[0026] like Figures 1-3 As shown, a divider positioning device includes a housing assembly 1, a worm gear 2 disposed inside the housing assembly 1, bearings at both ends of the worm gear 2, and one end of the worm gear 2 extending through to the outside of the housing assembly 1. A connecting flange 3 is mounted on the side of the housing assembly 1, and the other end of the worm gear 2 is mounted to the inner wall of the housing assembly 1. The surface of the worm gear 2 is provided with teeth, and a worm wheel 21 is meshed at the teeth. The teeth of the worm gear 2 are helical and mesh with the teeth of the worm wheel 21 to transmit power. A first shaft 4 and a second shaft 5 are mounted side by side on the housing assembly 1 via bearings. A large gear 6 is nested on the first shaft 4, and a small gear 7 is nested on the second shaft 5. The large gear 6 and the small gear 7 mesh with each other. The worm wheel 21 is concentrically mounted on the first shaft 4.
[0027] Furthermore, the worm gear 2 extends through to the bearing on the outside of the housing assembly 1, which is the first bearing 8, and a spacer 81 is provided on the outer end of the first bearing 8.
[0028] Furthermore, the worm gear 2 is mounted on the inner wall of the housing assembly 1, and the bearing is a second bearing 9. A retaining ring 91 for the hole is provided on the outer end of the second bearing 9. The retaining ring 91 for the hole is a resilient fastener installed in the hole, mainly used to axially fix the components and prevent them from moving axially. It is usually made of spring steel, has elasticity, can fit tightly against the hole wall, and provide a reliable fixing effect.
[0029] Furthermore, the bearing is a deep groove ball bearing, which is simple in design, easy to use, and can withstand radial and axial loads, making it suitable for high-speed applications.
[0030] Furthermore, an end cap oil seal 92 is provided on the outer end of the elastic retaining ring 91 for the hole.
[0031] Furthermore, the side of the housing assembly 1 is fitted with a connecting flange 3 via screws 101.
[0032] Furthermore, a third bearing 10 and a fourth bearing 11 are respectively installed at both ends of the first shaft 4.
[0033] Furthermore, a fifth bearing 12 and a sixth bearing 13 are respectively installed at both ends of the second shaft 5.
[0034] Furthermore, the housing assembly 1 is equipped with a screw-in circular oil level indicator 14, which is a device for monitoring the lubricating oil level of mechanical equipment. It is usually installed in the oil tank or lubrication system. It displays the oil level intuitively through a transparent window or marking line, helping operators to maintain it in a timely manner. It is screwed in by threads and is suitable for various oil tanks or lubrication systems. Circular appearance: compact structure, easy to install and observe.
[0035] Furthermore, the housing assembly 1 is equipped with an internal hexagonal plug 15, which is a fastener used to seal oil holes or oil passages. Through the internal hexagonal design, it can be installed and removed using a hexagonal wrench to ensure sealing and prevent lubricating oil leakage.
[0036] In this invention, all bearings are deep groove ball bearings. Specifically, the first bearing 8 and the second bearing 9, which are fitted together at both ends of the worm gear 2, are deep groove ball bearings; the third bearing 10 and the fourth bearing 11, which are fitted together at both ends of the first shaft 4, are deep groove ball bearings; and the fifth bearing 12 and the sixth bearing 13, which are fitted together at both ends of the second shaft 5, are also deep groove ball bearings. The use of deep groove ball bearings reduces friction loss during transmission and improves mechanical efficiency. One end of the second shaft 5 extends out of the housing assembly 1 and connects to the corresponding transmission shaft. The smoothness of transmission is enhanced through the structural cooperation of the various meshing points within the divider positioning device.
[0037] The overall principle of the divider positioning device is as follows: when the lead angle of the worm gear 2 is less than the equivalent friction angle of the meshing surface, the irreversible transmission characteristic achieves the self-locking function; then, through the transmission ratio of a pair of gear pairs, a certain transmission speed is achieved; finally, through the sensor, the output shaft is accurately positioned 360 degrees.
[0038] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
