Abstract
The utility model discloses a bearing assembling protection guide device for a traction motor, which comprises a guide barrel and a handle. The guide barrel is made of a nylon material; a fixed panel is vertically and axially arranged inside the guide barrel; a screw hole is arranged on the fixed panel; the front end of the handle is provided with a screw thread section; the screw thread section is in threaded connection with a nut; and the size of the screw thread section is matched with that of the screw hole. The bearing assembling protection guide device for the traction motor has the beneficial effects that the guide barrel made of the nylon material has lower hardness than the bearing, has elasticity and takes an effect of protecting the bearing and the damage to the bearing in the assembling process is reduced; even though the guide barrel is damaged, the bearing assembling protection guide device can also be repeatedly used; and due to the adoption of the guide barrel, the bearing assembling protection guide device is not influenced by the size of a clearance between a roller of a rolling bearing and a retainer, the roller can be uniformly opened toward the peripheral direction by the guide barrel, an installing gap for an inner ring of the bearing is reserved and the bearing assembling protection guide device is convenient for assembly.
Description
Technical field
The utility model relates to a kind of bearing installing tool, particularly a kind of traction electric machine running in bearings protection guiding device.
Background technology
When existing traction electric machine assembles, basically all adopt horizontal fit.To rotor shaft bearing position, it is indoor that bearing outer ring is installed to the end cap bearing with the bearing inner race hot jacket.The end cap of engine commutator end is installed on the stator, stator is lain against on the platform.End cap with non-commutator end installs on the rotor shaft relevant position again, utilizes special hanger that the rotor level is sling.Rotor is inserted in the stator, and pack bearing inner race in the bearing outer ring in the adjustment installation site, rotor is seated.
Existing fit does not generally adopt bearing protection device, and adjusting position is inconvenient, and bearing inner race all has certain axial impact force to bearing roller, retainer, and bearing has certain damage.Cause the different sound of motor bearings, vibration is big, faults such as temperature rise height.
Owing to do not adopt bearing guiding fit, in assembling, during adjusting position, direct current generator causes commutator and the brush-holding device fault of damaging easily.Alternating current generator causes rotor to wipe fault mutually because air gap is less than normal when assembling easily.
The deficiency of above fit is to cause the different sound of traction electric machine bearing in the locomotive operation, and vibration is big, fault one of the main reasons such as temperature rise height, and severe patient can cause bearing dead admittedly, causes the locomotive machine to break fault, even also can cause the locomotive operation safety accident.
The utility model content
The goal of the invention of the utility model is: to the problem of above-mentioned existence, a kind of traction electric machine running in bearings protection guiding device is provided.
The technical scheme that the utility model adopts is such: a kind of traction electric machine running in bearings protection guiding device; Comprise guide barrel and handle; Said guide barrel is processed by nylon material, and its internal vertical axially is provided with fixed panel, and screw is set on the fixed panel; Said handle front end is provided with thread segment, and nut is threaded on the thread segment.The size and the screw of thread segment are complementary.
First kind of optimal way, first kind of structure of said guide barrel is guide barrel one, and its outer surface is a taper surface, and its small end internal vertical axially is provided with fixed panel one, and screw one is set on the fixed panel one.
Second kind of optimal way, second kind of structure of said guide barrel is guide barrel two, and its outer surface is a taper surface, and the center internal vertical axially is provided with fixed panel two, and screw two is set on the fixed panel two.
In above-mentioned two kinds of preferred structures, the outer surface tapering of said guide barrel is 1:10-1:100.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is:
1, the guide barrel processed of nylon material is lower than the hardness of bearing, has elasticity, and bearing is played a protective role, and reduces in the assembling process damage to bearing;
Even 2 guide barrel have damage, also can reuse;
3, adopt guide barrel, do not receive the influence of the gap length of rolling bearing roller and retainer, guide barrel can evenly strut roller to circumferencial direction, reserves the assemblage gap that removes bearing inner race, is convenient to assembling;
4, adopt tapered guide, the bearing axially loaded is little, and is good to neutrality.
