Abstract
The utility model provides a cross axle of a universal coupler, which is used for various heavy machines. The cross axle comprises an inner core, a hardening layer and a carburized hardening layer in sequence from inside to outside. The surface of the cross axle is provided with the carburized hardening layer with the thickness of 0.8-1 mm and the mass percent content of carbon of 0.8-1.05%; and the hardening layer with the thickness of 1-7.2 mm is arranged between the carburized hardening layer and the inner core. The hardness of the surface of the cross axle can reach HRC58-62 due to the existing carburized hardening layer and hardening layer. Furthermore, the mechanical strength of the cross axle is obviously improved. The cross axle has advantages of higher strength, higher toughness and strong carrying capacity so that the requirements of various heavy machines on the working torque of the universal coupler can be met.
Description
Technical field
The utility model relates to a kind of cross axle of Hooks coupling universal coupling, and this cross axle is specially adapted to connect and carries greatly and out-of-alignment two transmission shafts.
Background technique
The cross axle that is used for the whole fork head type cross-axle universal shaft coupling of heavy machineries such as rolling machinery, Hoisting Machinery at present all adopts the common low carbon alloyed steel to process, and its bearing capacity is poor.And Hooks coupling universal coupling is when low-speed running, and cross axle will bear stronger impact load, bears bigger moment of torsion.In order to guarantee the performance of Hooks coupling universal coupling; Usually through increasing the Operating torque that the coupling volume improves coupling; But increase not only waste material of volume, increase cost, also can cause coupling the problem that operation is not steady, mechanical property is unstable and working life is short to occur simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of cross axle of Hooks coupling universal coupling, uses this cross axle under the situation that does not increase Hooks coupling universal coupling boundary dimension, to guarantee that coupling bears bigger moment of torsion when the low-speed running operating mode.
The technological scheme that realizes the utility model purpose is that the cross axle of Hooks coupling universal coupling is followed successively by inner core, quench-hardened case and carburizing quench-hardened case from the inside to the outside; The cross axle surface is the carburizing quench-hardened case of the steel for carburizing of 0.8～1mm, is the quench-hardened case of 1～7.2mm between carburizing quench-hardened case and the inner core.
And inner core is low-carbon alloy structural steel 20CrMnTi; Between inner core and the quench-hardened case, and be the gradual change type layering interfaces between quench-hardened case and the carburizing quench-hardened case.
The cross axle of the Hooks coupling universal coupling that provides because of the utility model has the quench-hardened case of 1～7.2mm outside the inner core of low-carbon alloy structural steel 20CrMnTi; It is the carburizing quench-hardened case of 0.8-1.05% that quench-hardened case also has the carbonaceous amount percentage composition of 0.8～1mm; So this cross axle tool high toughness and higher intensity; Can reach HRC58-62 through its surface hardness of test, inner core hardness can reach HRC33-38, and bearing capacity is very strong; Under the situation that does not increase Hooks coupling universal coupling boundary dimension, can satisfy the requirement of Operating torque.
Description of drawings
The cross sectional representation of the Hooks coupling universal coupling cross axle that accompanying drawing 1 provides for the utility model.
Wherein 1, inner core; 2, quench-hardened case; 3, carburizing quench-hardened case.
Embodiment
Shown in accompanying drawing 1; The cross axle of the Hooks coupling universal coupling that is used for heavy machineries such as rolling machinery, Hoisting Machinery that the utility model provides is followed successively by inner core 1, quench-hardened case 2 and carburizing quench-hardened case 3 from the inside to the outside; This cross axle is a basic material with low-carbon alloy structural steel 20CrMnTi, and after carburizing, quenching, its inner core 1 still is low-carbon alloy structural steel 20CrMnTi; But the outermost surface of cross axle becomes the carburizing quench-hardened case 3 of the steel for carburizing that is 0.8～1mm; Be the quench-hardened case of 1～7.2mm between carburizing quench-hardened case 3 and the inner core 1, between inner core 1 and the quench-hardened case 2, and be the gradual change type layering interfaces between quench-hardened case 2 and the carburizing quench-hardened case 3.Owing to have carburizing quench-hardened case 3 and quench-hardened case 2; The carbonaceous amount percentage composition of steel for carburizing is 0.8-1.05%; Make the cross axle surface hardness of the Hooks coupling universal coupling that the utility model provides to reach HRC58-62; And the mechanical strength of cross axle also has clearly raising, and tensile strength can be not less than 1250N/mm
2, yield limit can be not less than 900N/mm
2, impact toughness is greater than 70J0.Therefore the cross axle self of the Hooks coupling universal coupling that provides of the utility model has higher intensity and toughness, and bearing capacity is strong, can satisfy the Operating torque requirement of various heavy machineries to Hooks coupling universal coupling fully.
