Abstract
Sealing equipment for the exported oil from a planet gear transmission case is a special sealing structure used on a duct typed motor for preventing the oil in the planet gear transmission case from leaking out, comprising a whole body formed by a sealing ring built in a third class bracket, a shim for inner tooth seat and a retaining ring. The sealing ring is built in the axis of the third class bracket and is clung to the plane sealing shim on one end of the third class bracket. Central hole of the inner tooth seat matched with the third class bracket has projected steps, which is matched with the plane sealing shim. The original radial sealing on the output shaft is substituted by axial plane sealing, therefore, the sealing area is enlarged to improve the sealing performance. When the transmission case works, a constant pressure acts on the end of the third class bracket, so that the plane sealing shim presses out the projected steps at the central hole of the inner tooth seat, therefore, the problem of oil leaking is solved. Although the plane sealing shim would become attenuated for abrasion, the sealing performance is still well through the aging test and it solves the problem of oil leaking thoroughly which bothers the manufacture factory of the duct typed motor.
Description
Technical field
The utility model relates to the sealing mechanism that prevents on a kind of tube shaped electric machine that the planetary transmission leakage of oil from using, planetary transmission output shaft seal arrangement.
Background technique
Use on the existing market and commercially available rolling shutter door, window on, oil leakage phenomenon often takes place in tube shaped electric machine planetary transmission output shaft place, though manufacturer has adopted a lot of measures, as increasing dress O RunddichtringO at output shaft of gear-box and cooperation place, internal tooth block set aperture, just begun fortunately, but time long back ring wear, it is big that the aperture becomes, again oil leakage phenomenon can take place, this is a long-term next unsolved difficult problem, and tube shaped electric machine manufacturer is puzzling always.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of planetary transmission output shaft seal arrangement is provided, and simple, the easily installation of sealing device structure, but solved the oil tight difficult problem in planetary transmission output shaft place.
The technical scheme in the invention for solving the above technical problem is: planetary transmission output shaft seal arrangement, by being installed on three grades of supports, seal ring and internal tooth block set constitute with the whole institute that pad, jump ring are linked to be, described seal ring is the dull and stereotyped gasket seal that is installed on three grades of support shafts and is close to three grades of support one end faces, the central hole of the internal tooth block set that cooperates with three grades of supports has the protrusion step, and dull and stereotyped gasket seal cooperates with the protrusion step.
Compared with prior art, advantage of the present utility model is: the seal ring that adopt in original output shaft place is a radial force, seal ring rotates with output shaft and weares and teares, and time long back seal ring diminishes, Kong Bianda, can not solve the leakage of oil problem with dull way of changing a seal ring.This dull and stereotyped gasket seal and the seal arrangement that protrudes the step formation, the end face that dull and stereotyped gasket seal is close to three grades of supports is always followed three grades of supports and is rotated together, and dull and stereotyped gasket seal is close to the protrusion step of internal tooth block set central hole always, although the time is with after long, seal ring can wear and tear but also be the end wear attenuation, but because of it is subjected to the deceleration pressure effect that gearbox work passes over always, still be close to always and protrude on the step, improving original radial is that axial seal has strengthened sealing area, so good airproof performance, and the output shaft rotating speed hangs down at 15 commentaries on classics/per minutes and rotates, and this rotating speed just meets the pad of this slow-speed of revolution performance.Through more than 30,000 aging tests, proved that it has good sealing effect, if calculate for 3 times with Yishanmen, one day switch of window, this seal arrangement also can be used about 20 years.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Third-level planetary gear transmission assembly 9 is installed in the external tooth cover 8, and external tooth cover 8 utilizes the internal thread and the internal tooth block set 3 at two ends, and the outside thread of internal tooth upper shield 10 ends and pad 2, jump ring 1 connect into integral body, and it is the same with prior art to constitute planetary transmission.
The planetary transmission output shaft promptly is three grades of supports of planetary transmission, and three grades of supports are made of the end face 7 of three grades of support shafts 6 with the band pin, also are the same with prior art.
Now only increase by one and protrude step 4 at internal tooth block set 3 center hole inside edges, on three grades of support shafts 6, be close to end face 7 places one dull and stereotyped gasket seal 5 is installed, and make dull and stereotyped gasket seal 5 be close to protrusion step 4 work formation planetary transmission output shaft seal arrangements, be special-purpose sealing configuration.
During use, driven by motor one-level sun gear rotates, planetary transmission work is through three grades of transmissions, slow down, drive the i.e. three grades of support rotation output nominal torques of output shaft at last, rotate just can reach by the runner that connects on the output shaft (figure does not draw) again and roll or put down sunshade, rolling shutter door, the purpose of window, because of planetary transmission work and through the transmission of one-level level, slow down and constantly transmit backward, always there is a pressure to act on all the time on three grades of supports at last, dull and stereotyped gasket seal 5 on it is close to always is sealed in and protrude step 4 places, and rotate with output shaft, thereby the lubricant grease in the gearbox can not flowed out, solved the oil tight problem in output shaft place.
Claims (3)
1, a kind of planetary transmission output shaft seal arrangement, by being installed on three grades of supports, seal ring and internal tooth block set (3) constituted with the integral body that pad (2), jump ring (1) are linked to be, it is characterized in that described seal ring is the dull and stereotyped gasket seal (5) that is installed on three grades of support shafts (6) and is close to three grades of support one end faces (7), the central hole of the internal tooth block set (3) that cooperates with three grades of supports has protrusion step (4), and dull and stereotyped gasket seal (5) cooperates with protrusion step (4).
2, planetary transmission output shaft seal arrangement according to claim 1 is characterized in that internal tooth block set (3) center hole inside edge increases by one and protrudes step (4).
