Abstract
The utility model relates to a hard axle-mounted reducer which is a key improvement to the patent of an axle-mounted cycloid reducer (ZL98116412.9). The utility model may prevent oil leakage completely, slow down the temperature rising and prolong the service life. The utility model is characterized in that a mazy oil splash ring is arranged between an input shaft and an output disc so that lubricant is able to be threw directly from the surface of the outer cycle of the oil splash ring to the bottom, thereby getting rid of the oil seal at the input end and slowing down the temperature rising. Besides, the utility model adopts a pin wheel housing for rotation, thereby improving the lubricating state of all driving components in a shell and ultimately lengthening the service life of machine elements and slowing down the temperature rising.
Description
The utility model relates to shaft-mounted speed reducer technical field, the shaft-mounted speed reducer of a kind of hard flank of tooth.
The shaft-mounted speed reducer of cylindrical gears that patent of invention axially mounted cycloidal reducer (ZL98116412.9) compares has following advantage: in light weight, boundary dimension is little, and long service life and noise are low or the like.Thereby be widely used on noria, belt conveyor and the scraper conveyor, be substituted imitated external box shaft-mounted speed reducer.But the user reflects that oil leakage phenomenon occurs now and then in actual use, by serious analysis, finds that friction causes the gap of lubricant oil between input shaft endoporus and output axle journal toward external leakage because the input end oil sealing runs up.
The purpose of this utility model is that this invention is further improved, and makes new structural type not only prevent leakage of oil, and will reduce the temperature rise of complete machine, increases the service life.
Embodiment of the present utility model: the oil sealing that 1. removes input end; 2. an oil thrower ring is arranged between input shaft capacity eccentric bearing and output shaft disk, and the corresponding wedge-like circular hole of oil thrower ring and pin wheel housing constitutes the labyrinth shape sealing configuration simultaneously, in case leak-stopping oil; 3. pin wheel housing connects with the output shaft disk, and the rotation of pin wheel housing improves whole driving component on the one hand and is in good lubricating status, makes the lubricant oil oil temperature in the casing at equilibrium on the other hand, to quicken heat radiation.
Advantage of the present utility model: except that the advantage that keeps former invention, guarantee oil-proof, temperature rise is low, longer service life.
Accompanying drawing is the utility model embodiment's a structure principle chart.
Below in conjunction with accompanying drawing the utility model is described in detail,, only architecture advances is made description because working principle is identical with former patent of invention, thereby will not repeat.
With reference to accompanying drawing.The shaft-mounted speed reducer of a kind of hard flank of tooth mainly is made of capacity eccentric bearing [9], cycloid wheel [3] and pin gear, and wherein pin gear is made up of pin wheel housing [2], needle pin and needle guard, it is characterized in that:
(1) pin wheel housing [2] connects with output shaft [6] disk, output shaft has shoulder hole in [6], wherein macropore is used for whole speed reducer is contained on the transmission shaft of matched host machine, a bolt is arranged in the aperture, fitted shaft in order in the tension macropore comes off from the matched host machine transmission shaft in the running to prevent speed reducer;
(2) cycloid wheel [3] of pin wheel housing [2] and pin wheel housing inner chamber, capacity eccentric bearing [9] is whole places within the casing [1], pin [4] is fixed tightly on the end cap [11] by the retaining ring [10] with its close-fitting, end cap [11] connects one with casing [1];
(3) between capacity eccentric bearing [9] on the sleeve shape input shaft [14] and output shaft [6] disk, an oil thrower ring [7] is arranged, wedge shape circular hole corresponding on oil thrower ring limit circular portion and the pin wheel housing constitutes labyrinth seal structure, leaks from the clearance portion between input shaft and the output shaft to prevent lubricant oil.
