Abstract
The invention relates to an axial damping connection sleeve capable of eliminating axial force of a tapered compression coupling shaft. The axial damping connection sleeve comprises a damping connection sleeve body (1), a pump transmission shaft (2), a nut (3) and a transmission gear (4). An internal spline hole is formed in the transmission gear (4), the damping connection sleeve body (1) is connected to the pump transmission shaft (2) through the nut (3) in a pressed manner and is connected with the transmission gear (4), a tapered inner hole (5) is formed in the interior of the damping connection sleeve body (1) while the exterior of the same is provided with a spline exterior circle (6), another internal spline hole is formed in a shaft neck of the pump transmission shaft (2), the tapered inner hole (5) of the damping connection sleeve body (1) is connected with a tapered section of the pump transmission shaft (2), and the spline exterior circle (6) of the damping connection sleeve body (1) is connected with the internal spline hole of the shaft neck of the transmission gear (4). The standard structure of the pump transmission shaft is ensured not to be moved, and axial high-frequency impact brought by high-speed rotation of a helical gear is eliminated.
Description
Technical field
The invention belongs to gear train assembly, be specifically related to a kind of axial damping joint sleeve that taper compresses joining shaft axial force of eliminating.
Background technique
Gear transmission is the most general kinds of drive of engine accessory power rating transmission such as water pump, oil pump, variable displacement pump.Helical gear Transmission is compared with Spur Gear Driving running is more steady, intensity is better, is the stationarity that guarantees reliability of structure and compactedness and transmission, and Helical gear Transmission has better advantage.But Helical gear Transmission can produce certain axial force.For engine accessory power rating drive line, if there is no axial transferring structure, axial force can be delivered on the transmission shaft of annex by the direct geared connecting with annex.And finally have influence on the service behaviour of this annex.
On present stage diesel engine, the driving of two variable displacement pumps has all adopted helical gear drivetrain, actuation gear is compressed and is directly fixed on variable displacement pump transmission shaft by taper, cause gear can produce larger axial force at work, therefore be subject to the axial impact force of high frequency with the variable displacement pump of its rigid joint, made that its service behaviour is unstable, the life-span reduces, and final damage.
Summary of the invention
The present invention compresses in order to solve taper in gear transmission the problem that joining shaft produces axial force, and a kind of axial damping joint sleeve that taper compresses joining shaft axial force of eliminating is provided.
The technical solution used in the present invention: a kind of axial damping joint sleeve of eliminating taper compression joining shaft axial force, comprise damping joint sleeve 1, pump housing transmission shaft 2, nut 3 and driving gear 4, wherein on driving gear 4, be provided with inner splined hole, damping joint sleeve 1 is compressed and is connected on pump housing transmission shaft 2 by nut 3, damping joint sleeve 1 is connected with driving gear 4, the inside of damping joint sleeve 1 is cone-shaped inner hole 5, outside is spline cylindrical 6, on axle journal on driving gear 4, be provided with inner splined hole, the cone-shaped inner hole 5 of damping joint sleeve 1 is connected with the conical section on pump housing transmission shaft 2, spline cylindrical 6 on damping joint sleeve 1 is connected with the inner splined hole on axle journal on driving gear 4.
The present invention compared with prior art its beneficial effect is: the present invention adopts after the damping joint sleeve of cone-shaped inner hole and spline cylindrical structure, the axial force that gear is produced is delivered on transmission case by the thrust of bearing, both the normal structure that had guaranteed pump housing transmission shaft need not move, and has eliminated again the axial high-frequency percussion power that helical gear High Rotation Speed brings.Thereby guaranteed highly reliable, high steady, the long lifetime service performance of annex pump.
Accompanying drawing explanation
Fig. 1 is the structural representation of damping joint sleeve of the present invention;
Fig. 2 is that damping joint sleeve assembles and quarrels in transmission system.
Embodiment
Eliminate the axial damping joint sleeve that taper compresses joining shaft axial force, as shown in Figure 2, the outer ring interference of clutch shaft bearing 7 is installed in the hole of transmission case 8, and inner ring transition is installed on the axle journal of driving gear 4.Then the outer ring interference of the second bearing 12 is installed in the hole of bearing support 9, inner ring transition is arranged on driving gear 4 axle journals, and bearing support 9 is installed on transmission-case cover 10.The direct taper of damping joint sleeve 1 use nut 3 is pressed on pump housing transmission shaft 2, after screwing, the pump housing 11 is pushed in transmission-case cover 10, the spline cylindrical 6 of damping joint sleeve 1 also inserts in the inner splined hole of driving gear 4 simultaneously, and pump housing transmission shaft 2 connects smoothly with driving gear 4.Then with bolt 13, the pump housing is fixed.
When there is no damping joint sleeve 1, driving gear 4 axle journal endoporus are taper, will directly be pressed on pump housing transmission shaft 2 during assembling, and the axial force of driving gear 4 just will directly pass on the pump housing; Install after damping joint sleeve 1, bore changes inner splined hole into, and damping joint sleeve 1 is that spline cylindrical 6, inside are cone-shaped inner hole 5.Damping joint sleeve 1 is directly pressed on pump housing transmission shaft 2 by cone-shaped inner hole 5, spline cylindrical 6 is inserted in driving gear 4 inner splined holes, thereby by splined, carry out the rotation of driven pump.Spline is not have axial force, so the pump housing also can not be subject to the impact of axial force again, and the axial force that gear produces is delivered to the thrust by bearing on transmission case.Axial damping device is designed to inner conical, external splines structure, has both guaranteed that the normal structure of pump housing transmission shaft need not move, and has eliminated again the axial high-frequency percussion power that helical gear High Rotation Speed brings.Thereby guaranteed highly reliable, high steady, the long lifetime service performance of annex pump.
When pump work is undesired, what be first damaged is damping joint sleeve 1, thereby make to close heavy part driving gear, has avoided damage fault.Economy and the reliability of system have been increased.
