Abstract
An elastic gear for diesel engine comprises a hub an a gear ring, which is characterized in that the hub and the gear ring are detachable, a machining groove is provided at the corresponding place of the outside of the hub and the inner side of the gear ring, the two apparatus construct a cavity, a rubber elastomer is filled in the cavity through the filling-hole of the gear ring to combine the hub and the gear ring. The utility model uses the rubber elastomer to decrease the stress concentration and absorb the vibration energy, which avoids that the air compressor crankshaft of diesel engine is generating repeated stress failure and reduces the vibration and noise of the diesel engine.
Description
Technical field
The utility model relates to the gear technique field, specifically relates to a kind of resislient gear that is used on the diesel engine.
Background technique
The general employing of the air compressor of existing high-horsepower diesel engine drawn together the gear transmission of plug formula, gear is monolithic construction, with the air compressor crank (see figure 2) that is rigidly connected, because the hole is inconsistent with angle tolerance size, the direction of axle, cause axially on each cross section contact stress inhomogeneous, the cross section of contact stress maximum stress under the effect of gear radial force is concentrated also maximum, makes the easy fatigue fracture of bent axle, and the load of this gear train assembly is impact load, can produce bigger vibration and noise.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of use for diesel engine resislient gear of avoiding diesel air press crankshaft fatigue fracture and can reducing diesel vibration and noise is provided.
The utility model use for diesel engine resislient gear includes wheel hub and gear ring, and its structural feature is that wheel hub and gear ring are split type, and promptly wheel hub and gear ring are two parts independently, and the two is bound up by rubber elastomer.
Use for diesel engine resislient gear as mentioned above, be that corresponding position in the wheel hub outside and gear ring inboard is processed with groove respectively, the two common formation cavity is perfused with rubber elastomer by the fill orifice that is located on the gear ring in cavity, wheel hub and gear ring are bound up.
Owing to adopt rubber elastomer to connect between the utility model wheel hub and the gear ring, and rubber modulus is very little and have a higher internal resistance, being hit property of gear tangentially, radially, during axial force, the power of all directions acts on the elastomer simultaneously, utilize rubber elastomer to reduce the concentrated and absorption vibrational energy of stress, thereby can avoid diesel air press crankshaft fatigue fracture and can reduce diesel vibration and noise.
Description of drawings
Fig. 1 is the structural representation after the installation of the present utility model;
Fig. 2 is existing diesel air press driving gear structural representation.
Embodiment
Embodiment illustrated in fig. 1, the utlity model has wheel hub 2 and gear ring 1, wheel hub 2 and gear ring (1) are split type, being wheel hub and gear ring is two parts independently, corresponding position in the inboard of the outside of wheel hub 2 and gear ring 1 is processed with groove respectively, and the two is common to constitute and connect cavity, is perfused with rubber elastomer 3 by the fill orifice 8 that is located on the gear ring 1 in cavity, utilize rubber elastomer 3 that wheel hub 2 and gear ring 1 are bound up, constitute resislient gear.During installation, wheel hub 2 rigidly fixes with 1: 5 hole of tapering axle interference fit with diesel engine air compressor crank 7 and is one, axle head is equipped with the lock washer 4 that has limited impression by gland nut 6, lock washer 4 is fixing with gear ring 1, location flat key 5 is housed between the limited impression of lock washer 4 and wheel hub 2 ends, the width of limited impression is the circumferential maximum flexibility variable of permission greater than the width of location flat key 5 greater than amount.
Claims (2)
1, a kind of use for diesel engine resislient gear includes wheel hub (2) and gear ring (1), it is characterized in that: wheel hub (2) and gear ring (1) are for split type, and the two is bound up by rubber elastomer (3).
2, use for diesel engine resislient gear according to claim 1, it is characterized in that being processed with groove respectively in wheel hub (2) outside and the inboard corresponding position of gear ring (1), the two common formation cavity, in cavity, be perfused with rubber elastomer (3), wheel hub (2) and gear ring (1) are bound up by the fill orifice (8) that is located on the gear ring (1).
