[0024] In order to make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the utility model will be further explained in detail below in combination with specific embodiments and with reference to the drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] Some embodiments of the utility model are described below in combination with the drawings to provide a sliding gear for a gearbox. Embodiment one

[0026] In combination with Figures 1-3 the drawings, the utility model provides a sliding gear for a gearbox, which comprises a sliding gear body 100, a reinforcing assembly 200 and an exchange assembly 300. The sliding gear body 100 comprises a first gear ring 101 and a second gear ring 102 at two ends, a first rack 103 and a second rack 104 arranged at the outer ends of the first gear ring 101 and the second gear ring 102, and a shift fork port 105 arranged between the first gear ring 101 and the second gear ring 102. The reinforcing assembly 200 comprises reinforcing tooth blocks 201 movably mounted at the outer ends of the first gear ring 101 and the second gear ring 102, mounting ports 202 penetratingly arranged in the first gear ring 101 and the second gear ring 102, and connecting strips 203 fixedly arranged at one side of the reinforcing tooth blocks 201. Welding ports 204 are further arranged at the outer ends of one side of the mounting ports 202. The reinforcing tooth blocks 201 are conical structures, and the connecting strips 203 are matched with the mounting ports 202.

[0027] Specifically, the sliding gear for a gearbox is a gear component that moves on an input shaft or an output shaft and realizes gear shifting through gear engagement at two ends. The reinforcing tooth blocks 201 are fixedly welded at the outer ends of the first rack 103 and the second rack 104 in the sliding gear body 100. The reinforcing tooth blocks 201 are conical structures and have a smaller size than the racks, so that the high-strength reinforcing tooth blocks 201 can replace the first rack 103 and the second rack 104 to absorb friction and impact during movement and engagement in the gearbox. The conical structure at the outer ends of the reinforcing tooth blocks 201 can also quickly move into other racks during movement, thereby improving the engagement effect. Meanwhile, the connecting strips 203 connected to the rear ends of the reinforcing tooth blocks 201 are inserted into the mounting ports 202 in the first rack 103 and the second rack 104, and are fixedly welded through the welding ports 204 at the outer sides of the mounting ports 202, so as to enhance the bending resistance and overall fixing strength of the reinforcing tooth blocks 201 on both sides during engagement, thereby improving the service life of the reinforcing tooth blocks 201. Embodiment two

[0028] Combining Figures 4-5 As shown in the embodiment, on the basis of the embodiment, the replacement assembly 300 comprises an extension column 301 fixedly arranged on one side of the second gear ring 102, a connecting port 302 arranged in the first gear ring 101, a notch 303 arranged outside the connecting port 302 at one end of the first gear ring 101, a first mounting hole 304 and a second mounting hole 305 respectively arranged in the extension column 301 and the notch 303, and screws 306 movably arranged in the first mounting hole 304 and the second mounting hole 305.

[0029] Specifically, the first gear ring 101 and the second gear ring 102 are connected through the connecting structure of the extension column 301 and the connecting port 302, so that the first gear ring 101 or the second gear ring 102 can be replaced individually when damaged, thereby avoiding the scrapping of the whole sliding gear body 100 and saving maintenance cost. The four groups of screws 306 arranged in the notch 303 outside the first gear ring 101 are mainly used for connecting and fixing the first gear ring 101 and the second gear ring 102. The reinforcing block 307 engaged in the notch 308 in the first gear ring 101 at the outer end of the extension column 301 is mainly used for strengthening the torsion resistance of the connection between the first gear ring 101 and the second gear ring 102, thereby ensuring the stability of the rotation of the first gear ring 101 and the second gear ring 102.

[0030] Working principle and use process of the utility model:

[0031] When the sliding gear body 100 in the gearbox moves left on the upper end of the input shaft through the shift fork rod, the reinforced tooth block 201 at the outer end of the first gear rack 103 outside the first gear ring 101 will first contact the gear on the upper end of the output shaft during the left movement, absorb the friction and impact in the contact, and quickly mesh with the gear through the conical structure, thereby reducing the wear of the first gear rack 103 at the outer end of the first gear ring 101 during the movement and meshing, and improving the service life of the sliding gear body 100. When the first gear ring 101 or the second gear ring 102 in the sliding gear body 100 is damaged, the four groups of screws 306 in the notch 303 can be disassembled to conveniently replace the first gear ring 101 or the second gear ring 102 individually, thereby reducing the maintenance cost.

[0032] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
