Description

Technical Field

[0001] The utility model relates to the technical field of transmission devices, in particular to an integrated gear transmission box. Background Art

[0002] The spinning frame is a key equipment in the spinning process. It is mainly used to convert semi-finished roving or slivers into spinning bobbins through process steps such as drawing, twisting and winding. The spinning frame is usually driven by a main motor, and a transmission group is composed of several meshing gears to drive each part to complete the spinning work. The driving work of the middle roller and the rear roller of the spinning frame is also driven by several meshing gears. Since the middle roller and the rear roller of the spinning frame are generally provided with two and are located on both sides of the spinning frame, this driving mode makes the gear drive structure of the four rollers more complicated. Moreover, when one of the transmission gears fails, a lot of troubleshooting work is required to determine the damaged parts, and the damaged gear can only be replaced through complex disassembly and repair work, resulting in certain limitations in the driving work of the middle roller and the rear roller of the spinning frame.

[0012] As a preferred embodiment, in order to ensure the stability of the driving of the middle roller and the rear roller and increase the output torque, the outer diameter of the first driven gear is larger than the outer diameters of the first driving gear and the second driving gear, and the outer diameter of the second driving gear is smaller than the outer diameter of the second driven gear.

[0013] As described above, in order to further reduce the layout space of the drive device and ensure the compactness of the overall structure of the transmission box, an integrated gear transmission box is vertically provided with a partition in the middle of the box body, and the first driven gear and the second driving gear of the two groups of the drive devices are arranged in mirror symmetry with respect to the partition.

[0014] As a further preferred embodiment, the reversing device also includes a sleeve arranged on the outside of the box body, the reversing shaft is arranged through the sleeve, and the sleeve is adjustably connected to the box body up and down, and the height of the reversing shaft can be adjusted by adjusting the height of the sleeve, so that the fourth driving gear can be separated from or engaged with the first reversing gear to adjust the driving state of the middle roller, thereby ensuring that the driving work of the middle roller can proceed smoothly.

[0015] More preferably, a cover plate is movably provided at the upper end of the box body to prevent fibers from entering the box body during the spinning process and to protect the internal structure of the box body from contamination, thereby ensuring that the transmission box as a whole has a longer service life.

[0016] The beneficial effect of the utility model is that the utility model is an integrated gear transmission box, which integrates the transfer device for driving the middle roller and the rear roller in a box body, and completes the driving and rotating work of the middle roller and the rear roller through the driving device.
