A motor is mounted on the side of the main leg, which is also mounted on the bottom of the large disc. Two auxiliary legs are respectively mounted on the bottom of the large disc, and the intermediate bearing legs are mounted between the large disc and the large cauldron. In this novel transmission structure for a large circular kiln, a lower transmission structure and an upper transmission structure are set at the two auxiliary legs for auxiliary transmission. The transmission structure contains a one-way bearing, which can effectively prevent the large cauldron gear and the large disc gear from reversing during emergency stops.

The meshing of the gears ensures the coaxiality of the large disc gear, thereby reducing wear on the stop. Furthermore, the transmission shaft on the auxiliary legs can be equipped with a synchronous pulley or other transmission auxiliary accessories, increasing the applicability of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of large circular knitting machine technology, and in particular to a novel transmission structure for large circular knitting machines. Background Technology

[0002] The transmission system of a circular knitting machine typically starts with a motor, which drives an intermediate transmission system via a synchronous belt. This synchronous belt then drives the main shaft, which in turn rotates the large disc gear and the large tripod gear. The intermediate transmission system contains a one-way bearing, which is a wear part. Once damaged, it must be replaced promptly. Otherwise, when the machine brakes suddenly, the reaction force generated by the resilience of the synchronous belt and the instantaneous reaction force generated by the sudden stop of the large disc gear and the large tripod gear will cause the large disc gear and the large tripod gear to reverse. This reversal will cause the needle heel to break. If the broken needle heel gets stuck in the needle groove, and the operator starts the machine without knowing this, it will result in a large number of knitting needles being scrapped, causing irreparable economic losses.

[0003] Furthermore, since it is a single-shaft transmission, the gear at the lower end of the main shaft meshes with the large disc gear to generate action and reaction forces. Moreover, the fit between the large disc gear stop and the large disc stop is a clearance fit (diameter fit tolerance 0.03-0.05). When the large disc gear rotates, the coaxiality will be affected to a certain extent, which will lead to increased wear on the stop near the main shaft and easily cause uneven wear between the large disc gear stop and the large disc stop. Utility Model Content

[0004] The purpose of this invention is to provide a novel transmission structure for a large circular machine in order to solve the above-mentioned problems.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model provides a novel transmission structure for a large circular machine, including a large plate, a main foot, a secondary foot, a middle support foot, and a large cauldron. A motor is installed on the side of the main foot, and the main foot is installed at the bottom of the large plate. Two secondary feet are respectively installed at the bottom of the large plate, and the middle support foot is installed between the large plate and the large cauldron.

[0007] The main foot is equipped with a main shaft transmission structure, which includes an intermediate transmission device and a main transmission shaft. The main transmission shaft is movably mounted on the large plate and passes through the middle support foot and is movably connected inside the large cauldron. A synchronous belt is provided between the motor and the intermediate transmission device for transmission, and a synchronous belt is provided between the intermediate transmission device and the main transmission shaft for transmission.

[0008] The auxiliary foot is equipped with a secondary shaft transmission structure, which includes a lower transmission structure and an upper transmission structure. The lower transmission structure includes a lower gear tooth of the secondary shaft, an upper cover, a lower cover, and an outer retaining ring. A transmission shaft is installed inside the lower transmission structure and is embedded in the lower gear shaft of the secondary shaft. The upper and lower covers are respectively installed on the large plate, and a one-way bearing connected to the transmission shaft is installed inside the upper and lower covers. The outer retaining ring is installed above the lower gear tooth of the secondary shaft. The upper transmission structure includes a bearing seat, an upper gear tooth of the secondary shaft, and a synchronous pulley. A transmission shaft is installed inside the upper transmission structure and is embedded in the upper gear shaft of the secondary shaft. The bearing seat is installed on the large tripod, and a one-way bearing is provided at the bottom of the bearing seat and is installed on the large tripod.

[0009] In the above technical solution, a lower transmission structure and an upper transmission structure are respectively set at the two auxiliary feet for auxiliary transmission. The upper and lower transmission structures contain one-way bearings, which can effectively prevent the large ding gear and the large disc gear from reversing in the event of an emergency stop. At the same time, installing the one-way bearings on the auxiliary feet allows for easy disassembly and replacement of the one-way bearings. The three gears of the two auxiliary feet and the main foot mesh with the large disc gear to ensure the coaxiality of the large disc gear, thereby reducing wear on the stop.

[0010] In one embodiment, the drive shaft installed on the lower transmission structure passes through the lower gear of the countershaft and the one-way bearing inside the upper and lower end covers, so that the lower gear of the countershaft is connected to the one-way bearing for transmission.

[0011] The drive shaft installed on the upper transmission structure passes through the upper gear of the secondary shaft and the one-way bearing at the bottom of the bearing housing, so that the upper gear of the secondary shaft is connected to the one-way bearing for transmission.

[0012] In one embodiment, the motor drives the main drive shaft through an intermediate transmission device.

[0013] In one embodiment, the large disc is provided with a large disc gear, a large disc gear stop, a large disc stop, and a wear-resistant plate. The large disc gear stop and the large disc are integrated into one structure. The wear-resistant plate is installed between the large disc gear and the large disc. The large disc gear meshes with the lower end of the main drive shaft, and the lower end gear teeth of the secondary shaft mesh with the large disc gear. In this technical solution, the large disc gear transmits power through its cooperation with the main drive shaft. Furthermore, the cooperation of the lower end gear teeth on the two secondary feet increases the coaxiality of the gear during rotation and reduces the wear of the stop. At the same time, the wear-resistant plate reduces equipment wear, extends service life, and ensures operational stability.

[0014] In one embodiment, a large cauldron gear and a head spindle are mounted on the large cauldron. The head spindle is mounted on the large cauldron, and the large cauldron gear meshes with the upper end of the main drive shaft. The main drive shaft drives the head spindle through the large cauldron gear. The upper end gear teeth of the secondary shaft mesh with the large cauldron gear. In this technical solution, the coaxiality of the gears during rotation is increased and the wear of the stop surfaces is reduced by the cooperation between the main drive shaft and the large cauldron gear, as well as the cooperation between the upper end gear teeth of the secondary shafts on the two secondary legs.

[0015] In one embodiment, the synchronous pulley is mounted on the upper end of the drive shaft. In this technical solution, the upper end of the drive shaft on the auxiliary foot can be equipped with a synchronous pulley or other transmission auxiliary accessories to increase the applicability of the equipment.

[0016] The advantages or beneficial effects of the above technical solutions include at least the following:

[0017] This utility model discloses a novel transmission structure for a large circular knitting machine. A lower transmission structure and an upper transmission structure are respectively installed at two auxiliary feet for auxiliary transmission.

Furthermore, installing the one-way bearings on the auxiliary feet allows for easy disassembly and replacement. The three gears on the two auxiliary feet and the main foot mesh with the large disc gear, ensuring the coaxiality of the large disc gear and thus reducing wear on the stop surface.
