Be the most preferred embodiment of vibration damper of the present invention below, the details that provides this vibration damper by description and accompanying drawing to its structure.
As shown in Figure 1, parts (1) are that inner ring, parts (3) are flying wheels, and above-mentioned both can process with steel or cast iron materials, and parts (2) are rubber rings, and it is generally with vulcanite or soft rubber processing.The external cylindrical surface of inner ring (1) has the profile of concave arc shape, radius of arc R
1Be 542.05 millimeters, its body length is 110 millimeters, and maximum outside diameter is 138 millimeters.The inner cylindrical surface (1a) of inner ring (1) matches with the axle of engine free end, and this vibration damper is fastened on the outrigger shaft of engine free end by nut by means of the inner convex platform (1b) of inner ring (1).The axial length of flying wheel (3) is identical with inner ring (1), and inner cylindrical surface also is an arc, its radius of arc R
2It is 542.05 millimeters.But an end of flying wheel (3) is the bigger disk of diameter (3a), its objective is in order to make it have certain quality.This flying wheel (3) is gone back the double as belt pulley and is used.So processed three v belt grooves, so that drive the annex of engine free end.
As a kind of conversion, the concave arc shape shown in the accompanying drawing 1 can be replaced by the concave-concave taper, and the angle of its conical surface and axis is 4.1 °.The concave-concave taper is identical with the function of concave arc shape, but the former is easy to process.
Accompanying drawing 2 is straight shape embodiments of vibration damper of the present invention, and wherein the axial inner cylindrical surface of the axial external cylindrical surface of inner ring (1) and flying wheel (3) is straight.Have two road ring-type zigzag fashion grooves (1c) on the external cylindrical surface of inner ring (1), the wide of this groove (1c) is 4 millimeters, and what be pressed into end at rubber ring (2) is 0.5～0.6 millimeter deeply.This structure has overcome the axial float problem effectively.An outer protruding circular column (1a) is arranged on the inner ring (1), and circle has keyway (1b) in it, so that this vibration damper is installed on the outrigger shaft of engine free end.Two v belt grooves that are used to drive other annex have only been processed on the flying wheel (3).
Accompanying drawing 3 is the embodiments that are used to make above-mentioned vibration damper critical process.
For the vibration damper of different structure, the structure of press-loading device also is not quite similar.Among the figure, parts (4) are top dies, and parts (5) are dip molds, and parts (8) are interior guide pin bushings, and parts (9) are outer bushs, and these parts are generally all processed with steel.Be welded with four uniform weeks of lug (10) that have bolt (12) on the above-mentioned dip mold (5).Corresponding, also be welded with the lug (11) of four (14) with holes on the above-mentioned outer bush (9).The manufacturing process that above-mentioned rubber ring (2) is pressed between inner ring (1) and the flying wheel (3) is as follows:
Earlier the inner ring (1) that processes is enclosed within on the apotting spindle (5a) of dip mold (5), the flying wheel that processes (3) is placed on the dip mold (5), and by positioning spigot (5b) location, again interior guide pin bushing (8) is enclosed within on the apotting spindle (5a) of dip mold (5), outer bush (9) is placed on the flying wheel (3), and the external cylindrical surface of flying wheel (3) plays the role of positioning to the inner cylindrical surface (9a) of outer bush (9).Should note making bolt (12) to be positioned at the hole (14) of lug (11) this moment.Then, the nut (7) on tight a bolt (6) is pressed on interior guide pin bushing (8), inner ring (1) on the dip mold (5), and the nut (13) on tight a bolt (12) is pressed on outer bush (9), flying wheel (3) on the dip mold (5).At last, on the interior outside of rubber ring (2) behind the uniformly lubricated Bond of coating, put into the annular groove between guide pin bushing (8) and the outer bush (9), rubber ring (2) be pressed into position shown in the accompanying drawing 3 with the gland (4b) on the top die (4), after the demoulding the vibration damper product.
Above-mentioned combined shock absorber and gluing pressure craft thereof have following advantage:
This damper structure is simple, the good damping result of shock absorber, and also the double belt pulley of doing is used. Therefore, can be widely used in vehicular engine. Rubber ring be pressed into simple process, and also not easily broken in using, reliability and the sense of security improve. In production in enormous quantities, carry out easily semi-automatic or full-automatic production. For the shock absorber that two road zigzag grooves are arranged, in 2 seconds, the rotating speed of engine is accelerated to 2800 rev/mins from 600 rev/mins, per hour carry out 6 times, done altogether 500 hours 3000 times thermal shock test, this shock absorber is excellent, does not also produce axial float.
