Abstract
A synchronous belt pulley with a pin shaft groove mainly includes a belt pulley flange, a transmission shaft hole, the pin shaft groove, a fixed-end shaft shoulder, and transmissions shaft tightening screw holes, wherein a pin shaft groove is arranged in the transmission shaft hole, the fixed-end shaft shoulder is arranged on a side of the belt pulley flange, and two transmission shaft tightening screw holes are formed on the fixed-end shaft shoulder and distributed on the periphery of the shaft shoulder at an angle of 90 degrees.
Description
(1) technical field
The utility model relates to a kind of synchronous pulley device of embroidery machine main drive shaft, is specifically related to a kind of synchronous pulley with the bearing pin groove.
(2) background technique
Embroidery machine is in the embroidery process, the transmission of power of each head mainly relies on a major axis to come transmission by synchronous belt, and synchronous pulley is fixed on the transmission shaft at each head rear by certain way, for balance and the unification that realizes each head transmission of power, synchronous pulley is installed in should be firm on the transmission shaft, do not allow frequent rotation because of machine phenomenon such as to be subjected to displacement.For the embroidery machine kind of some multimachine heads, whether what head moved seems extremely important synchronously, so the installation effect of synchronous pulley is very crucial.General synchronous pulley all is simply to be installed on the transmission shaft, fixed by screw and set screw, this synchronous pulley be applied to the few type of head quantity also can, but the type that is applied to the multimachine head seems that then using effect is undesirable.
(3) summary of the invention
Problem to be solved in the utility model provides a kind of synchronous pulley that has the bearing pin fixation, and main technical schemes is as follows:
A kind of synchronous pulley with the bearing pin groove, mainly comprise belt wheel wheel rim, transmission shaft axis hole, bearing pin groove, the fixed end shaft shoulder, transmission shaft screw hole, be provided with the bearing pin groove in the transmission shaft axis hole, belt wheel wheel rim one side is provided with the fixed end shaft shoulder, the fixed end shaft shoulder is provided with two transmission shaft screw holes, and the screw hole is 90 ° of angles and is distributed on the shaft shoulder circumference.
The synchronous pulley of band bearing pin groove described in the utility model, device is simple, and is reasonable in design.The bearing pin groove set-up mode that it is unique, reaching each synchronous pulley all has two screw holes, helps synchronous pulley fixing with spacing on transmission shaft, and phenomenons such as skidding of synchronous pulley can not take place because of the inefficacy of screw.
