Description
Technical field:
The utility model belongs to mechanical transmission technical field, and in particular to a kind of adjustable super torsion of high-speed overload shafting
Protect structure.
Background technique:
The output shaft of certain type high-speed overload epicyclic gearbox testpieces (hereinafter referred to as testpieces) has transmitting power big
(20000Kw)；The characteristics of exporting revolving speed high (8000r/min), and testpieces is in development phase, structure type maturity
Difference, thus its reliability is low, causes the safety of testpieces and its coordinative experiments device low.To improve testpieces and matched
Safety of the exerciser in field investigation, and the ultimate load of its safe handling is obtained, it need to be convenient for disassembly and assembly in exerciser installation,
The adjustable flexible structure of bearing capacity.
Utility model content:
To solve the above-mentioned problems, the utility model provides one kind to can be realized convenient for disassembly and assembly and bearing capacity adjustable
Adjustable super torsion protection structure (super turn round hereinafter referred to as is adjusted and protects structure), turns round guard pin by the way that change is super with this structure
The number and structure of component not only can be improved the safety in field investigation of testpieces and matched exerciser and can be obtained
The ultimate load of its safe handling.It is high, compact-sized with working speed, versatility is high, disassembly is quick, it is reliable, effectively evade
Testpieces destroys the characteristics of risk.
The technical solution adopted in the utility model are as follows: a kind of adjustable super torsion protection structure of high-speed overload shafting, including it is outer
Drive shaft system, external bearing block, intermediate solid drive shaft system, adjustable super turn round protect pin assemblies and anti-winged pressing plate；With internal spline interface
The outer drive shaft system of structure is connect with high-speed overload epicyclic gearbox；The external bearing block is connect with gear case body,
The outer drive shaft system and intermediate solid drive shaft system connects by adjustable super protection pin assemblies of turning round, the anti-winged pressing plate by bolt and
The connection of intermediate solid drive shaft system.
The utility model has the beneficial effects that providing a kind of multi-functional installation interface conversion machine that can be realized simulation loading
Tool structure realizes simulation hydraulic pump load test using reduction gear box is configured after the mechanism.Working speed is high, compact-sized,
Versatility is high, disassembly quickly, it is reliable, the characteristics of protecting casing, effectively improve the stability of shafting, be easy to promote on a large scale and
It uses.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of embodiment one；
Fig. 2 is an application schematic diagram of the embodiment one in certain type high-speed overload epicyclic gearbox Power close exerciser.
Specific embodiment:
Embodiment one
Referring to Figures 1 and 2, a kind of high-speed overload shafting is adjustable super turns round protection structure, including outer drive shaft system 1, external
Bearing block 2, intermediate solid drive shaft system 3, adjustable super turn round protect pin assemblies 4 and anti-winged pressing plate 5；With described in internal spline interface structure
Outer drive shaft system 1 is connect with high-speed overload epicyclic gearbox；The external bearing block 2 is connect with gear case body, the unofficial biography
Moving axis system 1 is connect with intermediate solid drive shaft system 3 by adjustable super protection pin assemblies 4 of turning round, and the anti-winged pressing plate 5 passes through bolt and interior biography
3 connection of moving axis system.
The adjustable torsion protection structure that surpasses is by outer drive shaft system, external bearing block, intermediate solid drive shaft system, adjustable super torsion guard pin
Component, anti-winged pressing plate composition and corresponding installation are formed with standard component.Testpieces exports end interface barreled tooth flank and installation seam allowance is fixed
Bit architecture composition, the adjustable super outer drive shaft system of protection structure of turning round are connected with testpieces casket output end external splines, for revolving speed and
The installation fixing structure of the transmitting of power, external bearing block and testpieces cabinet is cooperated by using cylinder and bolt is fixed on examination
It tests on part, the end flanges of intermediate solid drive shaft are connected by hinged bolts with the shaft coupling of coordinative experiments platform.Intermediate solid drive shaft system with
Outer drive shaft system protects pin assemblies connection by several adjustable super turn round, and the torque of shafting transmitting protects structure by several super torsions
Intermediate shear face bear, thus change the super number for turning round protection pin assemblies and the design for changing intermediate shear face inner hole and exit orifice
Size, it can be achieved that different torque super torsion defencive function.
Because the adjustable super input flange for turning round protection structure intermediate solid drive shaft system by positioning spigot and is bolted, thus can
Changed according to the different input interfaces of different tests part.Intermediate solid drive shaft system ties up to exerciser transmitting torque with outer transmission shaft and is setting
It is opposing stationary relationship when below Dingan County's total head.When transmitting torque when setting safety value or more, inside and outside drive shaft system connects
The adjustable super protection structure of turning round connect is broken, and makes the transmitting torque load of exerciser less than on testpieces, and interior transmission
Shafting has independent spring bearing, externally drive shaft system will not cause undesirable influence, and anti-winged pressing plate effectively prevents super torsion
The damage for the shaft that flies out when guard pin fracture, therefore the adjustable super design for turning round protection structure is with reliable, protection test part
The characteristics of.And the adjustable super presence for turning round protection structure reduces the length of shaft coupling, improves the support stiffness of shafting, from
And the characteristics of improving the critical speed of shafting, the stability of shafting can be effectively improved.High, compact-sized with working speed,
Versatility is high, it is quick, reliable to dismantle, effectively evades the characteristics of testpieces destroys risk.
