Description
Technical field
The utility model relates to speed changer field, particularly relates to a kind of auxiliary support apparatus for speed changer fatigue life test.
Background technique
The transmission assembly of existing truck, particularly multi-speed transmission assembly, because of its quality large (500Kg left and right), only rely on clutch housing to support separately speed changer load excessive, so when truck arrangement, the general auxiliary support structure (mostly being two point-supported girder structures) that is all designed with speed changer, to alleviate the load of speed changer that clutch housing is supported, to prevent clutch housing distortion and damaged by excessive stresses.While carrying out speed changer laboratory test, particularly when speed changer fatigue life test, because of the arrangement space of test stand limited, and the size of speed changer is larger, auxiliary support structure (two point-supported girder structures) cannot be designed to arrangement time, and the load of fatigue life test is larger, as easily causing the bearing of speed changer, the supplemental support without speed changer is out of shape, the phenomenons such as speed changer vibration, thereby cause speed changer earlier period damage, so, be necessary to design a simple and effective auxiliary support mechanism, improve speed changer installation strength, elimination is inaccurate because of the not enough test result causing of installation strength.
Generally, carry out the indoor fatigue life test of speed changer auxiliary support structure is not set, existing auxiliary support structure has following two kinds: 1. adopt jack directly withstanding speed changer rear end, play the effect that necessarily alleviates speed changer front end supported weight, but because jack has only played the effect that holds up speed changer, for speed changer upwards and left and right directions without effect of contraction, the vibration producing while therefore speed changer being subject to large load High Rotation Speed does not have any effect; 2. adopt the direct fixed transmission of steelframe rear end, the steelframe firm formula fixing with floor slab is connected, and clearly, which is because of nothing buffering, in steelframe and speed changer compaction process, easily produce over-stress, and the vibration of operation process is because will causing joint to produce excessive instantaneous stress without absorbing mechanism.Therefore these two kinds of modes are all imperfection, insecure.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of auxiliary support apparatus for speed changer fatigue life test is provided, in the time carrying out speed changer fatigue life test, it can carry out supplemental support to speed changer rear end, and absorb speed changer produce vibration, improve speed changer installation strength, increase the reliability of test result.
The purpose of this utility model is achieved in that
A kind of auxiliary support apparatus for speed changer fatigue life test, auxiliary support apparatus comprises connecting plate, rubber buffer, support, described support comprises top board, base plate and biside plate, top board, base plate is parallel to each other, biside plate is welded on respectively top board, the both sides of base plate, formation is the frame structure of isosceles trapezoid, the base plate of support is provided with the trimming bolt for adjusting pole height, described connecting plate is fixed on support top by a connecting bolt, the two ends of described connecting bolt are connected to connecting plate, rack plate middle part, described rubber buffer is positioned at connecting plate, between support, connecting bolt runs through rubber buffer, and be positioned on the shaft axis of rubber buffer, connecting plate is provided with two strip through-holes for bolt fixed transmission, two strip through-hole symmetries are positioned at the both sides of connecting bolt.
The outer circumferential face indention of described rubber buffer.
The quantity of described trimming bolt is three, and wherein two trimming bolts are positioned at the two ends of support base plate, and another trimming bolt is positioned at the centre of support base plate.
The thickness of described rubber buffer is 20mm～100mm.
The length of described strip through-hole is 100 mm～300mm, and width is 10 mm～50mm.
Owing to having adopted such scheme, support is the isosceles trapezoid frame structure being welded and fixed, and intensity is high, not yielding, has good support effect, can reduce again installing space.Connecting plate is fixed on support top by a connecting bolt, the two ends of connecting bolt are connected to connecting plate, rack plate middle part, rubber buffer is between connecting plate, support, and connecting bolt runs through rubber buffer, and is positioned on the shaft axis of rubber buffer.Therefore; connecting plate can produce swing when stressed; suffered power is passed to rubber buffer; rubber buffer can be accepted the pressure that all directions are subject to; thereby absorb the vibration that speed changer produces; rubber buffer had both worked to support speed changer weight, can in the time that case of transmission is subject to excessive generation instantaneous stress because of vibration, play again buffer protection function.Connecting plate is provided with two strip through-holes for bolt fixed transmission, two strip through-hole symmetries are positioned at the both sides of connecting bolt, can fix the speed changer of all size size, than general manhole, the using scope of strip through-hole is wider, adapts to as far as possible the supplemental support hole of most speed changers, and connecting plate and speed changer are fixed as one, to the generation of vibration constraint of speed changer all directions, prevent its bearing distortion.The trimming bolt that the base plate of support is provided with, can adjusting pole height, ensures that base plate is positioned on horizontal plane, and the installation question causing to adapt to ground injustice, makes connecting plate can firmly connect speed changer.In the time carrying out speed changer fatigue life test, this auxiliary support apparatus can carry out supplemental support to speed changer rear end, and absorbs the vibration that speed changer produces, and improves speed changer installation strength, increases the reliability of test result.
The outer circumferential face indention of rubber buffer, makes rubber buffer in the time of pressurized, be difficult for occurring excessive deformation, the working life of improving rubber buffer.The quantity of trimming bolt is three, wherein two trimming bolts are positioned at the two ends of support base plate, another trimming bolt is positioned at the centre of support base plate, with respect to 2 supports, its join strength is higher, the thickness of described rubber buffer is 20mm～100mm, makes rubber buffer amount of deformation moderate, absorbs the better effects if of vibration.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
