Description
Technical field
The present invention relates to gear, rack field, more particularly to a kind of self-lubricating rack.
Background technology
Rack is that rack also divides spur rack and diagonal-cut rack with a series of flat boards or straight-bar for equidistantly distributing tooth,
Used respectively with straight spur gear and helical gears pairing.It is combined through gear drive with rack-driving, more particularly to
During linear transmission, frequently with the kind of drive of rack pinion, have the advantages that transport is steady, step pitch is calibrated, have load-carrying concurrently.In order to
Its service life can be improved by preventing the abrasion, spot corrosion, gluing of rack and pinion, and the lubrication for rack and pinion is particularly important.
In the prior art, in order to improve the cooperation transmission performance of gear and rack, often it is directly injected into lubricating oil or coating
In the way of lubricating grease, effect preferably, but obviously has the disadvantage again note before lubricating oil or lubricating grease are finished
Enter or coat, with continuous lubrication performance.Lubricating oil can directly be contained in special lubricant oil reservoir in some mechanical structures, often
It is secondary toward lubricating oil is injected in oil vessel, it is also more convenient, but this oil vessel is for the machinery and volume using lubricating grease
This length of rack and be just difficult to open up for thin structure.So, develop a kind of rack of self-lubricating and passed for rack-and-pinion
The influence of dynamic mechanical performance is huge.
The content of the invention
It is an object of the invention to provide a kind of self-lubricating rack, so that rack obtains self-lubricating property, without often adding
Plus the combination property of pinion and rack is lifted in the case of lubricating oil/lubricating grease, to solve problems of the prior art.
In order to realize the above object the technical scheme is that：
A kind of self-lubricating rack, including rack body, teeth portion, backlash, rack body are in the form of a column, and the rack body interior has
Structure chamber, the structure chamber includes oil pocket, oiling tube chamber, capillary cavity, and the oiling tube chamber is long along rack in rack body
Degree direction one end has oil filler point, and oil filler point is connected with end cap, and the oiling tube chamber connects oil pocket in rack body interior,
Oiling tube chamber also connects up capillary cavity, and capillary cavity upwardly extends and penetrates rack body upper end.
Preferably, the capillary cavity extends and penetrates backlash.Backlash open pipe chamber does not influence intensity, if teeth portion then may be used
Structural strength can be influenceed, and backlash is more convenient for installing fibrous felt.
Further, there is fibrous felt, the fibrous felt is covered and capillary cavity of fitting penetrates backlash on the backlash
The pore of formation.Fibrous felt and its cover and fit pore by the function of lubricating oil be directly directed to wetting, double profit
It is sliding.
Preferably, having upper oil pipe between the oiling tube chamber and oil pocket.The convenient export lubricating oil of upper oil pipe.
Preferably, a diameter of 50 ~ 350 μm of the capillary cavity, capillary cavity is distributed 3 ~ 8 in each backlash.Hair
Tubule chamber is meticulous not to allow easy processing, and 50 ~ 350 μm had not only facilitated processing but also can produce gratifying capillary effect, and distribution number increases
Plus uniformity.
The beneficial effects of the present invention are：Simple in construction, greasy property of the invention is good.Structure cavity configuration is fine, oil pocket, note
Oil pipe chamber, capillary cavity play a part of that a certain amount of lubricating oil can be stored jointly can timely use rack again；Capillary
Chamber can produce capillarity, be derived automatically from lubricating oil to backlash；Fibrous felt enhancing has soaked lubricating oil export, further promotes
Lubricant effect.The rack of the present invention make use of capillarity to export lubricating oil, and lubricating oil is easily realized with simple structure
" self-sufficient ", is greatly prolonged relative to the prior art lubricated maintenance cycle, and easy to use, lubricating uniform is substantially lifted
The synthesis greasy property of rack.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure：1- rack bodies, 10- structure chambers, 11- oil pockets, 12- oiling tube chambers, 13- capillary cavities, 14- oil filler points,
The upper oil pipes of 15-, 2- teeth portion, 3- backlash, 4- end caps.
Embodiment
In order to illustrate more clearly of the embodiment of the present application or technical scheme of the prior art, letter will be made to embodiment below
Singly introduce.
With reference to Fig. 1 and specific embodiment, the present invention is furture elucidated.
