Description

Harmonic wave speed reducing machine with lubrication keeper

Technical field

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

Background technology

Harmonic wave speed reducing machine is a kind of deceleration device with high speed reducing ratio, a rigid internal gear is consisted predominantly of in known structure configuration, the one flexible external tooth cup in rigid internal gear, and one be rotatably arranged in baud generator in flexible external tooth cup, after baud generator is assembled in flexible external tooth cup, flexible external tooth cup can become ovalisation by outer peripheral edge institute's ejection of baud generator, whereby, when baud generator is started to rotate by the driving of power source, it can be fully engaged against at the major axis of baud generator between rigid internal gear and flexible external tooth cup, and can be completely disengaged from the short axle of baud generator, due to there is the difference of the number of teeth between rigid internal gear and flexible external tooth cup, so when baud generator is persistently rotated, this number of teeth difference just can reach the effect of high speed reducing ratio, the output of high torque can so be produced.

In order to reach the effect in extension life-span and reduction abrasion, there is different Lubrication Designs in terms of located by prior art, such as US7, 905, 326 Patent Cases, which are mainly, allows lubricating oil to be injected via the oil passage of rigid internal gear in the oil supplying hole of flexible external tooth cup, baud generator is allowed to obtain lubricant effect, but it is due to that flexible external tooth cup can be constantly be generated elastic deformation in action process, so being easy to the phenomenon of generation stress concentration in the position of oil supplying hole and causing the structural failure of flexible external tooth cup, and because lubricating oil can be toward the flowing of lower position, relative internal bearings and shaft coupling just can not effectively lubricatings, so that the service life reduction of reductor.

The content of the invention

It is an object of the invention to provide a kind of harmonic wave speed reducing machine for having and lubricating keeper, it can be sufficiently carried out lubrication, use the effect for reaching extension life-span and reduction abrasion.

In order to reach above-mentioned purpose, solution of the invention is：

A kind of harmonic wave speed reducing machine with lubrication keeper, including：One rigid gear, a flexible gear and a baud generator, the rigid gear are provided with internal tooth, and the flexible gear is provided with the external tooth of the relative internal tooth, and local internal tooth is intermeshed with external tooth, and the flexible gear is provided with a holding part；The baud generator is in the holding part of the flexible gear, and the baud generator includes a bearing, a cam, an Europe single coupling shaft device and lubrication keeper；The bearing holder (housing, cover) is located at the cam, the Europe single coupling shaft device includes a driving member and a terminal pad, the terminal pad is between the cam and driving member, and the terminal pad, driving member and cam are connected by the structure of male-female engagement, the lubrication keeper is arranged between the inner edge surface of the holding part of the outer edge surface of the driving member and flexible gear, the lubrication keeper has lip, the lip has first end and the second end, the first end is fixed on the outer edge surface, second end contacts at the inner edge surface, the outer end of the bearing is provided with an oil seal, it is the lubricating place that an offer oil refill to be provided between the lubrication keeper and the oil seal, the lubricating place is installed with the bearing, cam and Europe single coupling shaft device.

Preferably, the driving member has a drive plate and the projection being connected with the drive plate, the drive plate has an assembled portion and two first recesses；The terminal pad has one to wear the first perforation therein for the projection, and two first projections and the second projection are set respectively in the terminal pad both ends of the surface, two first projections and the second projection are arranged in both ends of the surface with 180 degree respectively, and first projection and the second projection interlock 90 degree of arrangements；The cam has one to wear the second perforation therein and two second recesses for the projection；Two second recesses are embedded wherein for first projection, and first projection can slide in the second recess；Two first recesses are embedded wherein for second projection, and second projection can slide in the first recess.
