Abstract
The utility model discloses a chain wheel which comprises a chain wheel body. The chain wheel body is composed of an installation hole, a gear tooth ring and spoke plates, wherein the installation hole and the gear tooth ring is connected through the spoke plates, and lightening holes are arranged in the spoke plates, so the weight of the chain wheel is reduced. The chain wheel is simple in structure, convenient to carry and capable of reducing energy consumption when the chain wheel works in a transmission system.
Description
Technical field
The utility model relates to a kind of sprocket wheel.
Background technique
Sprocket wheel is a kind of toothed wheel shape mechanical parts that are meshed with chain, and sprocket wheel all is Integral chain wheel in the prior art, and is heavy for larger-diameter sprocket wheel, both has been unfavorable for carrying, and increased the energy consumption of whole transmission system.
The model utility content
Technical problem to be solved in the utility model provides the lighter sprocket wheel of a kind of weight.
For achieving the above object, the utility model provides following technological scheme: a kind of sprocket wheel comprises sprocket body, and described sprocket body is comprised of the disc of mounting hole, wheel gear ring and connection hole and wheel gear ring, and described disc is provided with lightening hole.
Preferably, described lightening hole runs through disc, is circumference at disc and equidistantly distributes.
Preferably, described disc is provided with the stiffening rib of connection hole and wheel gear ring.
Preferably, described stiffening rib is positioned at the lightening hole both sides.
Adopt the beneficial effect of above technological scheme to be: sprocket wheel adopts the plate spoke structure, be provided with the stiffening rib of connection hole and wheel gear ring at disc, guaranteed the intensity of whole sprocket wheel, disc is provided with several lightening holes, alleviated the weight of sprocket wheel, convenient carrying in the work of transmission system, has reduced energy consumption.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1-mounting hole, 2-wheel gear ring, 3-disc, 4-lightening hole, 5-stiffening rib.
Embodiment
Describe preferred implementation of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 has shown the mode of execution of a kind of sprocket wheel of the utility model: this sprocket wheel comprises sprocket body, disc 3 by mounting hole 1, wheel gear ring 2 and connection hole 1 and wheel gear ring 2 forms, disc 3 is provided with lightening hole 4, this lightening hole 4 runs through disc 3, being circumference at disc 3 equidistantly distributes, be provided with connection hole 1 and the stiffening rib 5 of taking turns gear ring 2 at disc 3, stiffening rib 5 is positioned at lightening hole 4 both sides.
Adopt the beneficial effect of above technological scheme to be: use the sprocket wheel of this structure, alleviated the weight of sprocket wheel, convenient carrying in the work of transmission system, has reduced energy consumption.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
