Description

Harmonic wave speed reducing machine with lubrication holder

Technical field

The present invention is related with harmonic wave speed reducing machine, particularly relates to a harmonic wave speed reducing machine for advising lubrication holder.

Background technique

Harmonic wave speed reducing machine is a kind of deceleration device with high reduction ratio, mainly includes one in known structure configuration Rigid internal gear, a flexible external tooth cup being set in rigid internal gear and one are rotatably arranged in the wave in flexible external tooth cup Generator, after baud generator is assembled in flexible external tooth cup, flexible external tooth cup can by outer peripheral edge institute's ejection of baud generator and Become ellipse, whereby, when baud generator is started turning by the driving of power source, rigid internal gear and flexible external tooth cup Between can be fully engaged against at the long axis of baud generator, and can be completely disengaged at the short axle of baud generator, due in rigidity There is the difference of the number of teeth between ring gear and flexible external tooth cup, so this number of teeth difference just can reach when baud generator persistently rotates To the effect of high reduction ratio, the output of high torque so can produce.

In order to achieve the effect that extend the service life and reduce abrasion, there is different Lubrication Designs, example in terms of located by prior art If US7,905,326 Patent Case is mainly to allow lubricating oil via the oil supplying hole of the flexible external tooth cup of oil passage injection of rigid internal gear It is interior, allow baud generator to obtain lubricant effect, but since flexible external tooth cup can be constantly be generated flexible deformation in action process, So being easy to concentrate and cause the structural failure of flexible external tooth cup there is a phenomenon where stress in the position of oil supplying hole, and because profit Lubricating oil can be flowed toward lower position, opposite internal bearings and shaft coupling just can not effectively lubricating so that the service life of speed reducer drops It is low.

Summary of the invention

The purpose of the present invention is to provide a kind of harmonic wave speed reducing machines with lubrication holder, can be sufficiently carried out profit It is sliding, use to achieve the effect that extend the service life and reduce wearing away.

In order to achieve the above objectives, solution of the invention is:

A kind of harmonic wave speed reducing machine with lubrication holder a, comprising: rigid gear, a flexible gear and a wave generate Device, the rigid gear are equipped with internal tooth, which is equipped with the external tooth of the opposite internal tooth, and local internal tooth and external tooth are intermeshed, The flexible gear is equipped with a holding part；The baud generator is set in the holding part of the flexible gear, which includes an axis Hold, a cam, an Europe single coupling shaft device and lubrication holder；The bearing holder (housing, cover) is set to the cam, which includes a transmission Part and a terminal pad, the terminal pad is between the cam and driving member, and the terminal pad, driving member and cam are matched by bumps The structure of conjunction connects, the lubrication holder be set to the outer edge surface of the driving member and the holding part of flexible gear inner edge surface it Between, which has lip, which has first end and second end, which is fixed on the outer edge surface, and second End contacts at the inner edge surface, and it is to form one between the lubrication holder and the oil seal that the outer end of the bearing, which is equipped with an oil seal, The lubricating place of oil refill is provided, which is installed with the bearing, cam and Europe single coupling shaft device.

Preferably, the pillar that the driving member has a drive plate and connect with the drive plate, which has an assembling Portion and two first recess portions；The terminal pad has one to wear the first perforation therein for the pillar, and in the terminal pad both ends of the surface point Not She Zhi two first convex blocks and the second convex block, two first convex blocks and the second convex block be arranged in both ends of the surface respectively with 180 degree, and should First convex block and the second convex block interlock 90 degree of arrangements；The cam have one for the pillar wear it is therein second perforation, Ji Liang Two recess portions；Two second recess portions are embedded wherein for first convex block, and first convex block can slide in the second recess portion；Two this is first recessed Portion is embedded wherein for second convex block, and second convex block can slide in the first recess portion.

Preferably, the lubrication holder is additionally provided with a leakage barriers, which coats the bottom surface of the drive plate.
