Abstract
The invention relates to an aluminum foil adjustable pad used for a helicopter transmission system. The size of an aluminum foil pad body and the size of an installation surface of a cartridge receiver are the same, the aluminum foil pad body is divided into two parts, a groove is formed in a position of a fastening bolt, and the opening direction of the groove is toward the interior of the cartridge receiver. The thickness of the aluminum adjustable foil pad are various. By means of the aluminum foil adjustable pad used for the helicopter transmission system, the structure of the aluminum foil adjustable pad which is used by a previous helicopter transmission system is changed from an integral type to a split type, when trace and backlash of a gear are adjusted, the cartridge receiver does not need to be dismantled, the risks of collision and entering of redundancy in the dismantling process are avoided effectively, the requirements of assembling and area of repairing spot are reduced, and plenty of space, labor, material resources and time are saved.
Description
Technical field
The present invention relates to a kind of aluminium foil adjusting pad, the aluminium foil adjusting pad that especially a kind of Helicopter Transmission System is used.
Background technology
Helicopter Transmission System and rotor, driving engine are called as three large dynamic components of helicopter, belong to high-tech product, and Helicopter Transmission System is mainly to rely on gear transmission moment of torsion and load.And the impression of gear and backlash are the leading indicators of gear transmission power, moment of torsion, noise, vibration etc., when the impression of gear and backlash reach appropriate value, gear transmission just can reach the situation of its maximum power and minimal noise, be gear-driven ideal state, so the adjustment of gear impression and backlash belong to gordian technique.In the design process of present Helicopter Transmission System, due to factors such as space and flight safety, weight, sometimes the engagement situation of gear is closely bound up with the assembly relation of casing, be impression and the backlash situation that the relative position of casing affects gear, if need to adjust impression and the backlash of gear, need to adjust by the aluminium foil adjusting pad between casing.Aluminium foil adjusting pad between casing at present all Helicopter Transmission System is shown in Figure 1, go out the aluminium foil adjusting pad of the enclosed shape of respective shapes according to the profile design of casing, hold-down bolt Position Design at casing is through hole, the aluminium foil adjusting pad is configured to different thickness, to adapt to the needs of adjusting impression and backlash.When the Helicopter Transmission System transmission gear in assembling, in repair procedures, the assembly crewman is when adjusting impression and backlash, need to dismantle casing, take out former aluminium foil adjusting pad, put into new former aluminium foil adjusting pad, bolt is reinstalled fixing, if impression and backlash are when also out of reach requires, also to repeat above step, until impression and backlash also reach requirement.Because the casing volume of Helicopter Transmission System is larger, the weight maximum can reach 100KG, each dismounting and installation need a large amount of man power and materials, and Helicopter Transmission System belongs to high, refined, peak products, require very high to the dimensional accuracy of product, roughness of surface etc., casing has to collide with in each unloading process and enters equivalent risk with superfluity, has reduced the reliability of service of Helicopter Transmission System; The assembling and the adjustment time that have simultaneously also increased Helicopter Transmission System, and assembling, repairing site space are had strict requirement to satisfy the dismounting repeatedly of casing.
Summary of the invention
The purpose of this invention is to provide the aluminium foil adjusting pad that a kind of novel Helicopter Transmission System is used, can realize realizing the adjustment of gear impression and backlash within not needing strict site space, and a large amount of manpower and materials and assembling and adjustment time of actv. saving.
Concrete technical scheme of the present invention is, the aluminium foil adjusting pad that Helicopter Transmission System is used comprises the aluminum foil pad body, aluminum foil pad body and casing attachment face measure-alike, described aluminum foil pad body is divided into two parts, position at binding bolt is provided with groove, and the opening direction of described groove is the inside of casing.The thickness of described aluminium foil adjusting pad is a plurality of of different size.
Cut-off rule or its extended line of two parts of described aluminum foil pad body overlap, and can through the center-point of aluminum foil pad body, maybe can make the measure-alike of two-part aluminum foil pad body.
The present invention changes Split type structure by the aluminium foil adjusting pad that original Helicopter Transmission System is used into by integral body, in the install and adjust process of Helicopter Transmission System, do not need the binding bolt of casing is disassembled, the assembler only needs bolt is unclamped, casing is lifted slightly, to need not aluminium foil adjusting pad appropriate section is packed into from a side, then from opposite side, the aluminium foil adjusting pad of another part be packed into, can complete the adjustment of aluminium foil adjusting pad thickness.The present invention is not because need to dismantle casing, actv. has been avoided having in unloading process colliding with and has been entered equivalent risk with superfluity, and reduced assembling, repaired the requirement of site space, a large amount of spaces and human and material resources have been saved, simultaneously, the aluminium foil adjusting pad of changing different-thickness is very convenient, can realize the optimum regime that gear meshes by fast speed, has saved a large amount of assemblings and adjustment time.
Description of drawings
Fig. 1 is the structural representation of existing aluminium foil adjusting pad:
Fig. 2 is the structural representation of aluminium foil adjusting pad of the present invention.
The specific embodiment
As shown in Figure 2, the aluminium foil adjusting pad that Helicopter Transmission System is used comprises aluminum foil pad body 1, and aluminum foil pad body 1 is measure-alike with the casing attachment face, and described aluminum foil pad body 1 is divided into two parts, be provided with groove 2 in the position of binding bolt, the opening direction of described groove 2 is the inside of casing.The thickness of described aluminium foil adjusting pad is a plurality of of different size.Cut-off rule or its extended line 3 of two parts of described aluminum foil pad body 1 overlap, and can through the center-point of aluminum foil pad body 1, maybe can make the measure-alike of two-part aluminum foil pad body 1.
Embodiment
Helicopter Transmission System input stage gear is adjusted impression and the needed aluminium foil adjusting pad of backlash, the input stage driving gear of this type Helicopter Transmission System is relevant with the casing installation site to the input stage driven gear, the position of casing directly has influence on impression and the backlash index of gear, and casing relies on seven binding bolts to fix.Therefore, the structure of the aluminium foil adjusting pad between casing is: described aluminium foil adjusting pad comprises the aluminum foil pad body, the aluminum foil pad body is identical with the contour shape of casing attachment face, described aluminum foil pad body is divided into two parts, position at seven binding bolts is provided with groove, and the opening direction of described groove is the inside of casing.The thickness of described aluminium foil adjusting pad is 1.75mm, 1.70mm, 1.65mm, four sizes of 1.60mm, and the extended line of the cut-off rule of two parts of described aluminum foil pad body overlaps, and makes the measure-alike of two-part aluminum foil pad body.
When assembling, after casing is installed, the assembler unclamps bolt, casing is lifted slightly, respectively the aluminium foil adjusting pad appropriate section of different size is packed into from a side, then from opposite side, the aluminium foil adjusting pad of corresponding another part is packed into, binding bolt, check gear impression and backlash, until best gear engagement states is arranged.Result shows, is the best when the thickness of aluminium foil adjusting pad is 1.65mm.
