Abstract
The invention relates to a bearing running-in testing machine which comprises an electric spindle, wherein the electric spindle is rotatably arranged on a frame; the frame at the other side of the electric spindle is fixedly provided with a booster mounting seat, the interior of the booster mounting seat is in sliding connection with a boosting push rod, the boosting push rod and the electric spindle are arranged coaxially, the operating end of the boosting push rod is fixedly provided with a compaction disk, and in the process of testing, the compaction disk props against an outer ring body fit of a bearing to be tested; the boosting push rod is fixedly provided with a spring baffle plate; and the boosting push rod is also provided with a boosting spring, one end of the boosting spring props against the spring baffle plate, and the other end of the boosting spring props against the booster mounting seat. By using the bearing running-in testing machine provided by the invention, the quantized data of the rotating speed of the bearing can be obtained; and through running, the assembling qualification rate of the bearing can be improved, and the bearings which are unqualified in temperature rise can be tested before dispatched from the factory, thereby having direct guidance meaning to users.
Description
Technical field
The present invention relates to a kind of bearing test machine, especially a kind of bearing running testing machine.
Background technology
The major function of bearing is the rotation of supporting axial workpiece, and main quality index has the limit speed of bearing, the volume load of bearing, and the rotating speed of bearing and the relation of temperature rise are: when the rotating speed increase, bearing can generate heat, and temperature raises, and rotating speed is high more, and Wen Changyue is high.
When bearing temperature rise reached the ultimate temperature of regulation, the bearing rotating speed can not improve again, if raising speed once more, temperature will continue to rise, and bearing will be burnt out, the bearing rotating speed that can reach at this moment, and we are called limit speed.
The bearing limit speed is relevant with the size of the rolling body of design bearing, and is relevant with the lubricating system and the type of cooling, relevant with the manufacturing accuracy of bearing, generally representes N=K10 with the DM value
6/ Dm, bearing are in practical work process, owing to receive the restraint of labour rotating speed of cooling condition generally can only get 70% of limit speed, and grease lubrication can only be got 70% of oil lubrication.
At present, along with customer requirements is increasingly high, the rotating speed of bearing and life requirements are also increasingly high, and the Universal Problems of high-speed bearing existence at present is a problem of temperature rise, and rotating speed does not increase.So, be badly in need of a kind of machine that can test bearing rotating speed (especially limit speed).
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of bearing running testing machine is provided.
According to technical scheme provided by the invention; Said bearing running testing machine, it is included in rotates the electric main shaft of installing on the frame, on the frame of electric main shaft opposite side, be installed with the assistor mount pad; In the assistor mount pad, slidely connect afterburning push rod; Described afterburning push rod is coaxial setting with electric main shaft, is installed with compression plate in the working end of afterburning push rod, and the outer ring body that described compression plate is against bearing to be tested at the trial cooperates; On afterburning push rod, be installed with spring stop; Also be provided with the installation energizing spring, an end of described energizing spring is against on the spring stop, and the other end of energizing spring is against on the assistor mount pad.
On the assistor mount pad, be hinged with the blanking rocking bar, described blanking rocking bar cooperates with spring stop.On frame, be provided with infrared thermometer.
The present invention can draw the rotating speed quantized data of bearing, through running-in, can improve the installation qualification rate of bearing, can the defective bearing of temperature rise detected before dispatching from the factory simultaneously, and the user is had direct directive significance.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is a left view of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: this bearing running testing machine; It is included in and rotates the electric main shaft of installing 2 on the frame 1; On the frame 1 of electric main shaft 2 opposite sides, be installed with assistor mount pad 3, in assistor mount pad 3, slidely connect afterburning push rod 4 through sliding sleeve, described afterburning push rod 4 is coaxial setting with electric main shaft 2; Be installed with compression plate 5 in the working end of afterburning push rod 4, the outer ring body that described compression plate 5 is against bearing to be tested at the trial cooperates; On afterburning push rod 4, be installed with spring stop 6; Also be provided with energizing spring 7 is installed, an end of described energizing spring 7 is against on the spring stop 6, and the other end of energizing spring 7 is against on the assistor mount pad 3.
On assistor mount pad 3, be hinged with blanking rocking bar 8, described blanking rocking bar 8 cooperates with spring stop 5.On frame 1, be provided with infrared thermometer 9.
To the bearing axle of electric main shaft 2, bearing axle and electric main shaft 2 armature spindles are fixedly linked with Bearing Installation to be tested.The effect of afterburning push rod 4 and compression plate 5 is that bearing to be tested is pushed away, and bearing to be tested is not fallen down in the process that runs up.The electric cabinet of installing on the frame 1 10 is used to set the rotating speed of electric main shaft 2 and receives handles the temperature that infrared thermometer 9 records; When the temperature that records when infrared ray temperature measurer 9 is higher than design temperature and rotating speed and does not reach design speed; Electric cabinet 10 makes electric main shaft 2 stop operating, and the bearing of being surveyed is defective bearing.When the temperature that records when infrared ray temperature measurer 9 was lower than design temperature and rotating speed and has reached design speed, the bearing of being surveyed was qualified bearing.
