Abstract
The utility model belongs to mechanical detection field more particularly to a kind of device of test bearing staring torque.It include: adapting rod (1), sleeve (2) and nut (3), by using the device of the utility model test bearing staring torque, bearing staring torque value is measured by torque spanner, staring torque is unable to measure after solving the problems, such as bearing installation, the apparatus structure is simple, it is easily achieved, is promoted convenient for a wide range of.
Description
Technical field:
The utility model belongs to mechanical detection field more particularly to a kind of device of test bearing staring torque.
Background technique:
Bearing staring torque refers to what the inside and outside circle of bearing overcame required for the moment that stationary state is relatively rotated to
Frictional resistance moment is easy to deform bearing outer ring when bearing Rig up error, significantly affects the size of staring torque.Bearing opens
Flexibility after kinetic moment size concentrated expression bearing installation is the important technology index that bearing installation is judged, the index
Measurement is always the problem of world's bearing industry, lacks simple and easy bearing staring torque measurement method, specification and device.
Summary of the invention
The utility model is directed to the status that bearing staring torque is unable to measure, using a kind of dress of test bearing staring torque
It sets.
The technical solution adopted in the utility model is a kind of device of test bearing staring torque, which is characterized in that packet
Include: adapting rod 1, sleeve 2 and nut 3,1 outer circle of adapting rod are in Step Shaft, and big end is in flat-shaped, and large end face has square hole, with power
The cooperation of square spanner square head, small end have screw thread, connect with nut 3, threaded upper portion staight shank and brearing bore clearance fit；The set
2 outer diameters of cylinder are not less than bearing inner race boss outer diameter, and internal diameter and 1 small end thread pitch of adapting rod cooperate.
The 1 outer circle guide portion of adapting rod is multi-stage stairs axis, can be cooperated with different size brearing bore.
The nut 3 is standard six square nuts.
Beneficial effects of the present invention are, by using the device of test bearing staring torque of the present invention, to pass through torque spanner
Bearing staring torque value is measured, staring torque is unable to measure after solving the problems, such as bearing installation, and the apparatus structure is simple, is easy to
It realizes, is promoted convenient for a wide range of.
Detailed description of the invention
Fig. 1 is a kind of device sectional arrangement drawing of test bearing staring torque
Wherein, 1: adapting rod, 2: sleeve, 3: nut；
Fig. 2 is a kind of device assembling plan view of test bearing staring torque
Fig. 3 is adapting rod axonometric drawing
Specific embodiment
It for better implementation the utility model, elaborates, asks to the utility model with reference to the accompanying drawings of the specification
Refering to Figure of description 1,2,3.
A kind of device of test bearing staring torque, comprising: adapting rod 1, sleeve 2 and nut 3, specific implementation step is such as
Under:
1,1 small end of adapting rod is packed into brearing bore, guide portion is slidably matched with brearing bore, and step surface develops bearing
Inner ring end face；
2, sleeve 2 is packed into adapting rod 1 in bearing other side, sleeve 2 is developed with bearing inner race end face；
3, nut 3 is screwed in into adapting rod 1 using spanner, until bearing inner race, adapting rod 1, sleeve 2, nut 3 paste completely
Tightly, it is not freely rotated；
4, torque spanner square head is inserted into 1 big end square hole of adapting rod；
5, a hand steered firmly part, another hand turning moment spanner when bearing starts turning, read torque spanner and show
Moment values, the as staring torque of bearing.
Embodiment
GE8C oscillating bearing is installed using agglomeration mode in certain rocker arm assembly one end, requires staring torque to be not more than after installation
3N.m illustrates the specific embodiment of this patent:
1, adapting rod small end is packed into brearing bore, guide portion is slidably matched with brearing bore, and step surface develops bearing
Inner ring end face；
2, sleeve is packed into adapting rod in bearing other side, sleeve is developed with bearing inner race end face；
3, nut is screwed in into adapting rod using spanner, until bearing inner race, adapting rod, sleeve, nut are adjacent to completely, do not sent out
Life is freely rotated；
4, torque spanner square head is inserted into adapting rod big end square hole；
5, a hand steered firmly rocker arm assembly, another hand turning moment spanner when bearing starts turning, read torque spanner
The moment values of display, the as staring torque of bearing.
