Connected by block rubber, the axle center of the metal inner ring, which is provided with, is used for the positioning hole that power transmission shaft passes through, the side of the metal inner ring
Circular array has some limit chambers on wall, is provided with alignment pin in the limit chamber, on the two side of the block rubber formed with
Some locating parts in tooth form.
Circular array has four limit chambers in the side wall of the metal inner ring, and the alignment pin is arranged at the limit chamber
It is interior.
The alignment pin is the middle thin thick cone limited post in both ends, both ends limited location boss.
Formed with passage between the adjacent limit chamber.
The curved through hole of passage, formed with projection on the inwall of the passage.
The metal inner ring is provided with four connecting holes for being used to be connected with power transmission shaft adpting flange.
The beneficial effects of the utility model are：
1. the utility model is connected by metal inner ring with the universal joint adpting flange on power transmission shaft, it is assemblied on automobile,
Rotated in vehicle operation with rotating speeds such as power transmission shafts, simple in construction, dependable performance is spacing compact, is assemblied in power transmission shaft adpting flange
On, transmission system twisting vibration can be effectively reduced, reduces noise, improves ride comfort；
2. the utility model limits the twist motion of torsional vibration damper by the locating part being arranged on block rubber.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is profile of the present utility model.
In figure, 1 metal outer ring, 2 metal inner rings, 3 block rubbers, 4 positioning holes, 5 limit chambers, 6 alignment pins, 7 passages, 71 is convex
Block, 8 locating parts, 9 connecting holes.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
Referring to Fig. 1-2.
The utility model discloses a kind of power transmission shaft torsional vibration damper, including metal outer ring 1, metal inner ring 2, the metal
Inner ring 2 is arranged at the inside of metal outer ring 1, and the metal inner ring 2 and metal outer ring 1 are coaxial, outside the metal inner ring 2 and metal
Connected between circle 1 by block rubber 3, the axle center of the metal inner ring 2, which is provided with, is used for the positioning hole 4 that power transmission shaft passes through, the gold
Belonging to circular array in the side wall of inner ring 2 has some limit chambers 5, and alignment pin 6 is provided with the limit chamber 5, the block rubber 3
Formed with some locating parts 8 in tooth form on two side, this case block rubber 3 by vulcanize respectively with the inwall of metal outer ring 1 with
And the outer wall connection of metal inner ring 2, the twist motion of torsional vibration damper is limited by the locating part 8 being arranged on block rubber 3, is led to
Cross metal inner ring 2 to be connected with the universal joint adpting flange on power transmission shaft, be assemblied on automobile, turn in vehicle operation with power transmission shaft etc.
Speed rotation, simple in construction, dependable performance is spacing compact, is assemblied on power transmission shaft adpting flange, can effectively reduce transmission system torsion
Rotational oscillation moves, and reduces noise, improves ride comfort.
Circular array has four limit chambers 5 in the side wall of the metal inner ring 2, and the alignment pin 6 is arranged at the limit
In the chamber 5 of position, it is fitted in by alignment pin 6 in the cavity of block rubber 3, limits the axial displacement of block rubber 3, there is provided service life.
The alignment pin 6 is the thick cone limited post in middle thin both ends, both ends limited location boss 61, forms axial limiting
Device, 1 axial over-travel of metal outer shroud can be limited, effectively prevent the ultralimit of block rubber 3 from deforming and pre-burst failure.
