Problems solved by technology

[0002] At present, the spiral bevel gear on the reduction box of domestic electric forklift adopts the positioning method of centering the tooth side of the involute spline. With this positioning method, when the forklift is heavily loaded, the spiral bevel There is a certain gap and radial runout in the key positioning, and the positioning of the spiral bevel gear is deformed, which makes the gearbox produce abnormal noise or excessive noise

Abstract

The invention relates to a gradient detection device on the basis of a single chip microcomputer. The gradient detection device comprises a gradient detector (2) and an acceleration sensor (3) mounted in the gradient detector. An acceleration signal of the acceleration sensor (3) is transmitted to the single chip microcomputer (4); the single chip microcomputer (4) is electrically connected with a resetting circuit (7), an oscillating circuit (6), a key circuit (5), an RS232 serial port downloading circuit (10) and a liquid crystal display (1); the single chip microcomputer (4) transmits the acceleration signal to an SD (Secure Digital) storage card (8) and a PC(Personal Computer)upper computer (9). The gradient detection device is low in production cost and high in accuracy, is a micro digital display intelligent road slope detector for detecting an inclination angle of a road, improves automation of industrial production and modernization of management, takes effects of shortening the operation time, improving the operation conditions and reducing use of manpower and material resources and saves cost.

Description

Technical field: [0001] The invention relates to the technical field of detection equipment, and more specifically relates to a road gradient detector. Background technique: [0002] At present, the spiral bevel gear on the reduction box of the domestic electric forklift adopts the positioning method of centering the tooth side of the involute spline. With this positioning method, when the forklift is heavily loaded, the spiral bevel There is a certain gap and radial runout in the key positioning, and the positioning of the spiral bevel gear is deformed, which makes the gearbox produce abnormal noise or excessive noise. [0003] The involute spline and outer circle positioning are now used to improve the positioning accuracy of the spiral bevel gear. When the forklift is heavily loaded, the positioning of the spiral bevel gear will not be deformed, and the noise generated by the gearbox will be reduced. Invention content: [0004] The purpose of the present invention is t...
