Description

Gear transmission clutch device of warp knitting machine Technical Field The utility model relates to the field of warp knitting machines, in particular to a gear transmission clutch device of a warp knitting machine. Background In warp knitting machines, a common transmission structure is to realize the transmission between the gear a and the gear B through a carrier gear. Moreover, due to the working requirements, it is required that the carrier gear can be switched between the engaged and the disengaged state, for which purpose clutch means are added. The existing gear transmission clutch device generally comprises a shaft sleeve and a carrier gear rotatably arranged on the shaft sleeve through a bearing, wherein a bolt is coaxially and movably arranged in a central shaft hole of the shaft sleeve, the head end of the bolt is a free end, the tail end of the bolt is a fixed end, the outer shaft end of the shaft sleeve can be limited through the head of the bolt, the tail end of the bolt is fixedly connected with a connecting plate through a nut, and a spring is sleeved on the bolt and connected between the shaft sleeve and the connecting plate. When the device works, the shaft sleeve is parallel to the gear shafts of the gear A and the gear B, the shaft sleeve is positioned between the gear A and the gear B, and the axial movement of the carrier gear is controlled by screwing in or screwing out a bolt from the connecting plate and utilizing the compression and the extension of the spring, so that the carrier gear is converted between the engaged state and the disengaged state of the gear A and the gear B. However, the existing control method has a plurality of inconveniences, such as the need of frequently and manually adjusting the bolt, complex and time-consuming operation, and in addition, the control precision is unstable due to the elastic change of the spring, so that the operation difficulty is further increased. Disclosure of utility model The utility model aims to provide a gear transmission clutch device of a warp knitting machine. The technical scheme for realizing the aim of the utility model is as follows: a gear transmission clutch device of a warp knitting machine comprises a shaft and a carrier gear arranged on the shaft; one end of the shaft is a fixed end, and the other end of the shaft is a free end; A shaft sleeve is rotatably sleeved at the middle part of the shaft, a first step for mounting a carrier gear is arranged on the peripheral surface of the shaft sleeve, and the carrier gear is rotatably mounted on the shaft sleeve through a bearing; The shaft sleeve is provided with a radial threaded hole, a spiral guide groove extending along the axial direction is formed in the outer circumferential surface of the shaft, a screw is screwed in the radial threaded hole, the inner end of the screw is movably inserted into the guide groove, the outer wall of the shaft sleeve is fixedly connected with a handle, and the handle is shifted to enable the shaft sleeve to rotate and drive the inner end of the screw to slide along the guide groove. According to the utility model, the shaft sleeve, the bearing and the carrier gear can rotate on the shaft together through the toggle handle, meanwhile, as the screw is matched in the radial threaded hole of the shaft sleeve and the inner end part of the screw is movably inserted into the guide groove, the inner end part of the screw can be driven to slide reciprocally along the guide groove while the shaft sleeve rotates, so that the stable axial movement of the carrier gear can be realized through the toggle handle, and the conversion between the carrier gear and the gears A and B in the disengaged and meshed state can be realized. The gear transmission clutch device of the warp knitting machine has the advantages of convenience in engagement and disengagement, rapidness, high efficiency and stable and reliable performance.
