Description
Technical field：
It the utility model is related to a kind of rack pinion self-lubricating device.
Background technology：
In machinery field, since rack pinion is steady, transmission efficiency, so can use rack pinion at some
Field, such as linear transmission of power etc. is driven frequently with rack-and-pinion.But rack-and-pinion is during engagement,
Tooth surface abrasion, point decorations, glued situation occurs, these situations can greatly shorten the service life of rack-and-pinion.Therefore, in time
The rack-and-pinion to transmission be lubricated it is of crucial importance.But existing rack-and-pinion lubrication is lubricated using manually smearing mostly
The mode of fat carries out, and there are the shortcomings that labour cost is high, security is low, lubricating efficiency is low for this kind of lubricating system.The prior art pair
This does not have the plan of solution.
Utility model content：
The purpose of this utility model is aiming at disadvantages mentioned above existing in the prior art, there is provided a kind of rack pinion
Self-lubricating device, it is rational in infrastructure, self-lubricating can be carried out in operation, solve problems of the prior art.
The utility model is that technical solution is used by solving above-mentioned technical problem：
A kind of rack pinion self-lubricating device, including stent, a C-channel, the C-channel are equipped with the side of stent
Including the upper plate and lower roof plate being connected with stent, a lubrication axis is consolidated through upper plate and lower roof plate and with upper plate and lower roof plate
Even, the felt lubrificated wheels are set on lubrication axis, and gap is equipped between felt lubrificated wheels and upper plate, are set in lubrication axis
Have grease channel, with the lubrication axis of felt lubrificated wheels socket place on the outside of be equipped with annular oil groove, annular oil groove leads to lubricating oil
Road is connected.
Preferably, the grease channel is connected with a pipe fitting, and pipe fitting internal pipeline is connected with grease channel.
Preferably, lubricate and be connected below axis by screw and lower roof plate, the top for lubricating axis is connected with upper plate clamping.
Preferably, the felt lubrificated wheels are engaged with a rack is connected.
Compared with prior art, the utility model has the advantages that：The utility model is close to the front end of rack and pinion engagement
Or rear end is installed, make felt lubrication wheel and rack engagement；Lubricating oil is led to by pipe fitting into the lubricating oil in lubrication axis
In road, by being oozed out from annular oil groove, lubricating oil impregnates felt lubrificated wheels, and the engagement of wheel and rack is lubricated by felt, real
Now tooth surface of rack is uniformly lubricated；The utility model is simple in structure, and cost is low, and reliability is high, and lubricating efficiency is high, can effectively carry
The service life of high rack-and-pinion.
Brief description of the drawings：
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the utility model and rack mesh schematic representation.
Fig. 3 is the sectional view along A-A of Fig. 2.
In figure, 1, stent, 2, upper plate, 3, lower roof plate, 4, lubrication axis, 5, felt lubrificated wheels, 6, grease channel, 7, ring
Shape oil groove, 8, pipe fitting, 9, rack, 10, screw.
Embodiment：
In order to clarify the technical characteristics of the invention, below by embodiment, and its attached drawing is combined, to this reality
It is described in detail with new.
As shown in Figs. 1-3, a kind of rack pinion self-lubricating device, including stent 1, a C is equipped with the side of stent 1
Shape groove, the C-channel include the upper plate 2 and lower roof plate 3 being connected with stent 1, and a lubrication axis 4 passes through upper plate 2 and lower roof plate 3
And be connected with upper plate and lower roof plate 3, the felt lubrificated wheels 5 are set on lubrication axis 4, in felt lubrificated wheels 5 and upper plate 2
Between be equipped with gap, be equipped with grease channel 6 in lubrication axis 4, set on the outside of the lubrication axis 4 with 5 socket place of felt lubrificated wheels
There is annular oil groove 7, annular oil groove 7 is connected with grease channel 6.
The grease channel 6 is connected with a pipe fitting 8, and 8 internal pipeline of pipe fitting is connected with grease channel 6.Pipe connects
First 8 setting is lubricated easy to the utility model.
Lubricate the lower section of axis 4 to be connected by screw 10 and lower roof plate 3, the top for lubricating axis 4 is connected with the clamping of upper plate 2.Even
It is reliable to connect mode, and installation, dismounting are all easier.
The felt lubrificated wheels 5 are engaged with a rack 9 to be connected.
In use, lubricating oil flows through pipe fitting 8 by oil inlet pipe enters lubrication axis 4, the grease channel being equipped with axis 4 is lubricated
6, and the oil groove for being located at 4 surface of lubrication axis being connected with grease channel 6, lubricating oil is smoothly immersed in felt lubrificated wheels 5
On, by engaging for felt lubrificated wheels 5 and rack, lubricating oil is uniformly lubricated on the flank of tooth of rack, in rack-and-pinion
Engagement process in, lubricating oil at the same time also lubricates gear, thus reduces the abrasion of rack-and-pinion, improves gear
The service life of rack.
Above-mentioned embodiment cannot function as the limitation to scope of protection of the utility model, for the skill of the art
For art personnel, any alternate modification or conversion made to the utility model embodiment all fall within the guarantor of the utility model
In the range of shield.
Part is not described in detail for the utility model, is the known technology of those skilled in the art of the present technique.
