The specific embodiment
Come the aligning gear of main frame of the present invention and gear case done further elaborating below in conjunction with drawings and embodiments, in the hope of expressing architectural feature of the present invention and concrete the application more cheer and brightly, but can not limit protection scope of the present invention with this.
Please consult first Fig. 1, Fig. 1 is that certain type ship engine installation is arranged sketch, and as seen from the figure, main power plant is being downward-sloping shape from screw propeller 11 up to gear case 12, but main frame 14 but is level to be installed, so must adopt angle compensation means joint coupling 13 between the two.After the gear case location positioning, how to come positioning host according to the gear case position, thereby make the output of main frame and the input end of gear case avoid flexion torsion on a plane.
Fig. 2 is the structural representation of the aligning gear of main frame of the present invention and gear case, and as shown in the figure, the aligning gear of a kind of main frame and gear case comprises flange disk 1, cylindrical sleeves 2 and centering needle point 5; One end of described cylindrical sleeves 2 is captiveed joint with flange disk 1, and the center of circle of cylindrical sleeves 2 is coaxial with the center of circle of flange disk 1; The other end of described cylindrical sleeves 2 is provided with a plurality of bolts hole, and effect is to adjust the position of described centering needle point 5 cylindrical sleeves 2 in, so that flange disk 1 is after rotating a circle, the track diameter that centering needle point 5 rotates is in 0.5mm.
The external diameter of one end of described centering needle point 5 and the internal diameter of cylindrical sleeves are complementary, and this end stretches in the cylindrical sleeves 2, and captive joint with cylindrical sleeves 2 through bolt hole by bolt 4, and the other end of centering needle point 5 is needlepoint type; On the outer wall of described cylindrical sleeves 2, also be provided with deep bracket 3, produce plastic deformation when preventing from carrying this device.
Described flange disk 1 is provided with a plurality of oblong through holes, this through hole evenly distributes centered by the center of circle, thereby have commonality in order to make this device be applicable to all kinds main frame gear case, the number of openings of design is 8, only need to use 3～4 holes during actual the use and fix and get final product.Be to consider commonality in addition equally, this device bolt hole adopts oblong to adapt to the main frame gear case flange of different sizes.
The manufacture method of the aligning gear of a kind of main frame of present embodiment and gear case comprises the steps:
1. mill out 8 oblong through holes at a thick diameter of about 20mm at the high flange disk 1 of 500mm left and right sides planeness, these through holes are uniform centered by the center of circle.Be the through hole that this device and gear case input flange or main frame output flange are fixed together.Thereby have commonality in order to make this device be applicable to all kinds main frame gear case, the number of openings of design is 8, only need to use 3～4 holes during actual the use and fix and get final product.Be to consider commonality in addition equally, this device bolt hole adopts oblong to adapt to the main frame gear case flange of different sizes.
2. with the about 400mm of length, internal-and external diameter be respectively 60 and an end of the cylindrical sleeves 2 of 80mm be welded on the flange disk 1, both centers of circle are overlapped, and orthogonal;
Can be eccentric in the time of for this device rotation of further assurance, the cylindrical sleeves after welding well can be respectively machined to 65mm and 75mm to its internal diameter external diameter on lathe, the precision of centering is more accurate.
3. at the outer wall of cylindrical sleeves 2 welding multi-disc deep bracket 3, generation plastic deformation when preventing from carrying this device.
4. the other end end at cylindrical sleeves 2 arranges a plurality of bolts hole along even circumferential.
5. prepare centering needle point 5, the external diameter of an end of centering needle point 5 is made with the internal diameter of cylindrical sleeves suitable, the other end of centering needle point 5 is processed into needlepoint type.Thereby the diameter of needle tip must enough littlely satisfy the accuracy of alignment requirement.
Fig. 3 is the use constitution diagram of the aligning gear of main frame of the present invention and gear case, as seen from the figure
This device is mounted to gear case input end flange 15 places of adjusted good position, selects suitable through hole according to its flange eye position, fastening good.Insert subsequently centering needle point 5, depth of penetration is moderate.Then screw bolt 4, need be adjusted to gear case input end flange rotary one all needle point rotational trajectory diameters in 0.5mm.Can vertically place the needle point place to observe the rotational trajectory that it marks at blank sheet of paper an A4 blank sheet of paper.Then this device same method is installed in host output end flange 16 places.Insert subsequently centering needle point 5, depth of penetration is moderate, and swivel bolt 4 equally must be so that one week of host output end flange rotary, and the needle point track is in the 0.5mm diameter circle.The rear centering that just can begin main frame and gear case that satisfies condition needs to adjust the location pushing tow bolt around the main frame, and the contact of both needle tips still keeps in touch the host output end flange rotary together after the week the most at last, and then centering is finished.
The results showed that the aligning gear of main frame of the present invention and gear case has characteristics simple in structure, easy to use, and its centering method is simple and reliable, precision is high.This device is widely used in the main frame gear case centering of various ship types.
