Abstract
The utility model relates to a guide wheel structure of a tension device, which belongs to the technical field of special tooling for transformer manufacturing. The technical scheme is that the guide wheel structure comprises a wheel body (1) and a bearing (2), wherein the wheel body made of epoxy resin is arranged on the bearing; and the internal diameter of the bearing is smaller than that of the wheel body. The utility model has the benefits that as the wheel is made of epoxy resin of which the hardness lies between that of copper and that of nylon, a lead wire can not be scratched and the wheel can not be easily damaged. The guide wheel structure of the tension device protects the insulation of the lead wire, prevents the lead wire from being scratched, protects the wheel from being damaged due to long-term friction of the lead wire so as to rotate flexibly.
Description
Technical field:
The utility model relates to a kind of tensioning apparatus wheel design, belongs to transformer and makes the special tooling technical field.
Background technology:
At present, in transformer manufacturing firm, enamel-cover circle line take-up device and enamel-cover circle line-oriented device all are to adopt copper or nylon material, and all are that the wheel subcenter is opened the rotation that circular hole is equipped with the bolt realization wheel of corresponding size.In this case, bolt directly contacts with the internal diameter of wheel, and frictional force is arranged during rotation, and the pulling force of lead is big more, and wheel and bolt frictional force are big more, and wheel does not rotate when being easy to cause lead through wheel.After wheel does not rotate, just produce sliding friction during lead process wheel; Copper wheel is easy to scratch the paint film of enamelled wire, and nylon material is softer, and cut just appears in long-time friction back wheel surface, or even the groove of a rule, causes wheel to damage.
The utility model content:
The utility model purpose provides a kind of tensioning apparatus wheel design, does not scratch the paint film of enamelled wire, and wheel is not fragile, rotates flexibly, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
A kind of tensioning apparatus wheel design comprises wheel body, bearing, and the wheel body of epoxy resin material is arranged on the bearing, and bearing bore diameter is less than the internal diameter of wheel body.
The utility model also is provided with pad, wheel body both sides fluting, pad is arranged in the groove of wheel body both sides, fix by bolt, nut screwing clamping, during enamelled wire process wheel wheel internal diameter and bolt are compressed, owing to the internal diameter of bearing bore diameter less than wheel, bearing bore diameter and bolt produce frictional force, the bearing bore diameter side is no longer rotated, and the outside diameter of bearing rotates together with wheel under the frictional force of lead and wheel.
Good effect of the present utility model: change the material of wheel into epoxy resin, the hardness of epoxy resin can not scratch lead between copper and nylon, can not be damaged easily yet.The utility model has promptly protected wire insulation not to be scratched, and makes wheel no longer be subjected to the long-term friction of lead again and damages, and rotates flexibly.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the wheel body cross-sectional schematic of the utility model embodiment;
Among the figure: wheel body 1, bearing 2, groove 3.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
A kind of tensioning apparatus wheel design comprises wheel body 1, bearing 2, and the wheel body of epoxy resin material is arranged on the bearing, and bearing bore diameter is less than the internal diameter of wheel body.The utility model also is provided with pad, wheel body both sides fluting 3, pad is arranged in the groove of wheel body both sides, fix by bolt, nut screwing clamping, during enamelled wire process wheel wheel internal diameter and bolt are compressed, owing to the internal diameter of bearing bore diameter less than wheel, bearing bore diameter and bolt produce frictional force, the bearing bore diameter side is no longer rotated, and the outside diameter of bearing rotates together with wheel under the frictional force of lead and wheel.
Claims (2)
1. a tensioning apparatus wheel design is characterized in that comprising wheel body (1), bearing (2), and the wheel body of epoxy resin material is arranged on the bearing, and bearing bore diameter is less than the internal diameter of wheel body.
2. the tensioning apparatus wheel design according to claim 1 is characterized in that also being provided with pad, wheel body both sides flutings (3), and pad is arranged in the groove of wheel body both sides, fixes by bolt, nut screwing clamping.
