Abstract
Disclosed is a mechanism of a copper bar rotor motor for preventing rupture of a copper bar, which is characterized in that: rigid supporting members are arranged between a rotor end ring and a rotor pressing ring, notches are evenly disposed along the circumference near the inner circle of the end ring at the outer side of the rotor end ring, one end of each rigid supporting member is inserted into the corresponding notch of the rotor end ring, and the other end thereof is fixed on the rotor pressing ring; and the notches are corresponding to the rigid supporting members in quantity. The rigid supporting members are arranged between the rotor end ring and the rotor pressing ring, so the inertia torsional moment of the motor end ring can act on the rigid supporting members, the copper bar need not bear the inertia torsional moment, the problem of easy rupture of the jointed root part of the motor rotor copper bar and the rotor end ring is effectively solved, and the service life of the motor is effectively extended.
Description
Technical field
The utility model relates to the mechanism that a kind of copper bar rotor motor prevents the copper bar fracture.
Background technology
At present, because frequency converter is increasingly extensive in the operating application of motor, in order to satisfy the needs of operating mode, often needing to adjust motor speed, as the drive motors of hoist engine, crane etc., is exactly like this.In the copper bar rotor motor, end ring is fixed on the rotor bar (being copper bar), because motor speed frequently changes, end ring has the torsional moment effect of an inertia to copper bar under the work of the moment of inertia.Because the copper bar softness, rigidity is not enough, and under the inertia torsional moment effect of electric machine end ring, the root that copper bar is connected with end ring ruptures easily, causes motor to damage, and influences motor and uses.
The utility model content
The purpose of this utility model is to provide a kind of copper bar rotor motor to prevent the mechanism of copper bar fracture, to prolong the useful life of motor.
The technical solution of the utility model is: between rotor end ring and rotor pressing ring, rigid support is set, the rotor end ring outside evenly has notch by circle in the end ring along circumference, and an end of rigid support embeds in the notch of rotor end ring, and the other end is fixed on the rotor pressing ring; Notch quantity is corresponding with rigid support quantity.
Described rigid support is preferably " Z " font.
The quantity of described rotor end ring notch can determine that the rotor end ring size is big more according to the rotor end ring size, and rotor end ring notch quantity should be more, the also corresponding increase of the quantity of rigid support.The quantity of rotor end ring notch and the quantity of rigid support are generally 4-12.
The utility model is by being provided with rigid support between rotor end ring and rotor pressing ring, the inertia torsional moment of electric machine end ring is acted on the rigid strutting piece, copper bar needn't bear the effect of inertia torsional moment, efficiently solve the easy problem that ruptures of root that the rotor copper bar is connected with rotor end ring, effectively prolong the useful life of motor.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the front view of rotor end ring embodiment illustrated in fig. 1.
Fig. 3 shows the left view of embodiment rotor end ring for Fig. 1.
Among the figure: 1. rotor copper bar; 2. rotor end ring; 3. rigid support; 4. rotor pressing ring; 5. rotor end ring notch.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing, present embodiment is provided with " Z " font rigid support 3 between rotor end ring 2 and rotor pressing ring 4, rotor end ring 2 outsides evenly have notch 5 by circle in the end ring along circumference, one end of rigid support 3 embeds in the notch 5 of rotor end ring, and the other end is fixed on the rotor pressing ring 4.
Have four notches on the present embodiment rotor end ring 2, correspondingly, be provided with 4 of " Z " font rigid strutting pieces.
