Abstract
The invention discloses a bearing pedestal starting moment measuring apparatus which is characterized by comprising a measuring rod with a lever structure. A middle part of the measuring rod is connected with a rotating shaft through a deep groove ball bearing. A rotation center of the rotating shaft is a lever fulcrum. A front end of the measuring rod is a lever acting force point and is set as a measuring head which can be driven by a transition rod. A tail of the measuring rod is a lever resistance point and is provided with a pressure sensor at a corresponding position. The pressure sensor measures a pressure value of a lever resistance point position. When turning the measuring head through the transition rod, the measuring head drives the measuring rod to rotate around the rotating shaft, the pressure sensor detects the pressure value at the tail of the measuring rod, and when a lever moment arm is fixed, starting moment is calculated according to the measured pressure value and the moment arm. When press mounting of a main cone bearing is completed, measurement of bearing pedestal starting moment can be carried out, a feedback time is short, assembling efficiency can be greatly raised, and measurement accuracy is raised.

Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of bearing seat staring torque measurement mechanism being provided, to shorten feedback time, raising efficiency of assembling, and raising measurement accuracy.
The present invention adopts following technical scheme for the technical solution problem:
The design feature of bearing seat staring torque measurement mechanism of the present invention is that a measuring staff with lever construction is set, and described measuring staff is connected with rotating shaft by deep groove ball bearing at the middle part; As balance pivot be the center of rotation of rotating shaft, be set to the measuring head that can be driven by transiting rod with the front end of the measuring staff in force as lever; Afterbody correspondence position as the measuring staff of lever resistance point is provided with pressure transducer, records the force value of lever resistance point position with described pressure transducer.
The design feature of bearing seat staring torque measurement mechanism of the present invention also is:
Described measuring head is set to the axial float structure at the measuring staff front end, the fixedly connected one section spring core rod of the front end that described axial float structure is measuring staff, described measuring head is contained in the rod end of described spring core rod by the gauge head spring housing, forms the axial float structure of measuring head on described spring core rod.
Afterbody at described measuring staff arranges the swing position limiting structure, described swing position limiting structure is that afterbody and the measuring staff at described measuring staff is " ten " word one cuphead pilotage is set, one end pin head of described cuphead pilotage is butted on limit base by stage clip, the other end of cuphead pilotage is butted on limited block, and the spacing position of adjusting piece adjustment limited block is arranged, to adjust the swing gap of measuring staff.
When stirring measuring head by transiting rod, measuring head drives measuring staff and rotates around the axis, and pressure transducer detects force value at the afterbody of measuring staff, in the fixing situation of lever arm of force, can calculate the size of staring torque according to the force value that records and the arm of force.Compared with the prior art, beneficial effect of the present invention is embodied in:
The present invention can carry out the measurement of bearing seat staring torque when finishing the main cone bearing press mounting, feedback time is short, can greatly improve efficiency of assembling, and improves measurement accuracy.
