Abstract
The utility model discloses a suspension gear set, which comprises a fixed disk and an outer gear, wherein a shaft hole connected with a main shaft is arranged in the center of the fixed disk; the outer gear is sleeved on the fixed disk; a boss is arranged on the contacted surface of the fixed disk and the outer gear; a concave hole is arranged on the contacted surface corresponding to the outer gear; a concave hole seat of the outer gear is connected with the boss of the fixed disk; and a buffer sleeve is arranged between the concave hole of the outer gear and the boss of the fixed disk. The utility model has the advantages of simple structure and favorable buffer.
Description
Technical field
The utility model relates to a kind of shock-absorbing gear train, specifically belongs to the shock-absorbing gear train that is installed on the rotor main shaft.
Background technique
Different gear trains can be installed on the main shaft of existing rotor and cooperate the motor reducer gear train, what of the number of gears are the speed of Zhuan Bianing be provided with as required, or realize speed change by a plurality of Gear combination.The structure of general gear train is established single gear, is provided with an axis hole in the gear in order to connect the axis hole of main shaft.Rotor all is with rigid motion, and when stopping suddenly at the volley or during reverse rotation, reverse torsion can appear in rotor.Rotor cogs and can produce the rigidity friction with the gear of motor reducer, causes noise and gear to damage easily or wear and tear to add certificate.
The model utility content
The purpose of this utility model is to address the aforementioned drawbacks, and a kind of simple in structure, a kind of shock-absorbing gear train with comfort cushioning effect is provided.
For achieving the above object:
A kind of shock-absorbing gear train, comprise fixed tray and external gear, fixed tray central authorities have the axis hole that connects main shaft, on the external gear fit fixed tray, the surface of contact of described fixed tray and external gear is provided with projection, the surface of contact of external gear correspondence is provided with shrinkage pool, and the concave hole base of external gear connects on the projection of fixed tray, also is provided with a cushion collar between the shrinkage pool of external gear and the projection of fixed tray.
Described fixed tray is provided with plural projection, and projection is evenly distributed on the surface of contact of fixed tray, and the shrinkage pool setting of external gear is corresponding with projection.
Described cushion collar is the plastics gum cover.
The beneficial effects of the utility model:
Be provided with a cushion collar between the projection of fixed tray of the present utility model and the shrinkage pool of external gear.Can avoid rotor to stop suddenly at the volley like this or during reverse rotation rotor cog and can produce the rigidity friction with the gear of motor reducer, cause noise and gear to damage easily or wearing and tearing add certificate.Cushion collar can effectively alleviate the rigidity friction between external gear and the fixed tray as a kind of flexible media between projection and the shrinkage pool, and the life-span of product must only need be made regular check on or the exchange buffering cover in prolongation, and the reduction maintenance cost is arranged like this.
