Abstract
The utility model discloses a semi-hollow motor rotor sling in order to solve the problem that a semi-hollow rotor shaft cannot be lifted. The semi-hollow motor rotor sling comprises circlips for shaft, protective copper sleeves, lifting plates and lifting rings, wherein the circlips for shaft are clamped in retainer ring grooves; the lifting plates are provided with seam allowances; the protective copper sleeves are inlaid into the seam allowances of the lifting plates; two lifting holes are formed in the lifting plates; and the lifting rings are arranged in the lifting holes. The semi-hollow motor rotor sling is simple in structure and convenient to replace, is safely and conveniently operated, has high universality and can be suitable for shaft rotors of different sizes according to different shaft sizes.
Description
Technical field
The utility model relates to field of motor manufacturing, specifically a kind of semi-hollow motor rotor suspender.
Background technology
AC motor rotor cage bar and end ring (end ring is blind hole) welded structure adopts medium frequency inductive brazing.Motor rotor must be put on the intermediate-frequency welding machine before the welding, according to the form of different motor reels, need make corresponding frock, most solid axle wherein, there is centre hole at the two ends of axle, can establish hole for hoist, and the installation suspension ring directly are put into axle on the intermediate-frequency welding machine.With the in midair axle of spline, just be difficult to establish hole for hoist for an end, it is fixing that spindle nose and axle are squeezed into straight pin after by hot charging, the structure of axle as shown in Figure 1, spindle nose 11 is flush fit with axle body 12, further fixing by bearing pin 13, this structure can't be used suspension ring.
The utility model content
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of semi-hollow motor rotor suspender, can solve the lifting problem of in midair axle as shown in Figure 1, and concrete scheme is as follows:
A kind of semi-hollow motor rotor suspender, it is characterized in that: comprise circlip for shaft 2, protection copper sheathing 3, lifting plate 4, suspension ring 1, described circlip for shaft 2 is stuck in the back-up ring groove, described lifting plate 4 arranges seam, described protection copper sheathing 3 is bumped in the seam of described lifting plate 4, be provided with two holes for hoist at the lifting plate, described hole for hoist is installed suspension ring 1;
Protection copper sheathing 3 internal diameters are interference fit than the large 0.2mm-0.3mm of the diameter of axle between protection copper sheathing 3 external diameters and the lifting plate 4 seam internal diameters;
Described seam gear platform diameter is than the large 0.2mm-0.3mm of shaft diameter, and the circlip for shaft external diameter is generally than the large 3mm-4mm of the diameter of axle.
The utility model has the advantages that: simple in structure, easy-to-operate; Have commonality, different according to shaft size, applicable to the axle rotor of different size, be convenient to change.
Description of drawings
Fig. 1 is for needing the rotor structure scheme drawing of lifting;
Fig. 2 is the utility model structural representation;
Fig. 3 is the birds-eye view of Fig. 2.
The specific embodiment
Specify the utility model below in conjunction with accompanying drawing; such as Fig. 2, shown in Figure 3; the utility model comprises circlip for shaft 2, protection copper sheathing 3, lifting plate 4, suspension ring 1; described circlip for shaft 2 is stuck in the back-up ring groove; described protection copper sheathing 3 is bumped in the described lifting plate 4; be provided with two holes for hoist at the lifting plate, described hole for hoist is installed suspension ring 1.
During lifting suspender elder generation direct-axis left end is inserted in the bearing stand place; the circlip back-up ring groove of packing into; again with the suspension ring rotor of slinging; the constructional feature of suspender is: the left end at axle is the bearing table top; in order to prevent that hoisting process from bumping to the bearing table top; the centre hole of this suspender is bumped into a copper sheathing; protection copper sheathing 3 internal diameters are than the large 0.2mm-0.3mm of the diameter of axle; be interference fit between protection copper sheathing 3 external diameters and the lifting plate seam internal diameter; be unlikely in use to come off; in order to make suspender in use not have the upper and lower tropism, we are lifting plate bore design the seam formula simultaneously, and gear platform footpath 301 is than the diameter of axle 5 large 0.2mm-0.3mm.The circlip for shaft external diameter is generally than about the large 3mm-4mm of the diameter of axle, and the suffered rotor pressure of copper sheathing passed on the lifting plate when suspender lifted in the front like this, and the weight of rotor directly acts on the lifting plate during reverse side lifting.It all is safe that positive lifting or reverse side lift.By suspension ring 1 rotor is sling, be put on the intermediate-frequency welding machine welded disc turbine rotor cage bar and end ring.
Claims (3)
1. semi-hollow motor rotor suspender; it is characterized in that: comprise circlip for shaft, protection copper sheathing, lifting plate, suspension ring; described circlip for shaft is stuck in the back-up ring groove; described lifting plate arranges seam; described protection copper sheathing is bumped in the seam of described lifting plate; be provided with two holes for hoist at the lifting plate, described hole for hoist is installed suspension ring.
2. rotor lifter according to claim 1 is characterized in that: described protection copper sheathing internal diameter is than the large 0.2mm-0.3mm of the diameter of axle, and protection copper sheathing external diameter is interference fit with lifting between the plate seam internal diameter.
3. rotor lifter according to claim 1 is characterized in that: described seam gear platform diameter is than the large 0.2mm-0.3mm of shaft diameter, and the circlip for shaft external diameter is generally than the large 3mm-4mm of the diameter of axle.
