Description
Technical field
The utility model relates to a kind of retarding starter, relates in particular to a kind of starter slowing-down mechanism of tool pooling feature.
Background technique
The starter motor that gear reducer is housed between the armature shaft of starter motor and actuation gear, is called retarding starter.The power of series excitation type direct current motor is directly proportional to its torque and rotational speed, visible, reduce its torque in the time improving motor speed time, can keep starter motor power constant, therefore when adopting the series excitation type direct current motor of high speed, low torque as starter motor, in the situation that power is identical, can make the volume of starter motor and quality greatly reduce.But the torque of starter motor is too low, can not meet the requirement of piloting engine., adopt at a high speed, when the direct current motor of low torque in starter motor, mounting teeth wheel decelerator between the armature shaft of motor and actuation gear can improve its torque in reducing motor speed for this reason.
The reduction gears mechanism of retarding starter has three kinds of outer gearing formula, interior engagement type, planetary gear types etc. multi-form, at present, general planetary gear type starter motor, generally comprise a direct current generator and planetary reducer, planetary gear ring is directly fixed on the shell of starter motor, and the torque that motor produces is passed to coaxial one-way element by armature shaft gear, planetary pinion.Because the motor torque of starter motor is directly exported by coaxial one-way element, when the moment of starter motor and motor engagement, the impact endurance test shock of generation is larger, very easily causes the damage of reduction gears mechanism and other component, and reliability is poor.
Model utility content
The purpose of this utility model is to provide a kind of starter slowing-down mechanism of tool pooling feature, its impact endurance test shock that can make starter motor produce in the time starting is effectively contained, to solve the larger problem of impact endurance test shock existing when retarding starter in prior art starts.
For reaching this object, the utility model by the following technical solutions:
A kind of starter slowing-down mechanism of tool pooling feature, it comprises housing and planetary gear reducing mechanism, the center of described housing offers endoporus, described planetary gear reducing mechanism comprises external toothing, planetary pinion and planet axis, described external toothing is arranged in housing, described planetary pinion is arranged in external toothing, described planet axis is through endoporus, wherein, on the inwall of described housing, offer several holding cavities, in described holding cavity, be provided with cushion pad, described cushion pad is fixedly connected with described external toothing.
Especially, be provided with the attachment post of corresponding holding cavity number in the outer rim of described external toothing, the post that is connected is offered porose on described cushion pad, in described attachment post patchhole, external toothing is fixedly connected with cushion pad.
Especially, described housing, for being arranged between starter front cover and stator assembly independently assembling shell, is provided with first and second step surface in described housing, and described external toothing is assemblied on First terrace, between described second step face and planet axis, bearing is installed.
Especially, the number that arranges of described holding cavity is four, and it is distributed on the inwall of described housing.
Especially, described cushion pad is rubber buffer.
The beneficial effects of the utility model are; compared with prior art the starter slowing-down mechanism of described tool pooling feature is provided with several cushion pads being fixedly connected with the external toothing of planetary gear reducing mechanism on the inwall of housing; the impact endurance test shock producing when effectively starter motor startup by cushion pad is contained; protect not being damaged of planetary gear reducing mechanism and other component, thereby ensured the reliability of starter motor entirety.
