Abstract
The utility model relates to a cage-shaped rotor anti-break device for a large and medium-sized asynchronous motor, which is composed of a guide strip, an end ring and a connecting member. The utility model is characterized in that an axial connection hole is arranged on a slot-shaped connection surface which is vertical to an axial cord and is arranged on the connection end surface of the guide strip and the end ring, and the connecting member is arranged in the axial connection hole and is axially connected with the guide strip and the end ring so as to form the cage-shaped rotor anti-break device for a large and medium-sized asynchronous motor. The connecting member of the device is the same as a key and makes the guide strip and the end ring fixedly connected together, so the guide strip can not be separated from the end ring to damage a stator by centrifugal force. The utility model reduces the accident rate of a motor, and prolongs service life.
Description
The utility model is to belong to cage type asynchronous motor rotor breaker strip equipment.
At present, for big-and-middle-sized asynchronous cage type motor,, account for the 15-20% of the total accident of this motor because of the accident that rotor broken bar causes.In order to prevent because of after the solder fusing, because of action of centrifugal force throws away sliver from the end ring groove, draw and decrease stator, on the external diameter of sliver and end ring, put a retaining ring, because motor specification is many, size is big, requires the retaining ring specification, and size is big, physical property for the materials of its ring is had relatively high expectations, so its processing technology complexity, cost is higher, influences it and applies.
The purpose of this utility model proposes a kind of large and medium asynchronous motor cage-type rotor anti-break device, and its device is between the solder joint of sliver and end ring, adds a connector, prevent because of after the solder fusing, sliver throws away and damages stator, and its technology is simple, and is effective.
The utility model is made up of sliver 1, connector 2, end ring 3, shown in Fig. 1,2,3,4; It is characterized in that: connecting on the end face with end ring 3 at sliver 1 has axial connection holes on the grooved conjunction plane perpendicular to axis, and connector 2 places in the axial connection holes, and is fixedly connected with sliver 1, end ring 3 respectively.
The sliver of the cage-type rotor of large and medium asynchronous motor is to penetrate rotor core, and respectively overhangs one section at the iron core two ends, and the sliver of its overhanging section is distinguished in the insertion end annular groove, and with method for welding sliver is connected with end ring.Because on-stream all multifactor of motor, make rotor, sliver is overheated and make weld seam solder fusing between the two, sliver is easy to be thrown out of the damage stator under the centrifugal action of high speed rotating, the utility model be on a radial side that connects end face grooved conjunction plane of sliver and end ring, add porose, this hole strides and is associated in conjunction plane, sliver, above the end ring, and connector places in this hole, as same key, add the scolder soldering in the seam of its contact surface, sliver and end ring firmly are linked together.Because this connector is to connect on the radial side of end face with end ring at sliver, even solder fusing, under centrifugal action, sliver can not break away from end ring yet and get rid of.
The utility model compared with prior art, because connector is to straddle on the radially solder joint of sliver and end ring conjunction plane, and in axial direction connects with sliver, end ring, as same key, sliver and end ring are fixed together, can not damage stator because of rotor centrifugal force breaks away from end ring with sliver, it is simple in structure, handling ease, cost is low, can save human and material resources, reduce the rate of failure of motor, prolong its useful life.

Embodiment of the present utility model:
The utility model is made up of sliver 1, connector 2, end ring 3.Large and medium asynchronous motor cage-type rotor anti-break device, as shown in the figure; Wherein sliver 1, end ring 3 are to select part for use, and are drilled with the hole on a radial side of sliver 1 and the grooved conjunction plane of end ring 3, and the hole is striden on connection sliver 1, end ring 3 end faces, as shown in the figure; Connector 2 is processed into pin, screw form by the size in hole.
