In fact, it has been a kind of normality that power transmission shaft needs axial fine setting, but transmission shafts be yet there are no report to a kind of axial adjusting device of finely tuning.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of axial adjusting device, and this axial adjusting device has very strong versatility and interchangeability, processes easyly, easy to maintenance, axially adjusts safe and reliable.
For achieving the above object, the utility model adopts following technical scheme:
A kind of axial adjusting device, this axial adjusting device comprises the propeller boss combination, pressing plate, the propeller boss cover, guide spiro rod, support body, worm screw, handwheel, worm gear case, coupling sleeve, nut, thrust ball bearing, connecting plate, standby cap and fixed cover, propeller boss combination is installed in the power transmission shaft tail end and is fixed by pressing plate and bolt, the bearing outer ring that propeller boss combination is disposed abuts against in the inside groove that propeller boss cover right side arranges and by fixed cover and bolt and is fixed, propeller boss cover left side connects with connecting plate by guide spiro rod, center configuration thrust ball bearing at connecting plate, the optical axis of worm screw right-hand member is fixed it by standby cap after passing thrust ball bearing, worm gear engagement in the external screw thread of worm screw left end and the worm gear case, worm gear in the worm gear case connects with handwheel again, the external screw thread in worm screw stage casing is engaged with nut, nut is fixed in the support body of welding formation, support body then is bolted on the frame afterbody relevant with the fixed conveyor axle, and coupling sleeve not only connects worm gear case but also connect support body by bolt.
Above-mentioned propeller boss combination comprises two chucks and a cover bearing, described two chucks are also relatively fixing in the middle of described bearing is placed, the internal diameter of described two chucks and the internal diameter of described bearing equal the external diameter of the described tail end of power transmission shaft, the external diameter of described two chucks is less than the internal diameter of propeller boss cover, and the inside groove internal diameter that the external diameter of described bearing and propeller boss cover right side arrange is complementary.
The gearratio of the worm gear engagement in the external screw thread of above-mentioned worm screw left end and the worm gear case 〉=60.
Owing to adopt as mentioned above technical scheme, the utility model produces following good effect:
1, of the present utility model simple in structure and practical, therefore the utlity model has very strong versatility and interchangeability, its processing is easy, easy to maintenance, it is safe and reliable axially to adjust.
2, the gearratio of the engagement of the worm gear in the external screw thread of worm screw left end and the worm gear case 〉=60, in the less situation of the external screw thread pitch of worm screw left end, hand wheel rotating one all worm screws are also less to the axial displacement of connecting plate and power transmission shaft, so that the axial displacement of power transmission shaft adjustment precision is very high, and can come by the dial that arranges on handwheel and the worm gear case the convenient axial displacement fine setting that realizes intuitively power transmission shaft.
Description of drawings
Fig. 1 is the structural representation of axial adjusting device;
Among the above-mentioned figure: the combination of 1-propeller boss; The 2-pressing plate; 3-propeller boss cover; The 4-guide spiro rod; The 5-support body; The 6-worm screw; The 7-power transmission shaft; The 8-handwheel; The 9-worm gear case; The 10-coupling sleeve; The 11-nut; The 12-thrust ball bearing; The 13-frame; The 14-connecting plate; The standby cap of 15-; The 16-fixed cover.
The specific embodiment
The utility model is a kind of axial adjusting device, and this axial adjusting device can be used in power transmission shaft to be needed in any mechanism of axial displacement adjustment, and the external diameter of setting the power transmission shaft tail end is given, and power transmission shaft is installed in the frame that disposes.
In conjunction with Fig. 1, the utility model comprises propeller boss combination 1, pressing plate 2, propeller boss cover 3, guide spiro rod 4, support body 5, worm screw 6, handwheel 8, worm gear case 9, coupling sleeve 10, nut 11, thrust ball bearing 12, connecting plate 14, standby cap 15 and fixed cover 16.
Above-mentioned propeller boss combination 1 comprises two chucks and a cover bearing, described two chucks are also relatively fixing in the middle of described bearing is placed, the internal diameter of described two chucks and the internal diameter of described bearing equal the external diameter of power transmission shaft 7 described tail ends, the external diameter of described two chucks is less than the internal diameter of propeller boss cover 3, and the inside groove internal diameter that the external diameter of described bearing and propeller boss overlap the setting of 3 right sides is complementary.When power transmission shaft 7 rotated, propeller boss combination 1 bearing that disposes and pressing plate 2 together rotated with power transmission shaft 7, but 3 in propeller boss cover does not rotate with propeller boss combination 1.
Guide spiro rod 4 is except having fixed connecting plate 14 functions, and guide spiro rod 4 also will pass through support body 5, so guide spiro rod 4 also can be interfered propeller boss cover 3 phenomenon that rotates.
The gearratio of the worm gear engagement in the external screw thread of above-mentioned worm screw 6 left ends and the worm gear case 9 〉=60, in the less situation of worm screw 6 pitch, handwheel 8 rotates 6 pairs of connecting plates 14 of all worm screws or the axial displacement of power transmission shaft 7 is also less, equal in 60 the situation such as equal 1.5mm and gearratio in described pitch, its handwheel 8 rotates 6 pairs of connecting plates 14 of all worm screws or the axial displacement of power transmission shaft 7 is 0.025mm through measuring and calculating.
The utility model only has when needing axial displacement to adjust with power transmission shaft 7 and just can support the use.
