Description
Technical field
The present invention relates to sliding bearing field, and in particular to the sign instrument of sliding bearing intermediate bushing contact angle.
Background technology
When sliding bearing does not work, the central angle corresponding to contact surface between lower bearing and axle journal is referred to as bearing shell and contacted
Angle.Bearing shell contact angle be influence bearing shell normal operation an important parameter, need in theory by bearing shell contact angle control 60 °~
Between 90 °, and bearing shell contact angle need to be located at the middle part of lower bearing；When lower bearing repairs, maintenance personal can be according to lower bearing
The degree of wear scrape a watt amendment bearing shell contact angle, it is therefore an objective to the rubbing surface between lower bearing and axle journal is more likely formed oil film,
Reduce abrasion.Maintenance personal is firstly the need of position of the theoretical bearing shell contact angle on lower bearing is confirmed in real operation, then
Actual bearing shell contact angle is set gradually to be modified to theoretical bearing shell contact angle by scraping watt.But in face of the lower axle of different size model numbers
Watt, it is desirable to accurately indicating the theoretical bearing shell contact angle corresponding with the lower bearing has certain difficulty, and service worker is often
Actual bearing shell contact angle by virtue of experience can only be modified to the theoretical bearing shell contact angle that he thinks, so easily cause bearing shell to be repaiied
Manage that precision is not high, oil film establishes that bad, vibration is big, temperature rise situation occurs after a repair so as to trigger bearing shell.
The content of the invention
The technical problems to be solved by the invention are：One kind, which will be provided, can accurately indicate theoretical bearing shell contact angle in lower axle
The bearing shell contact angle sign instrument of position on watt.
In order to solve the above problems, the technical solution adopted by the present invention is：Bearing shell contact angle indicates instrument, is characterized in：
Including line slideway, the downside of line slideway is straight plane, sliding block is provided with line slideway, in the bottom of sliding block
It is provided with a pair of bottom same points for being articulated with sliding block and can be with two laser survey scales to the laser survey scale of both sides folding, sliding block
Slided along line slideway.
Further, foregoing bearing shell contact angle sign instrument, wherein：Line slideway is provided with scale.
Further, foregoing bearing shell contact angle sign instrument, wherein：It is provided with sliding block and represents its length direction
The graticule at midpoint.
Further, foregoing bearing shell contact angle sign instrument, wherein：The pin joint that two laser survey scales are hinged is located at
The underface of graticule.
Further, foregoing bearing shell contact angle sign instrument, wherein：Two laser can be measured by being provided with the bottom of sliding block
The bevel protractor of angle between scale.
Advantages of the present invention is：The bearing shell contact angle sign instrument can accurately indicate theoretical bearing shell contact angle in lower axle
Position on watt, enable maintenance personal scraping watt-hour with reference to the theoretical bearing shell contact angle indicated to correct actual bearing shell contact
Angle, precision is repaired so as to substantially increase bearing shell.
Brief description of the drawings
Fig. 1 is the structural representation that bearing shell contact angle of the present invention indicates instrument.
Embodiment
With reference to specific embodiments and the drawings, the present invention is described in further detail.
Bearing shell contact angle indicates instrument, as shown in figure 1, including line slideway 1, the downside of line slideway 1 is straight
Plane, sliding block 2 is provided with line slideway 1, a pair of bottom same points for being articulated with sliding block 2 are provided with the bottom of sliding block 2
And it can be slided to the laser survey scale 3 of both sides folding, sliding block 2 with two laser survey scales 3 along line slideway 1.
In the present embodiment, line slideway 1 is provided with scale.It is in order that sliding block 2 can be slided exactly to set scale
Move the middle part of lower bearing 4；The graticule 21 for representing the length direction midpoint of sliding block 2, the phase of two laser survey scale 3 are provided with sliding block 2
Mutually be hinged pin joint is located at the underface of graticule 21, sets graticule 21 to be in order that can be with graticule 21 for ginseng when sliding 2 slip
Examine and accurately draw the distance of slip.The bevel protractor of angle α between two laser survey scales 3 can be measured by being provided with the bottom of sliding block 2
5, set bevel protractor 5 that maintenance personal can be made more intuitively to find out the angle between two laser survey scales 3, facilitate maintenance personal to adjust
α angles.
The operation principle of bearing shell contact angle sign instrument is described in the present embodiment：Bearing shell is contacted footmark by maintenance personal first
Show that instrument is placed on the upper surface of lower bearing 4, now ensure that the upper surface of the lower plane and lower bearing 4 of line slideway 1 is close
Fitting, then according to the scale sliding slider 2 on line slideway 1 to the middle part of lower bearing 4, swash further according to the adjustment of bevel protractor 5 two
Then angle between optical scale 3 opens two laser survey scales 3, now the meeting on the inner surface circular arc of lower bearing 4 to required angle
There is a twice laser mark, the central angle corresponding to circular arc in twice laser mark is theoretical bearing shell contact angle, maintenance personal
With regard to that can carry out scraping a watt amendment to lower bearing 4 using the theoretical bearing shell contact angle as reference.
Beneficial effects of the present invention are：The bearing shell contact angle sign instrument can accurately indicate theoretical bearing shell contact angle and exist
Position on lower bearing, maintenance personal is set to be connect with reference to the theoretical bearing shell contact angle that indicates to correct actual bearing shell scraping watt-hour
Feeler, precision is repaired so as to substantially increase bearing shell.
