Abstract
The invention discloses a transfer gear positioning device for a hydraulic torque converter. A transfer gear is provided with a supporting table for supporting a pump wheel; the pump wheel is connected with the supporting table of the transfer gear, and runs synchronously along with the transfer gear; the transfer gear is supported on an output shaft through a bearing; the supporting table of the transfer gear extends by a step towards a pump wheel side; the outer circle of the step is connected with the inner hole of the pump wheel in a sleeve way, thereby forming positioning support of the pump wheel; the bearing is axially positioned through a retainer ring positioning outer ring and a positioning sleeve positioning inner ring. The transfer gear positioning device has the advantages that the pump wheel and the transfer gear are arranged on the same large-sized bearing, so that the negative influences of non-uniform bearing load, easiness in wear and the like caused by processing accuracy errors of two bearing holes and own processing error of the bearing in an original structure are eliminated, and the bearing capacity is increased; the axial play can be adjusted, and the bearing capacity and rotating accuracy of the bearing can be increased, so that the service life of the bearing is prolonged, and the working reliability of the hydraulic torque converter is greatly enhanced.
Description
Technical field
The present invention relates to technical field of engineering machinery, particularly relate to a kind of fluid torque converter transfer gear positioning device being applied to loader.
Background technique
At present, most loader adopts machinery-hydraudynamic drive, and the fluid torque converter main parts size of joining comprises hubcap, pump impeller, turbine assembly, guide wheel, output shaft, transfer gear, power take-off gear etc.
In fluid torque converter, hubcap and engine flywheel gear ring are directly joined merga pass bolt and are connected with pump impeller, therefore pump impeller and motor together rotate.Fluid is full of inside torque-converters, changes mechanical energy is the kinetic energy of fluid in pump impeller runner by pump impeller rotation, fluid relies on the effect of centrifugal force along the blade of the guiding impulse turbine of pump impeller blade, and turbine assembly is rotated, and fluid rushes at fixed guide vane then.According to the principle of active force and reaction force, high-speed punching can produce a reaction force to turbine assembly to the fluid of guide wheel, thus increases the output torque of turbine group.Turbine together with turbine hub rivet, then is connected with turbine output shaft by spline, and turbine output shaft is connected with shaft coupling by spline, transmission of power is given transmission system thereafter.
As shown in Figure 1, pump impeller and transfer gear are arranged on the bearing of two same model existing fluid torque converter respectively, and connected and fastening (as shown in Figure 2) with transfer gear by bolt, moment is passed to the power take-off gear engaged with it by transfer gear.Transfer gear positioning device is: transfer gear and pump impeller are separately fixed on two bearings, and one of them bearing contacts with transfer gear with pump impeller simultaneously, and they realize synchronous rotary work by Bolt Connection.Transfer gear and pump impeller bearing positioning hole are in actual manufacture process, and owing to not being machine in same procedure is with clamped one time, there is machining error, this error will cause with axle bearing load unbalanced; Even and also there is the difference of precision in the manufacture of same batch of the bearing of same model.These two differences are constantly amplified during frequent transitions with load change at torque-converters, two bearings are caused for a long time, to only have the half of a bearing or bearing being subject to load effect, unbalanced load effect makes bearing easily frayed, reduced lifetime, thus greatly reduces the reliability of fluid torque converter.
Summary of the invention
It is uneven that object of the present invention is just to provide the existing fluid torque converter transfer gear device axis bearing load of a kind of solution, and easily frayed, reduced lifetime, finally causes the fluid torque converter transfer gear positioning device of fluid torque converter Problem of Failure.
Solution of the present invention is such:
A kind of fluid torque converter transfer gear positioning device, comprise interconnective transfer gear, pump impeller, it is characterized in that: described transfer gear is provided with the supporting station for supporting pump impeller, described pump impeller is connected with the supporting station of transfer gear follows transfer gear run-in synchronism; Described transfer gear is supported on output shaft by bearing.
Technological scheme also comprises more specifically: the supporting station of described transfer gear is for stretch out a step to pump impeller side, and this step cylindrical socket pump impeller endoporus forms the positioning support to pump impeller.
Further: described pump impeller pump impeller side is provided with bolt and squeezes into mouth, squeeze into mouth bolt from bolt and squeeze into transfer gear and adopt screw connection structure to connect with fastening.
Further: described transfer gear is used for bearings mounted bore openings towards pump impeller side, has groove, be provided with back-up ring at this groove place in hole.
Further: described groove is in back-up ring and bearing installs the position that rear bearing has 0.05mm-0.15mm shaft clearance.
Further: the supporting surface of described bearing is positioned at the below of transfer gear and pump impeller junction.
Further: described bearing locates outer ring by back-up ring, setting sleeve locates inner ring, realizes axially locating.
Advantage of the present invention is that the present invention is equivalent to pump impeller and transfer gear to be arranged on same bearing, eliminate in original structure because the error of two bearing hole machining accuracies and bearing self machining error cause axle bearing load uneven, the easily adverse effect such as frayed: transfer gear is arranged on a larger-size bearing simultaneously, improves bearing capacity; Outer ring, bearing one end utilizes back-up ring to locate, and can carry out the adjustment of axial internal clearance, can improve bearing capacity and the running accuracy of bearing, thus improve the working life of bearing, greatly improve the functional reliability of fluid torque converter.
