Abstract
The utility model discloses an effectual belt pulley of sediment outflow, its characterized in that: including big flywheel, the ring gear has on the outer circumference of big flywheel, the both sides of ring gear all have the band pulley retaining ring, the equipartition has a plurality of sand discharge openings on the band pulley retaining ring circumference, sand discharge opening's mouth is followed and is located the tooth root of ring gear is inboard, makes sand discharge opening department the ring gear exposes the tooth root. The beneficial effects of the utility model include: firstly, the belt wheel retainer rings are arranged on two sides to ensure that the deviation angle of the belt at 1-3 ℃ can be adjusted in the large and small flying motion process. And secondly, belt wheel check rings are installed on two sides to effectively prevent the sand from entering. Thirdly, a sand discharge opening with the thickness of 5 mm-10 mm is added on the retainer ring, so that the sand entering the moving friction part of the chain wheel belt is effectively discharged.
Description
Technical Field
The utility model relates to a motorcycle transmission system field, concretely relates to effectual belt pulley of sand discharging.
Background
Put motor electric motorcycle car in tradition and adopt belt pulley transmission more, the belt pulley adopts both sides installation retaining ring to prevent silt and carry out certain spacing to the belt at the operation in-process more, but its discharge effect after advancing silt is not good, influences belt life.
Disclosure of Invention
To the weak point among the above-mentioned prior art, the utility model provides an effectual belt pulley of sediment outflow, it can satisfy the spacing of belt, has good sediment outflow effect simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an effectual belt pulley of sand discharging which characterized in that: including big flywheel, the ring gear has on the outer circumference of big flywheel, the both sides of ring gear all have the band pulley retaining ring, the equipartition has a plurality of sand discharge openings on the band pulley retaining ring circumference, sand discharge opening's mouth is followed and is located the tooth root of ring gear is inboard, makes sand discharge opening department the ring gear exposes the tooth root.
Furthermore, a plurality of sand discharge openings positioned on two sides of the gear ring are arranged in a manner that two sides are opposite or two sides are staggered.
Further, the tooth form of the gear ring is straight cylindrical teeth.
Furthermore, a plurality of mounting holes are distributed in the middle of the large flywheel.
The beneficial effects of the utility model include: firstly, the belt wheel retainer rings are arranged on two sides to ensure that the deviation angle of the belt at 1-3 ℃ can be adjusted in the large and small flying motion process. And secondly, belt wheel check rings are installed on two sides to effectively prevent the sand from entering. Thirdly, a sand discharge opening with the thickness of 5 mm-10 mm is added on the retainer ring, so that the sand entering the moving friction part of the chain wheel belt is effectively discharged.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
The utility model provides a belt pulley that sand discharge effect is good as shown in figure 1, includes big flywheel 1, ring gear 2 has on the outer circumference of big flywheel 1, big flywheel 1 and ring gear 2 integrated into one piece, ring gear 2's both sides all have band pulley retaining ring 3, band pulley retaining ring 3 with ring gear 2's both sides terminal surface links firmly. The equipartition has a plurality of sand discharge openings 4 on 3 circumferences of band pulley retaining ring, sand discharge opening 4's mouth is followed and is located gear ring 2's tooth root is inboard, makes sand discharge opening 4 department gear ring 2 exposes the tooth root, and the silt that conveniently gets into the gear ring is discharged from sand discharge opening.
In some embodiments of the utility model, the sand discharge ports 4 on both sides of the gear ring 2 are arranged in a manner of being opposite to each other on both sides, so that the sand discharge effect is good; in another embodiment, the sand discharge openings 4 on two sides of the gear ring 2 are arranged in a staggered mode on two sides, so that the belt is better in guiding effect, and the situation that the belt jumps out of the gear ring is avoided.
In the embodiment, the tooth form of the gear ring 2 is straight cylindrical teeth, so that transmission is more stable, and the belt is prevented from slipping.
Furthermore, a plurality of mounting holes are distributed in the middle of the large flywheel 1 and used for mounting the large flywheel 1 on a rear wheel hub of the motorcycle.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
