Technical field

The utility model relates to the coiling facility of transformer coil coiling facility, especially high-power transformer coil, belongs to the transformer technology field.

Background technology

Need in the transformer production process by the coiling facility electromagnetic wire to be turned to the coil that adheres to specification, the high-power transformer coil winding be unable to do without special-purpose coiling facility especially.Be provided with main spindle box, tailstock, base in the basic comprising of existing large wound facility, main spindle box and tailstock are placed in the base two ends respectively, winding former one end is contained on the main spindle box floral disc, the other end is contained on the tailstock centre, and the floral disc rotation drives the winding former rotation, and electromagnetic wire is wrapped on the winding former.In this coiling facility, floral disc is fixed on main shaft one end, and main shaft is bearing on the main spindle box by bearing, and the rotating speed of main shaft is by the control of the gear train assembly in the main spindle box.The main spindle box of this structure type has following defective, the one, the speed change step by step of gear train assembly can't adapt to the infinitely variable speeds requirement after loop product and the production technology progress, the 2nd, be unable to do without lubricating oil when the rolling of supporting spindle or sliding bearing running, be difficult to reach in lubricated do not have and leak, in case the leakage pollution transformer coil occurs, will bury hidden danger of quality to transformer coil, for this reason, main spindle box in reply existing large-scale coiling facility, the especially formation improves, and makes it overcome above-mentioned defective.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of coil winding machine that is used for the high-power transformer coil, and this machine should be able to be realized the disadvantage of infinitely variable speeds and unlubricated oil leakage.

The alleged problem of the utility model realizes with following technical scheme:

A kind of coil winding machine that is used for the high-power transformer coil, be provided with main spindle box 1, tailstock 2 and base 3 in the formation, main spindle box and tailstock are placed in the base two ends respectively, main shaft 4 and drive system are arranged in the main spindle box, floral disc 13 is positioned at front-end of spindle, after the improvement, the bearing of described main shaft 4 is a self-lubricating bearing 5,6, and described drive system is in transmission connection by variable-frequency motor 7 and decelerator 8 and forms.

The above-mentioned coil winding machine that is used for the high-power transformer coil, described main spindle box adopts the boxboard Welding Structure, the self-lubricating bearing 5 of main shaft 4 front ends is placed on the double-deck tank wall 16 of casing front end, the self-lubricating bearing 6 of rear end is placed in the cross support set 9, the four-bladed vane 10 of cross support set 9 respectively with the tank wall and the gusset welding of casing.

The above-mentioned coil winding machine that is used for the high-power transformer coil is in transmission connection by shaft coupling 11 between described variable-frequency motor 7 and the decelerator 8, and the output shaft of decelerator 8 is by 14 engagements of the ring gear on pinion 12 and the floral disc 13.

The above-mentioned coil winding machine that is used for the high-power transformer coil, described decelerator 8 is the cycloidal-pin wheel decelerator.

The utlity model has following characteristics:

1. the stepless speed variator system of main spindle box transmission adopted variable-frequency motor and reductor composition has shortened driving-chain, has reduced to take up room, and has satisfied the infinitely variable speeds instructions for use in the transformer coil winding;

2. the bearing of main shaft adopts self-lubricating bearing, the disadvantage of unlubricated oil leakages, and therefore simplified the structure of main spindle box greatly, and make main spindle box can adopt extremely easy boxboard Welding Structure, can so reduce the difficulty of processing and the manufacturing cost of main spindle box;

The suitable coiling facility as wire rod coiling facility, especially high-power transformer coil of the utility model uses.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is a main spindle box A-A cutaway view among Fig. 1.

The parts label is among the figure: 1-main spindle box, 2-tailstock, 3-base, 4-main shaft, 5, the 6-self-lubricating bearing, 7-variable-frequency motor, the 8-decelerator, 9-cross support set, 10-four-bladed vane, 11-shaft coupling, 12-pinion, the 13-floral disc, 14-ring gear, the double-deck tank wall of 15-, 16-guide rail, 17-carrying roller.

Embodiment

Consult accompanying drawing.Main spindle box 1 is fixed in the left end of base 3, and tailstock 2 is fixed on right-hand guide rail 16 of base 3, can regulate the spacing with floral disc 13 along guide rail 16 straight skiddings.Main shaft 4, is in transmission connection with the drive system of being made up of variable-frequency motor 7 and decelerator 8 in main spindle box 1 by forward and backward self-lubricating bearing 5,6 swivel bearings.Self-lubricating bearing 5,6 is the solid embedded bearing, is matrix with the metal material, and adopting graphite or molybdenum bisuphide is kollag.

After main shaft 4 adopted self-lubricating bearings, unlubricated oil in the main spindle box also need not to consider the sealing leak problem of lubricating system the body structure of main spindle box to be tending towards simply, and main spindle box can adopt the welding box-shaped structure of boxboard.Back self-lubricating bearing 6 load-bearing are big relatively for preceding self-lubricating bearing 5, the preceding tank wall at preceding self-lubricating bearing 5 places is double-deck tank wall 16, with reinforcement rigidity and weight capacity, the cross support set 9 of back self-lubricating bearing 6 directly welds with gusset with the case of casing by four-bladed vane 10 and is connected.

Can be in transmission connection by shaft coupling 11 between variable-frequency motor and the decelerator 8, the output shaft of decelerator 8 extends to outside the casing, and the pinion 12 on the elongated end is meshed with major diameter ring gear 14 on the floral disc 13.Decelerator 8 can adopt the cycloidal-pin wheel decelerator.
