Specific implementation mode
A kind of specific embodiment of the utility model is proposed as shown in Figure 1, and the Oil Guide for horizontal coal pulverizer oil leakage of main shaft fills
It sets, includes the firm banking 1 in square shape, be hinged a vertical link 2 on the firm banking 1, then vertical link 2 can be around fixation
Pedestal 1 carries out 360 ° of rotations, realizes the angular adjustment between vertical link 2 and firm banking 1, the front end of the vertical link 2
Interior priority is arranged with first axle and alters counterbalance spring 3, the first movable bar 4, then the first movable bar 4 alters compensation bullet with first axle
The elongation or compression of spring 3 and carry out up and down move linearly, the end of first movable bar 4 is hinged a transverse link 5, then institute
360 ° of rotations can be carried out around the first movable bar 4 by stating transverse link 5, realize the angle between transverse link 5 and vertical link 2
It adjusts, priority is arranged with the second axis and alters counterbalance spring 6, the second movable bar 7 in the front end of the transverse link 5, then second can
Mobile bar 7 with the second axis alter counterbalance spring 6 elongation or compression and carry out tandem movement, second movable bar 7
The detachably connected guide plate connecting rod 15 in end, the present embodiment connected by shank of bolt with nut, realizes guide plate connecting rod
15 and second the removing and installing between movable bar 7, the end of 15 and one frizing guide plate 8 of the guide plate connecting rod is hinged, then
Frizing guide plate 8 can be rotated 360 ° around hinged end, 8 trapezoidal shape of the frizing guide plate and second movable bar 7 with
One end of the horizontal plane of frizing guide plate 8 connects, the other end of the horizontal plane of the frizing guide plate 8 be equipped with one extend downwardly prominent scrape
Angle 8-1, and two endpoint horizontal distances of 8 horizontal plane of frizing guide plate should be highly consistent with the shaft shoulder 10, frizing guide plate 8
The prominent scraping angle that inclined surface is used to strike off the oil, frizing guide plate 8 that flow into the insertion of the shaft shoulder 10 end face flows into shaft shoulder jag for striking off
The oil in face.
It is so that axis is altered made of piano wire material that the first axle, which alters counterbalance spring 3, the second axis alters counterbalance spring 6
Counterbalance spring has that bullet degree is high, good toughness, is conducive to oil-guide device and meets axis to alter compensation rate, has both avoided oil-guide device due to axis is altered
Failure, is also beneficial to solve the problems, such as coal pulverizer oil leakage of main shaft.
The frizing guide plate 8 is such as the fluorine glue material made of wear-resistance and oil-resistance material, so that frizing guide plate 8 is had certain
Intensity, guarantee scrape oil leak, while preventing frizing guide plate 8 from being corroded by oil, prolong the service life.
When the utility model is used：Oil-guide device is installed on coal pulverizer, needs that there are necessary axial floats when installation
Compensation rate avoids main shaft 9 during operating because play causes oil-guide device to fail, if 9 direction of rotation of main shaft is up time
Needle, oil-guide device is mounted on the right side of main shaft 9, if 9 direction of rotation of main shaft is counterclockwise, oil-guide device is mounted on a left side for main shaft 9
Side, as shown in Fig. 2, firm banking 1 is secured by bolts in bearing housing, frizing guide plate 8 is set on the shaft shoulder 10, and contact surface
It must assure that smooth, seamless contact, there are certain angles between frizing guide plate 8 and the shaft shoulder 10, and are 90 °<Angle<180 °,
And the width of frizing guide plate 8 need to be more than or equal to the height of the shaft shoulder 10；When the oil sealing aged deterioration of main shaft 9,9 oil leak of main shaft is flow to
The shaft shoulder 10, frizing guide plate 8 is scraped oil leak by inclined surface and water conservancy diversion returns in beneath bearing housing, effectively prevents to leak
Oil is deposited on bearing housing outside, avoid by waste, to improve resource efficient, avoid base bearing burning accident and Fire accident
Occur.
Certainly, only the utility model preferred embodiment is described in detail in conjunction with attached drawing above, not
The scope of the utility model is limited with this, it is all according to equivalence changes made by the principles of the present invention, construction and structure,
It should all be covered by the scope of protection of the utility model.
