Abstract
The utility model provides a press-mounting tool for a diesel engine hydraulic pump gear bearing. The press-mounting tool for the diesel engine hydraulic pump gear bearing comprises a pressing rod body and a positioning block, wherein a handle is arranged at the upper portion of the pressing rod body, a pressing plate is arranged in the middle of the pressing rod body, a positioning rod is arranged at the lower portion of the pressing rod body, and a positioning boss is arranged at the upper portion of the positioning block. The press-mounting tool for the diesel engine hydraulic pump gear bearing is convenient to operate, is good in universality, is capable of mounting the bearing correctly, stably and rapidly, improves press-mounting efficiency, and guarantees press-mounting quality.
Description
Technical field
The utility model relates to the erecting tools of diesel engine part, specifically diesel engine hydraulic pump gear bearing press-mounting tool.
Background technology
Hydraulic pump gear is important part in the transmission of diesel engine gear train.The quality of hydraulic pump gear bearing press mounting quality directly has influence on the transmission of whole diesel engine gear train.Now when press-fiting the hydraulic pump gear bearing, because the instrument that uses is undesirable, tend to cause the bearing deviation of being pressed, press-fit the backgear chamber and abnormal sound occurs, affect diesel engine performance.Even, can damage bearing by pressure, cause unnecessary loss.
The utility model content
The purpose of this utility model is a kind of satisfactory instrument of design, can steadily, correctly be pressed into bearing, guarantees the installation quality of bearing.
The utility model is to realize like this purpose of design:
Make cylindrical depression bar body 9 and truncated cone-shaped locating piece 8.Make the top of depression bar body 9 with the handle 1 of neighboring annular knurl; The middle part is with pressing plate 2; The bottom is with making with splined hole 6 backstay 3 of matched in clearance.Make the top of locating piece 8 with making with splined hole 6 positioning boss 7 of matched in clearance.
During use, the positioning boss 7 of locating piece 8 upwards is well placed, the splined hole 6 of gear 5 one ends is enclosed within on positioning boss 7, again bearing 4 is enclosed within the bearings mounted position of needs on gear 5 tops, then backstay 3 is inserted in the splined hole 6 of gear 5 upper ends, make the lower surface of pressing plate 2 press close to the upper surface of bearing 4, slowly be pressed into from handle 1 upper end with hydraulic press.After the bearing press mounting on gear 5 tops, gear 5 two ends are exchanged, press-fited another bearing 4.
The utility model due to the splined hole 6 that gear 5 two ends are arranged respectively with the matched in clearance of positioning boss 7 and backstay 3, play the supplemental support effect, guarantee steady positioning.Can make bearing 4 by correctly, be pressed into reposefully, deviation, can not damaged by pressure yet.
Description of drawings
Fig. 1 is the utility model structural representation.
OnSequence number in figure: handle 1, pressing plate 2, backstay 3, bearing 4, gear 5, splined hole 6, positioning boss 7, locating piece 8, depression bar body 9.
The specific embodiment
Below in conjunction with accompanying drawing, a non-limiting examples is illustrated.
Make cylindrical depression bar body 9 and truncated cone-shaped locating piece 8.Make the top of depression bar body 9 with the handle 1 of neighboring annular knurl; The middle part is with pressing plate 2; The bottom is with making with splined hole 6 backstay 3 of matched in clearance.Make the top of locating piece 8 with making with splined hole 6 positioning boss 7 of matched in clearance.
Use the utility model, during pressing bearing 4, correct, steady, quick.Can raising press-fit efficient, guarantee to press-fit quality.
