Abstract
The utility model provides a main transmission device of a band saw for metal and specifically relates to a main transmission device, powered by a curved linear motor, of a saw. The main transmission device of the band saw for metal is composed of a main belt wheel, a main shaft, an end cover, a bearing block, a bearing, a saw frame, a copper bush, a motor secondary side, a primary winding and a primary iron core. If the power is increased, double main transmission devices can be adopted, and a frequency converter can be used for realizing stepless speed regulation. The device is powered by the curved linear motor, components such as a speed reducing mechanism are omitted, and the purposes of improving the transmission efficiency, reducing the noise, reducing the volume, reducing the weight and saving the production cost are achieved.
Description
Technical field
The utility model relates to band saw machine field, relates in particular to a kind of band saw for metal main drive.
Background technology
Existing band saw machine main transmission, is slowed down through V-shaped band and gear reduction unit by alternating current generator, drives main pulley to rotate.There is complex structure in this transmission system, volume is larger, Heavy Weight, the drawback such as transmission efficiency is low, and noise is large.
Utility model content
The drawback existing in order to overcome above-mentioned existing band saw machine main transmission, the technical scheme of a kind of band saw for metal main drive of the utility model is: adopt the band saw for metal main drive that arc linear motor is power, it is made up of main pulley, main shaft, end cap, bearing block, bearing, saw frame, copper sheathing, motor secondary, armature winding, elementary iron core.
Two bearing blocks are fixedly mounted on respectively saw frame two sides, and main shaft and two bearings are arranged in bearing block, and two end cover screws are fixedly mounted on respectively on bearing block.
Main pulley is fixedly mounted on the left end of main shaft.
Motor secondary is fixedly mounted on the right-hand member of main shaft, and copper sheathing is arranged in motor secondary; Elementary iron core is fixedly mounted on saw frame with bolt, and armature winding is inlaid in the groove of elementary iron core.
A kind of band saw for metal main drive of the utility model, employing arc linear motor is power, has save the parts such as reducing gear, improves transmission efficiency, reduces noise, reduces volume, weight reduction, saves production cost.
If add high-powerly, can adopt two main drives, use frequency converter can realize stepless speed regulation.
Accompanying drawing explanation
Accompanying drawing is the utility model structural representation.
