Abstract
The invention relates to a vibration damping frame structure, applied to a planet reducing gear. The vibration damping frame structure comprises a planet gear and a vibration damping frame body; wherein the planet gear is arranged in the vibration damping frame body, the external part of the planet gear is held up by a rubber sleeve, the two sides of the rubber sleeve are coated at the external party of the planet gear, the rubber sleeve is contacted with the inner wall of the vibration damping frame body and the rubber sleeve is uniformly coated on the side wall of the planet gear, thus promoting the planet gear to achieve self centering. The planet reducing mechanism of the invention adopts a floating ring gear to realize self centering, the ring gear is held up by the rubber sleeve and is connected with the vibration damping frame, when the planet reducing gear outputs power, self centering can be realized as the ring gear has a certain floating space, and impact force can be absorbed and vibration and noise can be reduced as the connection of the rubber sleeve is not rigid. Impact force is absorbed, vibration and noise are reduced, processing difficulty is lowered and cost is reduced.
Description
Technical field
The present invention relates to a kind of planetary pinion damping shelf structure.
Background technique
The starter motor planetary gear speed reducing mechanism is to be driving gear by the armature shaft gear, drives planetary pinion planet carrier and ring gear, forms a cover reducing gear outputting power, general planetary gear speed reducing mechanism is that ring gear is fixed, requirement machining accuracy height, difficulty of processing is big, and cost is also high.
Summary of the invention
The purpose of this invention is to provide a kind of vibration damping frame structure, solve the planetary speed reducer gear structure and in operation process, have the problem of vibrating noise.
The objective of the invention is to be achieved through the following technical solutions:
Vibration damping frame structure, be applied on the planetary gear speed reducing mechanism, comprise planetary pinion and dynamic mount body, described planetary pinion is installed in the dynamic mount body, hold by rubber sleeve described planetary outside, and described rubber sleeve is that bilateral is coated on planetary outside, contacts by the inwall of rubber sleeve with the dynamic mount body, and rubber sleeve covers the sidewall of planet tooth uniformly, can promote that so also planetary pinion reaches self contering.
The described planetary gear speed reducing mechanism of this patent is to adopt the ring gear self contering of floating, ring gear is held with dynamic mount by rubber sleeve and is connected, planetary gear speed reducing mechanism is when outputting power, because ring gear has certain floating space, can self contering, because the connection of rubber sleeve is not a rigidity, can absorb impact force, reduce vibration and noise.Absorb impact force, reduce vibration and noise, reduce difficulty of processing, reduce cost.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the sectional structure chart of planetary pinion damping shelf structure dynamic mount body.
Fig. 2 is the front view of dynamic mount body;
Fig. 3 is planetary sectional structure chart;
Fig. 4 is planetary front view;
Fig. 5 is the sectional structure chart of rubber sleeve;
Fig. 6 is the front view of rubber sleeve.
Embodiment
Shown in Fig. 1-6, vibration damping frame structure, be applied on the planetary gear speed reducing mechanism, comprise planetary pinion 1 and dynamic mount body 2, described planetary pinion 1 is installed in the dynamic mount body 2, and hold by rubber sleeve 3 outside of described planetary pinion 1, described rubber sleeve 3 is coated on the outside of planetary pinion 1 for bilateral, contact by the inwall of rubber sleeve 3, and rubber sleeve 3 covers the sidewall of planet tooth 1 uniformly, so also can promote planetary pinion 1 to reach self contering with dynamic mount body 2.
The described planetary gear speed reducing mechanism of this patent is to adopt the ring gear self contering of floating, ring gear is held with dynamic mount by rubber sleeve and is connected, planetary gear speed reducing mechanism is when outputting power, because ring gear has certain floating space, can self contering, because the connection of rubber sleeve is not a rigidity, can absorb impact force, reduce vibration and noise.Absorb impact force, reduce vibration and noise, reduce difficulty of processing, reduce cost.
