Abstract
The utility model provides a motor rotor copper bar end connection structure, install the rotor punching on the rotor shaft, a plurality of copper bars of installation in the slotted hole on the rotor punching, the both ends of every copper bar respectively with set up in the copper end links axial one end welding towards piece both sides together, the copper end links is installed on balanced clamping ring, balanced clamping ring is installed on the rotor shaft, balanced clamping ring passes through the shop bolt with the copper end links to be fixed together, integrative outer convex ring has on the balanced clamping ring, the interior installation end hoop of ring channel that forms between outer convex ring and the above -mentioned copper end links, the axial ring of end hoop meets with the ring channel, annular slotted hole is established towards the axial tip of copper bar to the copper end links, the tip of copper bar stretches into in this slotted hole, and the copper bar is sawtooth surface with the terminal surface processing of being connected of copper end links. Compared with the prior art, the utility model it is reliable and stable to have copper bar end connection, guarantees motor performance and life, improves advantages such as motor work efficiency.
Description
Technical field the utility model relates to a kind of motor component syndeton, particularly relates to a kind of syndeton of motor rotor copper bar.
Background technology rotor is motor core rotating parts, and existing motor cast-aluminum rotor may occur the defect such as slag inclusion and pore when cast aluminium, especially strengthens at overload magnification, occasion that starting current is high, also there will be the phenomenon that localized hyperthermia's aluminium melts and occurs; The electric conductivity of copper rotor is better than cast-aluminum rotor, the basic structure of existing copper rotor is: armature spindle installs rotor punching, install some copper bars in slotted eye on rotor punching, the two ends of every copper bar weld together with the axial one end of the copper end ring being arranged on punching both sides respectively; Copper end ring is arranged on balance trim ring, balance trim ring is arranged on armature spindle, and balance trim ring and copper end ring is fixed together by shop bolt, balance trim ring has the outer bulge loop of one, installation end hoop in the cannelure formed between outer bulge loop and above-mentioned copper end ring, the axial rings of end hoop connects with cannelure.The end connection request of existing copper rotor to copper bar is higher, plane-welding is taked between current copper bar and copper end ring, and end hoop relies on balance trim ring and copper end ring to clamp, this copper bar welding edges mode operationally, because copper bar welding region is not firm, copper bar can offset by the effect of centrifugal force, brings very large impact to the performance and used life of motor.
It is reliable that summary of the invention the purpose of this utility model is to provide a kind of copper bar end stable connection, ensures motor performance and useful life, improve the motor rotor copper bar end connecting of motor working efficiency.
The improvement of the utility model mainly copper bar end connection portion of existing motor copper rotor, concrete technical scheme is as follows:
The utility model mainly includes armature spindle, rotor punching, copper bar, copper end ring, end hoop, balance trim ring and shop bolt, wherein armature spindle installs rotor punching, install some copper bars in slotted eye on rotor punching, the two ends of every copper bar weld together with the axial one end of the copper end ring being arranged on punching both sides respectively; Described copper end ring is arranged on balance trim ring, balance trim ring is arranged on armature spindle, and balance trim ring and copper end ring is fixed together by shop bolt, described balance trim ring has the outer bulge loop of one, installation end hoop in the cannelure formed between this outer bulge loop and above-mentioned copper end ring, the axial rings of end hoop connects with cannelure; Described copper end ring establishes annular slotted eye towards the axial end portion of copper bar, and the end of copper bar is stretched in this slotted eye, and the connecting end surface of copper bar and copper end ring is processed as serrated face, to increase bonding area.
Preferably, described balance trim ring has the ring that turns up be connected as a single entity with it on the axial end of punching, and this ring that turns up withstands on the axial end of punching.
Preferably, the axial rings of described end hoop connects with cannelure interference.
Utility model works form is same as the prior art, and copper bar both ends are serrated face, and stretches in copper end ring annular slotted hole, the contact area of welding fluid can be strengthened like this, increase welding region, interference fit taked by end hoop, and copper bar can be avoided to offset by centrifugal action.
The utility model compared with prior art tool has the following advantages:
1, the welding of copper bar both ends is more firm, firm, the occasion comparatively large at motor overload multiple, starting current is high, can not impact, improve motor working efficiency, extend the useful life of motor simultaneously because copper bar welding edges loosely runs complete machine.
2, technique, simple structure, without other appurtenances, realize welding with shape and annexation firm, cost of manufacture is cheap, Be very effective.
Description of drawings 1 is partial cutaway schematic of the present utility model.
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Next embodiment just elaborates to the utility model by reference to the accompanying drawings
As depicted in figs. 1 and 2, armature spindle 1 is installed rotor punching 2, install some copper bars 3 in the slotted eye on rotor punching, the two ends of every copper bar weld together with the axial one end of copper end ring 4 being arranged on punching both sides respectively; Described copper end ring is arranged on balance trim ring 5, balance trim ring is arranged on armature spindle, and balance trim ring and copper end ring is fixed together by shop bolt 6, described balance trim ring has the outer bulge loop 5-1 of one, installation end hoop 7 in the cannelure formed between this outer bulge loop and above-mentioned copper end ring, the axial rings 7-1 of end hoop connects with cannelure interference; Described copper end ring establishes annular slotted eye 8 towards the axial end portion of copper bar, and the end of copper bar is stretched in this slotted eye 8, and the connecting end surface of copper bar and copper end ring is processed as serrated face 9, to increase bonding area; Described balance trim ring has the ring 5-2 that turns up be connected as a single entity with it on the axial end of punching, and this ring that turns up withstands on the axial end of punching.
