The change gear accessory of 31 tooth weft density wheel loom is applicable to shuttle loom equipment of GA615, 1515, 1511 and other models. It is mainly used to control the density (number) of weft yarn in the weaving process of loom production. Each loom uses one.Weft dense wheel is Shuttle loom parts,The unified part number of weft density wheel (also known as weft density wheel and change tooth) is L33. Generally, L33-31T represents 31 tooth weft density gear, with an overall diameter of 5.9 cm and an inner hole diameter of 18 mm, Same as other weft density wheels (shuttle loom).

The thickness of L33-31 weft density wheel is 21.5mm, and the modulus = 59 ÷ (31 + 2) = 1.788. The modulus of weft density wheel used in all shuttle looms is the same. On this basis, its diameter increases or decreases with the increase or decrease of the number of teeth. The selection of materials such as cast spur gear, bevel gear, helical gear and worm gear of textile machine is based on their stress and service life. The deformation of pig iron is better than that of steel, but the wear resistance is just the opposite.

The weft density wheel, a general accessory of the textile machine, cooperates with the reed to control the warp and weft density of the cloth surface. 1511 weft density wheel, 1515 change tooth and GA615 density gear are installed in the coiling device of the loom. Generally, the flat loom controls the fabric density with two wheel transmission ratio (except the towel fuzzing structure).

All kinds of loom gear accessories are distributed in the winding, let off, shuttle throwing and other structures of the loom, which plays an important role in the normal operation of the loom. The 31 tooth density changing gear is Shuttle loom parts, And the Weft dense wheel is fixed on the L00-4 cored pinion assembly, with a single weight of about 0.12 kg and 20 in each string.
