Abstract

The utility model discloses a new thread-feeding machine used for welding equipments, which comprises a printing DC motor and a gear reducer, an output shaft of a printing DC motor is connected in transmission with a three-lever reducer. The utility model is provided with strong torque, smooth thread-feeding, non-slippery, no idling and great capacity to prevent inverted wire.

Description

Wire-feed motor

Technical field

The utility model relates to a kind of wire feeder, is mainly used in the wire-feed motor of welding equipment.

Background technology

Existing wire-feed motor generally adopts direct current generator and double reduction gear, and this structure exists driving moment little, and motor easily dallies, the welding wire skidding, and exist wire steady inadequately, stop the deficiency of wire inversion ability.

Summary of the invention

The purpose of this utility model is to provide a kind of driving moment big, and wire is wire-feed motor stably.

In order to achieve the above object, the utility model by the following technical solutions: a kind of wire-feed motor comprises printing direct current generator and decelerator, the output shaft of the printing direct current generator triple reduction gear that is in transmission connection.

After adopting said structure, owing to adopt printing direct current generator and triple reduction gear, the utility model driving moment is increased, motor is difficult for idle running, and welding wire is difficult for skidding, and wire is steady, stops the wire inversion ability strong.

Description of drawings

Fig. 1 is the structural representation of wire-feed motor of the present utility model.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing does explanation in further detail to the utility model.

As shown in Figure 1, wire-feed motor of the present utility model comprises printing direct current generator 1 and decelerator 2, the output shaft 1-8 of printing direct current generator 1 triple reduction gear 2 that is in transmission connection.First 2-4, second 2-8 and the 3rd 2-10 all are bearing in the casing 2-1 of decelerator 2 and the drive end bearing bracket 1-1 of printing direct current generator 1 goes up in the corresponding oiliness bearing 2-5.

As shown in Figure 1, triple reduction gear 2 casing 2-1 are fixedlyed connected with the drive end bearing bracket 1-1 of printing direct current generator 1, first 2-4, second 2-8 and the 3rd 2-10 are bearing on the drive end bearing bracket 1-1 of casing 2-1 and printing direct current generator, the gear 1-12 of motor output shaft 1-8 and first mesh from gear 2-2, first master gear 2-3 and second mesh from gear 2-6, second master gear 2-7 and the 3rd are from gear 2-9 engagement, and the output of the 3rd 2-10 stretches out outside the casing 2-1.Gear 1-12, from gear 2-2, first master gear 2-3, second from gear 2-6, second master gear 2-7, the 3rd be helical gear from gear 2-9, also can be spur gear.

As shown in Figure 1, printing direct current generator 1 comprises drive end bearing bracket 1-1, bonnet 1-2, motor output shaft 1-8, drive end bearing bracket 1-1 is provided with preceding yoke 1-3, rear magnetic yoke 1-4 is arranged on the bonnet 1-2, be fixed with armature plate support 1-7 on the motor output shaft 1-8, on the armature plate support 1-7 armature plate 1-5 is housed, armature plate 1-5 is relative with preceding yoke 1-3, the brush 1-9 that is electrically connected with lead 1-6 is housed on the bonnet 1-2, brush 1-9 is pressed on the armature plate 1-5 by spring 1-10, magnet steel 1-11 is housed on the rear magnetic yoke 1-4, and magnet steel 1-11 is relative with armature plate 1-5 gap.

As shown in Figure 1, when the utility model uses, after the energising, brush 1-9 and armature plate 1-5 conducting, armature plate 1-5 and armature plate support 1-7 rotate, drive motor output shaft 1-8 and rotate, motor output shaft 1-8 drives triple reduction gear (2) running again, and the 3rd 2-10 of triple reduction gear 2 drives wire feed rolls and rotate.
