Problems solved by technology

Although the gear rotation efficiency demonstrator is used in teaching, it does not have the function of judging the failure mode of the gear; the test cycle of the gear life test bench is long, the cost is high, and the transmission characteristics of several typical failure gears cannot be evaluated at the same time; it is mainly used in the enterprise. Gear life research is not suitable for classroom teaching requirements
Moreover, these experimental equipment related to gear transmission cannot demonstrate the vibration mode phenomenon caused by the change of gear tooth failure form in the gear transmission system, nor can it realize the experimental teaching of the influence of different gear tooth failure forms on gear transmission efficiency and transmission accuracy

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0014] The present invention is a kind of numerical control demonstrator which integrates the demonstration of gear failure, rotation efficiency and rotation precision, and can realize the teaching experiment of the transmission phenomenon after the failure form occurs in the gear transmission system. Its structure is as follows figure 1 As shown: it is mainly composed of gear failure characteristic group 1, magnetic powder clutch 14, vibration sensor 19, speed change system, motor drive system, force sensor, numerical control system and data acquisition and processing system, which are installed on the machine base 20. The gear failure feature group 1 is installed on the transmission shaft 3 , and the transmission shaft 3 is installed on the base 20 through the first bearing seat 2 and the second bearing seat 13 . The left end of the transmission shaft...

Abstract

The invention provides a numerically controlled demonstration instrument for demonstrating gear transmission failure, which comprises a gear failure characteristic assembly (1), a frame (20), a vibrating sensor (19), a magnetic powder clutch (14), a force sensor, a gear shifting system, a motor driving system, a numerical control system, and a data collection and processing system. The gear failure characteristic assembly (1) is installed on a transmission shaft (3), and the two ends of the transmission shaft are respectively installed on the frame (20) through a bearing seat. The instrument integrates gear failure, rotational efficiency and rotational precision, and is compact in structure and small in volume. Moreover, the instrument can not only demonstrate vibration mode phenomenon arising from gear failure behaviors in a gear transmission system, but also realize experimental teaching of the influence of different gear failure behaviors on gear transmission efficiency and transmission accuracy, so as to broaden the experimental contents for systematically teaching the gear transmission.

Description

technical field [0001] The invention relates to teaching equipment, in particular to a gear transmission failure numerical control demonstrator. Background technique [0002] At present, there are gear failure numerical control demonstration instruments on the domestic market, while similar products abroad are gear rotation efficiency or gear life test benches, and their working principle is to measure the power loss or gear life of gears. Although the gear rotation efficiency demonstrator is used in teaching, it does not have the function of judging the gear failure mode; the gear life test bench has a long test period and high cost, and cannot simultaneously evaluate the transmission characteristics of several typical failure gears; it is mainly used in enterprises. The research on the life of gears does not meet the requirements of classroom teaching. Moreover, these experimental equipment related to gear transmission cannot demonstrate the vibration mode phenomenon caus...
