Abstract
The utility model discloses an overhauling tool for an electric motor, which is used for the disassembly of electric motors. The utility model is characterized in that a jack of which the end is lathed with external screw threads is engaged with a triangle nut of which the top end is lathed with internal screw threads. Push rods with different lengths can be arranged on the top end of a movable shaft of the jack to meet the different requirements of the electric motors with shafts with different lengths. The utility model has the advantages of simple structure, convenient operation, labour saving, time saving and high efficiency.
Description
The utility model relates to a kind of instrument that motor is used that overhauls.
Motor in use usually needs periodic inspection or changes bearing, the dismounting motor is the work of comparatively requiring great effort for the electrical machmary maintenance personnel, special when bearing with spool cooperate comparatively closely, and the gap of the little FE Tiler of bearing back and bearing is when very little, it is very difficult that bearing removal is got off.It is a kind of dismounting motor instrument that the electrical machmary maintenance worker uses always that present triangle draws horse, and it is to catch bearing by a triangle machinery handgrip, and again with leading screw top motor shaft, also having a kind of way is to cooperate take off daughter board, lead screw, jack etc. with use.Since triangle draw horse be by rotating threaded shaft force transmission to the motor shaft a bit, in use effort is especially just more required great effort when leading screw and electrical axis have deviation slightly very, and fragile motor shaft.It is cumbersome that daughter board is taken off in use, usually needs length conversion screw mandrel or increase jack liner according to motor shaft, because each parts disperses, is difficult for taking care of, and uses also inconvenient.
The purpose of this utility model provides dismounting motor instrument a kind of simple in structure, easy to use, time saving and energy saving.
Task of the present utility model is finished by following approach: have the jack of external thread wire and the triangle of top car internal thread silk to draw horse to mesh together in the top car, by adorning a motor shaft push rod, it is different and decide that the length of push rod can be pressed motor shaft length on the top of jack movable axis.
The utility model has the advantages that simple structure is easy to use, save time, laborsaving, the efficient height, overhauling a 160KW motor originally needs three people to do one day, uses the utility model only to need two people to do half a day.Because the length of push rod can be adjusted, thus be not only applicable to dismantle the motor bearings of different size, and be applicable to the dismounting different size to wheel, end cap, fan etc., also be applicable to other work posts such as pincers worker simultaneously.
Accompanying drawing 1 is the installation diagram that the utility model intermediate cam is drawn horse.
Accompanying drawing 2 is installation diagrams of jack and push rod in the utility model.
Accompanying drawing 3 is work schematic diagrames of the present utility model.
End external threading silk with jack (3), triangle is connected as a single entity its engagement after drawing the top car internal thread silk of horse (1), select the push rod (2) of appropriate length to be inserted in the endoporus on jack (3) movable axis top according to the length of motor shaft during use, draw the handgrip of horse (1) to catch motor bearings with triangle, the other end of push rod withstands motor shaft, the work that just can dismantle motor bearings after the jack action.
Claims (1)
1, a kind of machinery check and repair instrument that draws horse to form by triangle is characterized in that it is to have the triangle of the jack of external thread wire and top car internal thread silk to draw horse to mesh together by the top car to constitute, and the motor shaft push rod is installed in the top of jack movable axis.
