the assembly standard cannot be reached without paying attention to the steps, the angle cannot be adjusted, the bearing inner ring can be lifted again and heated for repeated lifting, and the installation is difficult and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a special frock for installing bearing inner and outer lane has solved the shortcoming of difficult, the inefficiency of bearing inner and outer lane installation among the background art.
The technical scheme of the utility model is realized like this: a special tool for mounting inner and outer rings of a bearing comprises a lifting lug, wherein a cross beam is arranged below the lifting lug, two vertical beams are arranged below the cross beam, a support rib I and a support rib II are respectively arranged between two ends of the cross beam and the vertical beams, a worm gear speed reducer is arranged at the lower end of one side of each vertical beam, one end of the worm gear speed reducer is connected with a hand wheel, the other end of the worm gear speed reducer is connected with a rotating shaft, one end of the rotating shaft is connected with the bearing, the other end of the rotating shaft is connected with a connecting beam II, one end of the connecting beam II and one end of the connecting beam I;
preferably, the mounting plate and the bearing outer ring are fixedly connected together through a pressure plate and a bolt;
preferably, the mounting plate and the bearing inner ring are fixedly connected together through bolts.
The utility model has the advantages that: the utility model discloses can install fast bearing inner and outer lane, have the installation rapidly, at will angle of adjustment, advantage that the installation accuracy is high, thereby once just the mountable makes efficiency improve greatly successfully.
