Description
Technical field
The present invention relates to technical field of mechanical transmission, more particularly to a kind of centrifugal friction damper.
Background technology
It is passed through in traditional machine driving application frequently with hydraulic damper, but hydraulic damper has damping force by temperature shadow
It rings greatly, and there are the shortcomings of oil leak.
Invention content
Goal of the invention：It is mechanically operated by the high speed impact brought in the process in order to prevent, inhibits vibration, plays damping shock absorption
Effect, the present invention propose a kind of centrifugal friction damper.
Technical solution：
A kind of centrifugal friction damper, is made of brake hoop and centrifugal rotor two parts, centrifugal rotor include armature spindle,
Centrifugal-block stent, centrifugal-block, shaft gear is equipped on the armature spindle, and the brake hoop includes retainer ring and is bonded in retainer ring
The nitrile rubber of bore area, centrifugal rotor are assemblied in by the bearing of armature spindle one end in the bearing chamber of housing, and armature spindle is another
The bearing of one end is assemblied in the bearing chamber of rear end cap, and brake hoop is fixed on by bolt on housing cavity.
Further, also comprising planet gear speeder, which increases the centrifugal friction damper for two-stage planet
Speed, first order input shaft are connect with rocking arm, and input shaft is supported and fixed on drive end bearing bracket, and pressure passes through axis there are three axis pin on input shaft
Installation is held there are three planetary gear, three planetary gears simultaneously with ring gear and planet carrier outer ring tooth engagement, three planetary gears, internal tooths
Circle forms first order planetary gear speedup with planet carrier outer ring tooth；Pressure is installed there are three axis pin by bearing on the planet carrier of the second level
There are three planetary gear, three planetary gears engage simultaneously with ring gear and shaft gear, three planetary gears, ring gear and shaft gear shape
Into second level planetary gear speedup.
Further, bushing is pressed on rocking arm.
Advantageous effects：

Specific embodiment
The present invention is described further below in conjunction with the accompanying drawings：
The centrifugal friction damper, it is characterised in that：The damper includes two-stage planet speedup, and the support of input shaft 10 is solid
It is scheduled on drive end bearing bracket 8, by bearing installation, there are three planetary gears 6 there are three axis pin 7 for pressure on input shaft 10, and three planetary gears 6 are together
When with 11 outer ring tooth engagement of ring gear 5 and planet carrier, three planetary gears 6,11 outer ring tooth of ring gear 5 and planet carrier form first
Grade planetary gear speedup；By bearing installation, there are three planetary gear 13, three planetary gears there are three axis pin 12 for pressure on planet carrier 11
13 engage simultaneously with ring gear 5 and shaft gear 14, and three planetary gears 13, ring gear 5 and shaft gear 14 form second level planet
Gear up.
Damper is made of brake hoop and centrifugal rotor two parts, and centrifugal rotor includes armature spindle 15, centrifugal-block stent
Shaft gear 14 is installed, centrifugal rotor is assemblied in by the bearing of 15 one end of armature spindle on the 16th, centrifugal-block 17, wherein armature spindle 15
In the bearing chamber of housing 4, the bearing of 15 other end of armature spindle is assemblied in the bearing chamber of rear end cap 1, and the brake hoop includes solid
Determine ring 3 and be bonded in the rubber 2 of fixed ring inner surface, brake hoop is fixed on by bolt on housing cavity.
The present invention operation principle be:When rotating rocking arm 9, input speed realizes speedup by two-stage planet group
And armature spindle 15 is transferred to, armature spindle drives centrifugal-block stent 16 to rotate, and makes to be assemblied in the centrifugal-block among centrifugal-block stent 16
17 because centrifugal force effect is thrown away, and the centrifugal-block 17 thrown away will generate with 2 face of brake hoop rubber and contact and rub, and then generate
Frictional resistance, generated frictional resistance act on and damping are generated on rocking arm 9 after the amplification of two-stage planet group.
