[0002] At present, double gear sets are used more and more frequently in the machinery industry, and the performance requirements for gears are also getting higher and higher. Most of the existing double gear sets are fixed, and the distance between the gear sets cannot be adjusted according to actual needs, so the scope of use is limited.

[0003] For example, the utility model with the patent number 202121204304.1 discloses a double gear set, which includes a first output gear, a second output gear and four inner hexagon bolts. This double gear set combines and installs the first output gear and the second output gear, which can output two speeds outward to realize the adjustment of speed. At the same time, it is convenient to disassemble and replace when one of the gears is damaged, saving costs; the use of four mounting posts facilitates the fixation of the second output gear and supports the spoke of the first output gear, enhancing the structural strength of the first output gear;

[0004] The double gear set in this patent cannot adjust the gear spacing. If there is a mismatch during the installation process, it is necessary to replace or add or subtract gears again, which increases the difficulty of gear installation and the applicability is not very strong.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , the present utility model provides a technical solution: a modular double gear set with adjustable pitch, including a first gear set 1, a second gear set 2 is arranged above the first gear set 1, a first mounting sleeve 3 is fixedly installed inside the first gear set 1, a second mounting sleeve 13 is fixedly installed inside the second gear set 2, a first connecting sleeve 4 is fixedly installed inside the first gear set 1, a second connecting sleeve 8 is fixedly installed inside the second gear set 2, an adjusting and limiting assembly 6 is installed on the first connecting sleeve 4 and the second connecting sleeve 8, a movable sleeve 5 is arranged inside the first connecting sleeve 4 and the second connecting sleeve 8, a connecting flange 11 is fixedly installed at the end of the movable sleeve 5, and the adjusting and limiting assembly 6 can drive the connecting flange 11 to move, thereby adjusting the position of the movable sleeve 5. A connecting shaft 7 is fixedly installed inside the first mounting sleeve 3, the second mounting sleeve 13 is attached to the outer surface of the connecting shaft 7, uniformly distributed rigid rollers 12 are arranged inside the movable sleeve 5, and the rigid rollers 12 are attached to the outside of the connecting shaft 7. By providing the rigid rollers 12, the contact area between the connecting shaft 7 and the movable sleeve 5 can be reduced, thereby reducing friction and the wear degree of the connecting shaft 7.

[0023] The adjustment and limit component 6 includes a limit guide rail 601. An active rod 602 is installed inside the limit guide rail 601. Positioning holes 603 are evenly distributed on the surface of the active rod 602. A pin 604 corresponding to the positioning hole 603 is arranged inside the limit guide rail 601. There are two groups of pins 604 respectively. Through the mutual cooperation between the pin 604 and the positioning hole 603, the active rod 602 can be fixed on the limit guide rail 601, realizing the flexible adjustment of the position of the active rod 602. The active rod 602 is fixedly installed outside the connecting flange 11. There are six groups of the active rod 602 and the limit guide rail 601 in total. Convex rings 14 are arranged on the surfaces of the first connecting sleeve 4 and the second connecting sleeve 8. First grooves 15 are evenly distributed on the surface of the convex ring 14. The limit guide rail 601 is fixedly installed inside the first groove 15. Limit blocks 10 are evenly distributed on the surface of the convex ring 14.

The two connecting flanges 11 are connected to each other by hexagon bolts. By providing the connecting flange 11, the two gear sets can be connected together.

[0024] During operation, first install the entire gear set structure in place. When it is necessary to adjust the distance between the first gear set 1 and the second gear set 2, the second gear set 2 can be pulled outwards. At this time, the limit guide rail 601 and the active rod 602 in the adjustment and limit component 6 where the first gear set 1 and the second gear set 2 are located are stretched, making the second gear set 2 move away from or close to the first gear set 1. During this process, the pin 604 in the limit guide rail 601 will pass through the positioning holes 603 at different positions on the surface of the active rod 602, so that the limit guide rail 601 and the active rod 602 will not separate from each other. After adjusting the distance between the first gear set 1 and the second gear set 2, then install the entire gear set at the position required by the equipment, so that the gears on the two gear sets can mesh with the gears on the equipment.
