Abstract
The utility model discloses a transmission noise detection device for an interference-free variable-load gear. The detection device comprises a tested gear installation clamp body, wherein the tested gear installation clamp body is provided with a driving transmission shaft and a driven transmission shaft for arranging a tested gear pair; the driving transmission shaft is connected with a driving motor through a first elastic shaft coupling; and the driven transmission shaft is connected with a driven motor through a second elastic shaft coupling. A direct current power supply drives the driving motor to drive a tested gear to rotate, mechanical energy output by the driven transmission shaft drives the driven motor to rotate, the driven motor runs as a generator by the reversing principle of a direct current motor, mechanical energy is transformed into electric energy and the output power of the driven motor is changed by changing the resistance value of a variable resistor, so that the aim of changing the load of the tested gear pair is fulfilled. The detection device has the advantages of simple structure, convenience in use, high detection accuracy, low manufacturing cost, reliable operation, and no interference.
Description
Technical field
The utility model relates to a kind of noiseless variable load gear drive noise detection device, belongs to gear drive noise detection device technical field.
Background technology
With manufacturing fast development of machinery and energy-conserving and environment-protective requirement, more and more to the demand of high precision, low noise gear.It is the requisite link of manufacture process that the low noise gear noise detects, and the gear drive noise measuring need be satisfied certain environment and condition: 1, relatively low environmental noise, 2, under the operating load condition.Yet existing gear drive noise detection device not only exists baroque problem, and in use, often because the interference environment noise is introduced in the load meeting of its mechanical drive or other form, causes its testing result untrue or can't detect.Therefore, the result of use of existing gear drive noise detection device still is not ideal enough.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, easy to use and accuracy of detection is higher, can not produce the noiseless variable load gear drive noise detection device of interference, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: a kind of noiseless variable load gear drive noise detection device of the present utility model, comprise tested gear sectional fixture body, on tested gear sectional fixture body, be provided with final drive shaft and the driven transmission shaft that is used to install tested gear pair, final drive shaft connects with the active motor by first spring coupling, and driven transmission shaft connects with slave motor by second spring coupling.
Above-mentioned active motor is a direct current motor, and initiatively motor drives by adjustable digital direct supply; Above-mentioned slave motor is a Dyn., and is in series with the variohm of using as load on the output terminal of slave motor.
Above-mentioned final drive shaft and driven transmission shaft are installed on the tested gear sectional fixture body by spring bearing respectively.
On above-mentioned tested gear sectional fixture body, also can be provided with the probe of noise decibel pick-up unit.
Owing to adopted technique scheme, the utility model drives initiatively by adjustable digital direct supply, and two of driven by motor are installed on final drive shaft and the driven transmission shaft respectively and intermeshing tested gear rotation, the mechanical energy of simultaneously driven transmission shaft output drives slave motor and rotates as generator operation, transform mechanical energy into electricity, thereby change the output power of slave motor by the resistance value that changes variohm, to reach the purpose that changes tested gear pair load.Through test with use proof, during device busy of the present utility model, no matter be under the nominal load situation, to move, still, can not produce any interfering noise constantly moving under the increase and decrease loading condition.Therefore, the utility model compared with prior art, that the utility model not only has is simple in structure, easy to use, accuracy of detection is high, can not produce the advantage of interference, cost of manufacture is low, the advantage of reliable working operation but also have.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Enforcement of the present utility model, the utility model is a kind of noiseless variable load gear drive noise detection device, its structural principle synoptic diagram as shown in Figure 1, this device comprises tested gear sectional fixture body 6, load onto final drive shaft 4 and the driven transmission shaft 5 that is used to install tested gear pair 11 on tested gear sectional fixture body 6, final drive shaft 4 and driven transmission shaft 5 are installed on the tested gear sectional fixture body 6 by spring bearing 7 respectively; Then final drive shaft 4 is connected with active motor 2 by first spring coupling 3, driven transmission shaft 5 is connected with slave motor 9 by second spring coupling 8; It is motor 2 employing direct current motors initiatively, and initiatively motor 2 drives by existing adjustable digital direct supply 1; Slave motor 9 adopts direct current generators, and the variohm 10 that series connection is used as load on the output terminal of slave motor 9, will convert mechanical energy to electric energy as generator operation according to the principle of reversibility slave motor 9 of direct current generator.
When using the utility model to detect the transmission noise of tested gear pair 11, earlier tested gear pair 11 is installed in respectively on final drive shaft 4 and the driven transmission shaft 5, and it is meshing with each other, then existing noise decibel pick-up unit is placed near near the tested gear sectional fixture body 6; In order to reach more accurate detection data, the probe 12 of noise decibel pick-up unit can be installed on the tested gear sectional fixture body 6 near tested gear pair 11 engagement places and get final product.
