Slot 23.It is understood that one end on the first dustproof groove 23 far from centrifugal chamber 7 is enclosed construction.
Authorization Notice No. is that the patent document of CN205956252U proposes a kind of be used for the output of sanitation cart assistant engine
The centrifugal clutch at end, in use, get rid of be easy to appear when the friction plate 31 on block 3 is connect with outer ring 22 slippage,
The case where skidding, so that the work that the torsional forces of transmitting becomes smaller suddenly and is unable to satisfy the workpiece connecting with the second rotor needs
It asks.Inventor has found that its producing cause is that occur lubricating oil (from bearing assembly 4) between friction plate 31 and outer ring 22, i.e.,
Make to devise above-mentioned the first separator 5 and the first dustproof groove 23 engaged therewith, is still that can not solve the problems, such as this.To prevent axis
Lubricating oil on bearing assembly 4 enters centrifugal chamber, and inventor passes through long-term experiment, proposes following structures.
With reference to Fig. 3, an oily flute 24 is offered on the second mounting portion 12, which is connected on the first dustproof groove 23
One end far from centrifugal chamber 7.The oil flute 24 is provided on third mounting portion 21 for cyclic structure, and 24 edge of oil flute
Radially outward extension radial dimension is greater than the maximum radial dimension of the first dustproof groove 23 radially.The oil flute 24 is the application's
Clutch is in use, the lubricating oil sputtered from bearing assembly 4 can be equipped with, and it is in the course of rotation, into oil
The lubricating oil of flute 24 is because of centrifugal force without flowing into centrifugal chamber 7 through lesser first dustproof groove 23 of radial dimension.It is excellent
Selection of land, the size value of oily flute 24 radially are greater than the maximum radial dimension value (single side size) of the first dustproof groove 23 radially
1mm or more.It is understood that in other embodiments, be configurable to effect it is poor no more than 1mm.It is understood that
, the first separator 5 is clearance fit to prevent it from interfering the rotation of the second rotor 2 with third mounting portion 21, first every
In the case that off member 5 and third mounting portion 21 are clearance fit, the oil on bearing assembly 4 can enter in centrifugal chamber 7.It can manage
It solves, one end on oily flute 24 far from centrifugal chamber 7 is enclosed construction.Wherein, oily flute 24 has one to connect the
Centrifugal force when the limiting unit 24A of one dustproof groove 23, the limiting unit 24A cooperation rotation makes the oil in oily flute 24 will not be along axis
To inflow centrifugal chamber 7.
In the embodiment of the application, with reference to Fig. 4, the second separator 6 is supported on bearing assembly 4 far from the first separator
