Embodiment 1

[0041] The resonance caused by the gear rotation in the original reducer is the source of vibration and noise, mainly including the resonance caused by its own rotation frequency and the resonance caused by the meshing frequency. Therefore, the criterion for judging resonance is whether the rotation frequency and meshing frequency are consistent with the natural frequency of the gear. Integer multiples coincide, the formula for calculating the meshing frequency of the large gear is as follows:

[0042] f N = Z 1 f z (1)

[0043] Among them, the f N Indicates the meshing frequency of the large gear, Z 1 Indicates the number of teeth of the large gear, the value is 301, f z Indicates the rotation frequency of the large gear;

[0044] Input the natural frequency of the 7th order to the original reducer, and the measured mode shape of the large gear at the 2nd, 3rd and 4th order natural frequency is offset vibration, and the resonance amplitudes are respectively:

Abstract

The invention discloses an anti-noise and sound-insulating device and a reducer having the same. The device comprises: a reducer casing, a reducer base, a large gear fixed on an output shaft, a pinion fixed on an input shaft, and a limit assembly. The reducer casing is fixedly connected to the reducer base, the input shaft is arranged on the front of the reducer casing, the output shaft is arranged on the back of the reducer casing, and the large gear and the pinion are meshed and connected. The invention can reduce the noise generated in the gear transmission process, reduce the external radiation of the transmission noise, and improve the noise reduction effect of the speed reducer.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a noise prevention and sound insulation device and a reducer having the same. Background technique [0002] With the increasing scale of modern industrial production, related production equipment is developing towards high speed and automation, and the difficulty and cost of maintaining and diagnosing equipment are becoming higher and higher. As an important component of mechanical equipment, the speed reducer The operating status directly affects the working quality of the unit and the safe operation of mechanical equipment. [0003] Vibration produces noise during mechanical transmission: Mechanical transmission equipment is a complex mechanical component that transforms or transmits the transmission force in different ways after scientific combination and assembly. Inside the system, there are great differences due to different transmission requirements, but its The complexi...
