Abstract
The utility model provides an output mechanism of the rotary gear reducer is provided with a planetary wheel frame [5], output gear axis [7] is arranged on the axle center of the planetary wheel frame; the planetary wheel [3] is installed on the same circumference of the planetary wheel frame along the axle [4], wherein the planetary wheel frame and output gear axle are a part. Said output mechanism of the rotary gear reducer adopts the planetary wheel frame and output axle as a piece of part, that is said the planetary wheel frame and the output axle are made of a block of the same raw material, which make both of them not have the possible looseness of connection and simplify the processing program and installation program with high precision. In addition, a concave is able to be processed on the surface of the planetary wheel frame close to the sun wheel axle to avoid the friction and collision between sun wheel axle and planetary wheel frame.
Description
Technical field the utility model relates to a kind of output mechanism of rotary reducer, belongs to driving mechanism.
The background technique rotary reducer, be applied to a kind of device with deceleration between oil hydraulic motor and the excavator platform pivoting support and increase output torque, its kind of drive is sun gear and the planet wheel engagement that is connected on the motor spindle, internal tooth engagement on planet wheel and the internal tooth housing connects the output gear axle by planetary wheel carrier again.Like this, planet wheel, planetary wheel carrier and output gear axle constitute the output mechanism of rotary reducer.For preventing that the output gear axle from deviating from from planetary wheel carrier, the applicant discloses the technological scheme that a kind of end that planetary wheel carrier is installed installs and fixes planetary wheel carrier with floor clip and round nut on the output gear axle in Chinese patent 01227879.3 " hydraulic shovel rotary reducer ".But this technological scheme, the one, still can not be completely free of the loosening phenomenon between planetary wheel carrier and output shaft; The 2nd, component are more, processing inconvenience.
Summary of the invention is at above-mentioned deficiency, and the technical problems to be solved in the utility model has the amount of parts of thoroughly stopping loosening between planetary wheel carrier and output shaft and reducing output mechanism, thereby proposes a kind of output mechanism of reliable, brief rotary reducer.
The output mechanism of the rotary reducer that the utility model provides has planetary wheel carrier, and the output gear axle is arranged on the planetary wheel carrier axle center, and planet wheel is installed in axle on the same circumference of planetary wheel carrier, and wherein planetary wheel carrier and output gear axle are parts.
The output mechanism of the rotary reducer that the utility model provides, as a part, promptly planetary wheel carrier and output shaft are made with a raw material with planetary wheel carrier and output shaft, and not only both no longer exist and connect loosening possibility, and procedure, installation procedure all obtain simplifying, and precision is also higher.On the face of the contiguous sun wheel shaft of planetary wheel carrier, also can process concave surface in addition, bump to avoid the wiping between sun wheel shaft and planetary wheel carrier.
Appended drawings is that figure cuts open in the utility model one embodiment's office.
The introduction of embodiment present embodiment be XJE5.0 type rotary reducer, mainly use on the excavator that oil hydraulic motor is used as power.As shown in drawings, on the main shaft 1 that is connected with oil hydraulic motor sun gear 2 is installed in the rotary decelerating box body, the planet wheel 3 that meshes with sun gear is installed on the same circumference of a planetary wheel carrier 5 with axle 4.Connect output gear axle 6 on the planetary wheel carrier axle center, that is to say that planetary wheel carrier 5 and output gear axle 6 are one, make through gold machining again after breaking into blank through forging with a raw material.The output gear axle is connected with output gear 7 with spline pair.
Claims (1)
1, a kind of output mechanism of rotary reducer has planetary wheel carrier, and the output gear axle is arranged on the planetary wheel carrier axle center, and planet wheel is installed on the same circumference of planetary wheel carrier with axle, it is characterized in that wherein planetary wheel carrier and output gear axle are parts.
