Abstract
The present utility model provides a rotary gear reducer having often-closed friction-braking mechanism and planetary reduction mechanism in the housing including a motor base [5], a oil cylinder body, a friction plate base, a bearing base of the planetary wheel frame and a internal tooth housing [8], wherein the oil cylinder body, friction plate base and planetary support bearing base are a part [6]. The rotary gear reducer, provided by the utility model designed with several parts on the housing as a part on the premises of meeting the requirement for axis processing, reduces the difficulty for installation, decreases the utilization of the sealing elements, reinforces the installation and improves the performance preventing the leakage of the anti-oil material, in addition, avoids the processing procedures of the side surface of the original parts connected in the part. It follows that the rotary gear reducer provided by the utility model saves the processing cost and installation cost and improves the usage performance.
Description
Technical field the utility model relates to a kind of rotary reducer, belongs to driving mechanism.
The background technique rotary reducer is applied to the deceleration between oil hydraulic motor and the excavator platform pivoting support and increases a kind of device of output torque, and there is normally closed friction disc brake mechanism its input part, and output has planetary gear speed reducing mechanism.The structure of normally closed friction disc brake mechanism is that friction plate assembly is connected with input shaft with spline pair, there is the spring that is supported on the rotary reducer motor seat to press on the friction plate through piston block, friction plate makes its outer rim and friction bar friction catch through the pressurization radial expansion.Piston block is one the reducing piston of step to be arranged, and cooperates with the reducing cylinder body that step is arranged equally.Their major diameter is partly pointed to spring, and the sealing of Sealing and cylinder body is arranged at the piston block two ends, piston block top bar and the cylinder body step between a space is arranged, this space has oil circuit to be communicated with outside the cylinder body.When oil circuit during to the oiling of this space, oil pressure antagonistic spring elastic force loosens the compression of piston to friction plate, makes the friction plate radial contraction, reduces the frictional force between its outer rim and friction bar, and braking force is reduced until disappearance.In the past, on rotary reducer, the motor seat, friction bar, cylinder body, planetary wheel carrier bearing support, the internal tooth housing that play the housing effect all existed as single component.Therefore to adopt group leader's bolt that planetary wheel carrier bearing support and internal tooth housing are linked together when mounted, adopt another group leader's bolt that motor seat, cylinder body, friction bar and planetary wheel carrier bearing support are linked together, also to use many Sealings to seal between the each several part end face, in case cold oil, lubricant oil, pressure oil that non-return changes in the speed reducer leak.As seen this structure not only installs inconvenience, and the performance of the precision of installing and soundness, anti-oil plant seepage is all not enough.
Summary of the invention is at above-mentioned defective, and the utility model will solve as the too much technical problem of the part of housing, to provide a kind of usability easy for installation good rotary reducer.
The rotary reducer that the utility model provides, normally closed friction catch mechanism and planetary gear speed reducing mechanism are arranged in housing, housing comprises parts such as motor seat, cylinder body, friction bar, planetary wheel carrier bearing support and internal tooth housing, and wherein cylinder body, friction bar and planetary wheel carrier bearing support three parts are a part.
The rotary reducer that the utility model provides, under the prerequisite that satisfies the axis processing request with housing on a plurality of partial design become a part, reduced installation difficulty, reduced the use of Sealing, improve the installation soundness, improved anti-oil plant seepage property, also removed the manufacturing procedure of original each several part end face in the part that is linked to be one in addition from.As seen, the rotary reducer that the utility model provides has been saved processing cost and assembly cost, has improved usability.
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, its input part have with spring 4, have step and major diameter partly to point to the reducing piston block 3 of spring, having of cooperating with reducing piston block step reducing cylinder body, friction plate assembly 2 and friction bar constitute normally closed friction catch mechanism.Friction plate assembly and input shaft 1 are connected with spline pair, and spring is pressed between motor seat 5 and the piston block, has oil nozzle 7 connecting between piston block step and the cylinder body step through oil circuit on the cylinder body.Its output has with planet wheel 9, planetary wheel carrier, constitutes planetary gear speed reducing mechanism with the output shaft of planetary wheel carrier connection output gear 11, sun gear 10 and the internal tooth housing that is installed on the input shaft 1.Between normally closed friction catch mechanism and the planetary gear speed reducing mechanism planetary wheel carrier bearing support is arranged, planetary wheel carrier bearing support and the output gear axle bearing seat on the internal tooth housing are determined the stationary axle rotating center in the planetary gear speed reducing mechanism jointly.In said structure, the housing of whole rotary reducer is divided into three parts, and the one, motor seat 5, another is that the part that comprises cylinder body, friction bar, planetary wheel carrier bearing support three parts is braking casing 6, one is internal tooth housing 8 again.Have only two pairs of end faces that need sealing between motor seat and braking casing, braking casing and the internal tooth housing in the present embodiment, each then respectively seals two end axles with the axis hole on an outside framework oil seal and motor seat and the internal tooth housing.
Claims (1)
1, a kind of rotary reducer, normally closed friction catch mechanism and planetary gear speed reducing mechanism are arranged in housing, housing comprises parts such as motor seat, cylinder body, friction bar, planetary wheel carrier bearing support and internal tooth housing seat, it is characterized in that wherein cylinder body, friction bar and planetary wheel carrier bearing support three parts are a part.
