Abstract
The utility model relates to a sealed gear tester with built-in elastic shaft. A gear box is provided with an engaging gear and a test gear which are fixed on a rigid shaft, an elastic axis which is hidden in the sleeve, a test gear which is arranged on the axis end, and an engaging gear which is arranged on one end of the sleeve. The utility model has the advantages of simple structure, easy installation and adjustment, low cost, etc., so that the test gear efficiency, the bearing capacity, etc. can be determined as long as the loaded seal torque, the loaded rotation speed value and the loaded oil feeding condition are changed.
Description
The utility model relates to toothed gearing, especially a kind of closed type tooth wheel test device.
Because the power consumption of closed loading only is used for overcoming the resistance of system, its consumed power only is 1/20th of an open loading power, therefore, in present mechanical industry, adopt the closed type tooth wheel test device to measure the transmission efficiency and the load-bearing capacity of gear widely.Traditional closed type tooth wheel test device, as shown in Figure 1, in gear case 7,8, the test gear 5,6 of same gear ratios and meshing gear 5 ', 6 ', be connected with elastic shaft 4 and shaft coupling by stiff shaft 3 respectively, when load 9 pairs of meshing gears 5 of shaft coupling ', 6 ' and during test gear 5,6 imposed loads, when then each is to gear drive, constitute sealing load, motor 1 only is used for overcoming the power attenuation (as meshing loss, bearing friction loss, stirring oily loss etc.) of system by the power that shaft coupling 2 transmits.But, because two gear casees of employing must adopt shaft coupling, high-precision gear and bearing between stiff shaft, elastic shaft and gear, gives and install and debug and bring certain error, and volume is big, manufacturing cost also correspondingly improves.
The purpose of this utility model is: under the situation that keeps former test unit principle, stiff shaft, elastic shaft, test gear, meshing gear etc. all are contained in the gear case, structure is simplified widely.
The technical solution of the utility model is: it mainly comprises compositions such as motor, gear case, gear, stiff shaft, elastic shaft, shaft coupling.Install a meshing gear and a test gear on the stiff shaft in gear case respectively, elastic shaft one end and the another test gear that are built in the sleeve are connected, and two test gears are meshing with each other; Half sheet of the elastic shaft other end loads shaft coupling and is connected with the loading of the half sheet in addition shaft coupling that is fixed on sleeve one end in the gear case outside, and sleeve one end is connected with key and meshing gear, and two meshing gears are meshing with each other.
The utility model compared with prior art its advantage is:
1. owing to change the bidentate roller box into individual gears box structure form, the structure of gear test unit is simplified greatly.
2. directly gear is coaxial is connected with meshing gear, test for stiff shaft and elastic shaft, can save three shaft couplings, high-precision gear shaft and some high-precision bearings, avoids owing to install, debug trouble and the error brought.
3. elastic shaft is built in the axle sleeve, can play good overload breakage protective action.
In sum, this device has that compact conformation, volume are debug easily for a short time, low cost and other advantages, and 3 moduluses are had remarkable advantages with the efficient and the load carrying capacity test of annular wheel.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1, traditional closed type tooth wheel test device structure principle chart;
Fig. 2, closed type tooth wheel test device structure principle chart of the present utility model.
As shown in Figure 2, install respectively on the stiff shaft 3 in gear case 7 meshing gear 5 ', the test gear 5, elastic shaft 4 one ends that are built in the sleeve 8 are fixedlyed connected with test gear 6, and gear 5 is meshed with 6, the other end loads shaft coupling 9 in gear case 7 outsides with half sheet and fixedlys connected, sleeve 8 one ends are with key and meshing gear 6 ' fixedly connected, and make gear 5 ' with 6 ' be meshed, and being connected in addition on it, half sheet loads shaft coupling 9.Power directly drives stiff shaft 3 by motor 1, shaft coupling 2.
Relatively rotate an angle when two and half sheets load shaft coupling 9, and write down the sealing moment T that applies
2After, then the circulating power of case 7 interior two pairs of gears is N
2=(T
2n
2)/9550; If it is N that actuating motor is measured the output power of motor
1=(T
1n
1)/9550; Then utilize following formula:
η＝
, can record the transmission efficiency of testing gear.
In the formula: T
1---motor output torque;
T
2---the sealing moment of loading;
n
1---motor speed;
n
2---the meshing gear rotating speed.
The sealing moment that change to load and change tachometer value and fuel feeding situation can the determination test gear efficiency and load-bearing capacity and spot corrosion wearing and tearing, gummed situation.
