Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be described in more detail below by way of example with reference to the accompanying drawings:
combine figure 1, the utility model discloses constitute by increasing gear box high-speed axle 1, diaphragm coupling 2, end cap 3, experimental main shaft 4, changeover shaft 5, binding post 6, sealed lid 7.
The diaphragm coupling 2 is connected with the high-speed shaft 1 of the speed increasing box and the test main shaft 4, the diaphragm coupling and the test main shaft 4 are in conical interference fit and locked by the plug 3, the test main shaft 4 is in conical interference fit with the adapter shaft 5, the wiring terminal 6 is arranged in the test main shaft 5, and the sealing cover 7 is locked on the test main shaft 7.
The temperature sensor for measuring the temperature of the inner ring of the bearing is arranged in the adapter shaft 5, the wiring terminal 6 is arranged in the test main shaft 4, and when the test bearing is replaced, only the adapter shaft 5 needs to be replaced without detaching the test main shaft 4; the temperature sensor lead wire connects in binding post 6, and binding post 6 other end lead wire leads to shaft coupling awl flange through 4 holes of experimental main shaft, and two awl fitting surfaces are locked with end cap 3, and the lead wire is drawn forth to installing in shaft coupling awl flange through the pin hole that the equipartition set up on the awl flange. The high-speed shaft 1 of the speed-increasing gearbox is connected with the test main shaft 4 through the diaphragm coupling 2, the bearing diaphragm coupling and the test main shaft are in conical interference fit, the transfer shaft and the test main shaft are in conical interference fit, the conical interference fit can better guarantee the concentricity of two shaft sections, the unbalance amount of the dynamic balance of a shaft system is reduced, and the critical rotating speed of the shaft system is improved.
