Description
Affiliated technical field
The utility model relates to the testing apparatus of large-scale turntable bearing, particularly a kind of charger of shield structure main bearing axial force.
Background technology
Shield machine is the main construction machinery in the underground driving shield-tunneling construction, has obtained using widely in the large tunnel engineering projects such as present city underground in China, mistake river vcehicular tunnel, tunnel over strait.The shield machine main bearing is the core component of shield machine, plays a part to support shield cutter and make it to turn round brokenly rock.Main bearing mainly adopts internal-gear type three-row roller combination dials bearing, bears respectively radially, axial load and upsetting moment, reaches designed life more than 10,000 hours.When headwork, respectively drive a pinion wheel by several variable frequency drive motors or oil motor, pinion wheel and bearing engagement drive the cutterhead rotation.The main bearing that destroys need hang out replacing from shield machine top excavating shaft, and difficulty is very big, will bring immeasurable loss to construction.Therefore, it is very necessary that the shield machine main shaft is made the test of axial loading and radial loaded, and the development that the test figure that draws can be product provides important reference frame with exploitation.
Summary of the invention
The purpose of the utility model is to solve the axial force loading problem of above-mentioned bearing, provides a kind of and can simulate bearing carries out the shield structure main bearing axial force of axial load test in real work charger.
Realize that the utility model purpose technical scheme is: described charger comprises lathe bed, fixed panel, shield structure main bearing, loading arm, motor; Lathe bed and fixed panel tighten up; Shield structure main bearing outer ring and fixed panel are fixed through high-strength bolt; The shield structure main bearing outside from inside to outside is followed successively by pressing plate, thrust bearing and web joint; Pressing plate, thrust bearing and web joint are fixed as one through bolt and shield structure main bearing inner ring, and loading arm and web joint are fixed, and axial load cylinder is set on fixed panel; Gear shaft is set on lathe bed, and gear shaft one end is provided with tooth engagement on pinion wheel and the shield structure main bearing inner ring, and the other end is provided with the bevel gear engagement on bevel gear and the splined shaft, and splined shaft is connected with motor.
