Abstract
The utility model discloses a large idle gear structure which comprises a gear disc. An installation sleeve is arranged in the center of the wheel disc, a rubber sheath is arranged in the installation sleeve, a plurality of long grooves are formed along the radial direction from the inner wall of the installation sleeve to the internal of the installation sleeve, and an elastic strip is arranged in every long groove. The large idle gear structure has the advantages of being simple in structure, easy to realize, capable of maintaining the rubber sheath and a gear shaft in a tight matching state and improving the operation stability of gears.
Description
Technical field
The utility model relates to field of gears, is specially a kind of large idle gear structure.
Background technique
Motor is a kind of power generating apparatus, and its effect is can be converted into mechanical energy with other forms of.Commonly use in the motor and transmit motion state to large idle gear, large idle gear effect only is the direction of changing motion, does not contribute velocity ratio.After the large idle gear of prior art service time is long, is combined with gear shaft and is prone to the not problem of close-fitting, affect the normal operation of gear.
The model utility content
The utility model purpose provides a kind of large idle gear structure, is combined the not problem of close-fitting that is prone to gear shaft to solve the large idle gear of prior art.
In order to achieve the above object, the technological scheme that adopts of the utility model is:
A kind of large idle gear structure, include wheel disc, wheel disc dish edge forms a plurality of gear teeth, have a plurality of lightening holes that distribute along even circumferential on the wheel disc, it is characterized in that: the described disk center of taking turns is provided with installing sleeve, and the cylinder end of installing sleeve exceeds respectively the wheel disc card, is close to the installing sleeve inwall in the installing sleeve and is provided with rubber sheath, radially to installing sleeve, have the multiple tracks elongated slot from the installing sleeve inwall, be respectively arranged with the elastic strip that is pressed on the rubber sheath in the per pass elongated slot.
Described a kind of large idle gear structure, it is characterized in that: described elongated slot has four roads, is distributed in the installing sleeve along even circumferential.
The utility model is simple in structure, is easy to realize, utilizes elastic strip radially exerting pressure to rubber sheath, makes rubber sheath keep the close-fitting state with gear shaft, has improved gear operation stability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
