Description

Lubrication system towards tooth machine drive mechanism

This utility model is about a kind of lubrication system towards tooth machine drive mechanism, especially the axle bed peripheral hardware sleeve that refers to a kind of drive mechanism, and form between sleeve and axle bed and hold oily space for storing lubricating oil, set the lid of tool driving fit cover again on the sleeve, and the eccentric shaft of drive mechanism and actuating strut pass the driving fit cover and stretch in the lubricating oil, cooperate actuation and produce the lubricating oil effect of drawing, and form the innovation structure of good lubrication effect.

See also shown in Figure 1, drive mechanism towards the tooth machine commonly used is to be provided with an axle bed 12 in support 11 bottom surfaces, axle bed 12 is provided with a fixed axostyle 13, wear a gear 15 that is connected with eccentric shaft 14 on the axostylus axostyle 13, travelling gear 17 interlocks of its middle gear 15 sides and a drive motor 16, eccentric shaft 14 then cooperates a lining 18 to be arranged in an actuating strut 19 1 ends, and the other end of actuating strut 19 then is mounted on and can moves back and forth on the pumping water device 21 and do not deviate from pumping water device 21.

See also Fig. 1, shown in Figure 2, when drive motor 16 moves with travelling gear 17 driven gears 15, actuating strut 19 1 ends are placed restrictions on pumping water device 21 because eccentric shaft 14 is rotatably assorted, causative action bar 19 rotates and reciprocal linearly operating with eccentric shaft 14, make actuating strut 19 on pumping water device 21, form the effect that back and forth pushes, release with the water pressurization that will enter pumping water device 21, use for user and constitute powerful water column.

The design of above drive mechanism is in order to the water column pressurization to be provided, therefore the action of eccentric shaft 14 is quite fast, constitute the powerful water column that continues in the hope of driving actuating strut 19 fast, therefore the friction of 13 of eccentric shaft 14 and axostylus axostyles, lining 18 and eccentric shaft 14 frictions, the friction of lining 18 and actuating strut 19 ends, all quite violent, the formed frictional dissipation of face is just quite obvious so contact with each other, when as a result actuating strut 19 pushes water column, because of the spacing military order actuating strut 19 generation collisions that frictional dissipation between member produced, rock and cause the action force deficiency, and the action force deficiency is just not enough towards the water outlet hydraulic pressure of tooth machine, from reaching towards the tooth effect, moreover actuating strut 19 Fast Collision situations, be easy to cause component failures, therefore commonly used higher towards tooth machine operational failure rate, do not meet functional need.

And or have the part maker can be after the actuating strut 19 of drive mechanism is finished with eccentric shaft 14 assemblings, coating lubricating oil on the surface, but the lubricating oil of this kind cloth of coating-type only has lubricant effect to partial position, limited for whole operating bar 19 with 14 effects of eccentric shaft, moreover the lubricating oil that is coated on the surface can dry up with increasing service time, so nonideal lubricated enforcement state is so still have the necessity that is improved.

In view of this, use always towards tooth machine drive mechanism because of there not being practical lubrication, and produce structural loss and use effect unclear, so this utility model provides a kind of lubrication system towards tooth machine drive mechanism, it is to be provided with sleeve outside the axle bed of drive mechanism, and make between sleeve and axle bed to form and hold oily space for storing lubricating oil, and on sleeve, set a lid, and the driving fit cover is arranged on the lid, make the actuating strut of drive mechanism pass the driving fit cover and contact, reach the good lubrication effect according to this with lubricating oil with eccentric shaft.

The purpose of this utility model provides a kind of lubrication system towards tooth machine drive mechanism.

The purpose of this utility model is achieved in that a kind of lubrication system towards tooth machine drive mechanism, it is characterized in that: this structure is that an axle bed periphery that is installed in the support bottom surface is provided with a sleeve, be formed with between sleeve and axle bed and hold oily space, be equipped with a lid again on the sleeve, lid is provided with soft and the elastic driving fit cover of tool, drive mechanism passes the driving fit cover according to this, contacts with holding oily spatial lubricating oil, can reach lubricant effect when making the actuating mechanism action.Wherein sleeve surface can be made and establish some blockings hole, and top surface system is provided with some blocking salient points, utilizes the blocking hole of sleeve surface to combine with the blocking salient point of lid to form blocking according to this.

In sum, this utility model utilizes the setting of sleeve and lid, adds that actuating strut one end and eccentric shaft stretch in the driving fit cover, contact with the lubricating oil that holds in the oily space between sleeve, axle bed, thus constitute good lubricating effect, with the defective of solution common structure.

See also Fig. 3, shown in Figure 4, this utility model is towards the lubrication system of tooth machine drive mechanism, it is that axle bed 32 peripheries that are installed in support 31 bottom surfaces are provided with a

sleeve

33, and 32 of sleeve 33 and axle beds are formed with and hold oily space 34, and sleeve 33 surfaces can be made and are provided with some blockings hole 35; Be equipped with a lid 36 again on the sleeve 33, these lid 36 surface systems are provided with some blocking salient points 37 and form blocking with the blocking hole 35 with sleeve 33 surfaces, so that lid 36 is positioned sleeve 33 tops, and lid 36 is provided with soft and tool elasticity driving fit cover 38, and the top of driving fit cover 38 offers perforation 39.

In view of the above the integral body of eccentric shaft 41 and gear 42 can be on eccentric shaft 41 a sheathed lining 43, and be located in actuating strut 44 1 ends, and eccentric shaft 41, actuating strut 44 in conjunction with after pass driving fit cover 38 again perforation 39, eccentric shaft 41 and actuating strut 44 can be dipped in the lubricating oil.

In addition, travelling gear 46 interlocks of gear 42 and drive motor 45, and actuating strut 44 other end groups are located on the pumping water device 47, because of duplicating with common structure and not giving unnecessary details for the former not polylogia in feature of the present utility model place.

See also shown in Figure 5, when gear 42 is subjected to power and rotates, the eccentric shaft 41 of gear 42 belows also rotates, and because the design of the off-centre of eccentric shaft 41 makes it have the shift reciprocately effect in rotating, pressurization makes it pump formation to suppress and help to use towards tooth to water so can drive that actuating strut 44 moves back and forth.

And in the use, eccentric shaft 41 and actuating strut 44 stretch into the part of driving fit cover 38, has quite high velocity of rotation, so the opposed lubricating oil that holds in the oily space 34 that is stored in produces high speed swinging, and make lubricating oil be drawn onto axostylus axostyle 48 surfaces on the axle bed 32 by this with rotation, eccentric shaft 41 surfaces, the surface of lining 43 surfaces and actuating strut 44 1 ends, in other words each member contact surface of drive mechanism is all obtained good lubrication, so can reduce the friction loss between member, make member be difficult for colliding relatively, increase service life to reach because of gap generation when moving to each other, reduce the effect of fault rate.

It is more certain that certain combination between each member can make actuating strut 44 actions according to this again, and the competent pressure of application of force current makes current output form powerful water column relatively, washes tooth to help user, and the demand of realistic use.

In addition, because driving fit cover 38 set on the lid 36 is soft flexible, so when operating bar 44 and eccentric shaft 41 pass driving fit when overlapping 38, driving fit cover 38 can tightly be restrainted in actuating strut 44 1 end surfaces, and during molar behavior, driving fit cover 38 is swing thereupon, so eccentric shaft 41 can be swung smoothly with actuating strut 44, and driving fit cover 38 has and prevents to hold oily space 24 interior lubricating oil and ooze out effect.
