The metric gears are connected to a flexible shaft. When the front wheel rotates, it drives the bushing to rotate, and the bushing drives the metric gears to rotate synchronously. The flexible shaft is connected to the instrument panel, and it transmits the number of rotations of the metric gears to the instrument panel. The instrument panel converts the number of rotations of the shaft into the corresponding mileage.

[0003] Application number CN202420302919.5 discloses a mechanical meter gear. This utility model discloses a mechanical meter gear, belonging to the field of meter gear technology. It solves the problem that existing devices require the meter gear and wheel to be removed together when changing the internal lubricating oil of the meter gear, which is cumbersome to use. It includes an integrally formed worm gear housing and worm housing. The inner side of the worm gear housing is fitted with an annular worm gear through a bearing ring. The inner side of the worm housing is fitted with a worm through a bearing ring, which is connected to the instrument panel and meshes with the worm gear. The top surface of the worm housing is fixedly installed with an oil injection pipe connected to it. The side wall of the worm gear housing is fixedly installed with an oil drain pipe connected to it. Lubricating oil can be added to the inside of the worm housing through the oil injection pipe to lubricate the worm and worm gear. The lubricating oil inside the worm gear housing and worm housing can be drained through the oil drain pipe, which achieves the purpose of facilitating the replacement and addition of lubricating oil inside the worm gear housing and worm housing, making it convenient and quick to use.

[0004] This mechanical meter gear configuration includes an integrally formed worm gear housing and worm housing. An annular worm gear is rotatably mounted on the inner side of the worm gear housing via a bearing ring. A worm, connected to the instrument panel via a flexible shaft and meshing with the worm gear, is rotatably mounted inside the worm housing via a bearing ring. An oil injection pipe connected to the top surface of the worm housing is fixedly installed, and an oil drain pipe connected to the inner surface of the worm gear housing is fixedly installed on its side wall. Lubricating fluid can be added to the inside of the worm housing through the oil injection pipe to lubricate the worm and worm gear. The lubricating fluid inside the worm gear housing and worm housing can be drained through the oil drain pipe. Existing technologies have issues with replacing and adding lubricating oil. The closest existing technology has solved the problem of replacing and adding lubricating oil, but this mechanical meter gear requires maintenance and replacement after prolonged use. This device requires disassembling the entire housing for maintenance and replacement, leading to difficulties in the operation. Therefore, we propose a modified meter gear to solve the above problems. Utility Model Content
