Abstract
The utility model discloses a noise reduction sprocket wheel which comprises a wheel body. Uniformly distributed wheel teeth are arranged on the wheel body. A radial extending part is arranged on the wheel body and connected with the wheel teeth. Sound insulation layers are arranged on two sides of the extending part, limit check rings are arranged on two sides of the sound insulation layers, and the sound insulation layers are made of ethylene-propylene-diene monomer (EPDM) rubber. The limit check rings are in interference fit with the wheel body. The width of the sound insulation layers and the width of the limit check rings correspond to the width of the extending part. According to the noise reduction sprocket wheel, noise of the sprocket wheel can be effectively reduced, sound insulation is achieved through the sound insulation layers when the sprocket wheel operates, noise of work environment is greatly reduced, and using effects are good in actual working conditions. At the same time, the sound insulation layers and the limit check rings are arranged on two sides of the extending part, so normal working of the wheel teeth is ensured.
Description
Technical field
The utility model relates to a kind of mechanically operated sprocket wheel.
Background technique
Sprocket wheel is the wheel with the cog type whelp, in order to pitch chain ring or cable on pitch accurately block be meshed or for solid or with the gear of spoke, mesh to transmit motion with (roller) chain, be widely used in the mechanical transmission of the industries such as chemical industry, textile manufacturing machine, food processing, instrument, oil etc.
The model utility content
The purpose of this utility model is to provide a kind of noise-reduction sprocket wheel that can effectively reduce noise.
A kind of noise-reduction sprocket wheel comprises wheel body, and wheel body is provided with the equally distributed gear teeth, it is characterized in that: wheel body is provided with extension part radially, and extension part connects the gear teeth, and the both sides of extension part are provided with puigging, and the both sides of puigging are provided with spacing back-up ring.
Preferably, puigging is made by EPDM rubber.
Further, interference fit between spacing back-up ring and the wheel body.
Further, all the width with extension part is corresponding for the width of puigging, spacing back-up ring.
The utility model has following beneficial effect owing to adopted technique scheme:
Can effectively reduce the noise of sprocket wheel, sprocket wheel carries out sound insulation by puigging when work, greatly reduce the noise of working environment, and using effect is better in actual conditions; Puigging and spacing back-up ring are arranged on the both sides of extension part simultaneously, guarantee the normal operation of the gear teeth.The utility model is simple and reliable for structure, manufacturing is easy, cost is low, and is practical.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of a kind of noise-reduction sprocket wheel of the utility model.
Embodiment
As shown in Figure 1, be a kind of noise-reduction sprocket wheel of the utility model, comprise wheel body 1, wheel body 1 is provided with the equally distributed gear teeth 2, wheel body 1 is provided with extension part 3 radially, extension part 3 connects the gear teeth 2, the both sides of extension part 3 are provided with puigging 4, puigging 4 is made by EPDM rubber, the both sides of puigging 4 are provided with spacing back-up ring 5, interference fit between spacing back-up ring 5 and the wheel body 1, and assurance puigging 4 reliably is fixedly connected with joint, the width of puigging 4, the spacing back-up ring 5 all width with extension part 3 is corresponding, guarantees the normal operation of the gear teeth 2.The utility model can effectively reduce the noise of sprocket wheel, and sprocket wheel carries out sound insulation by puigging 4 when work, greatly reduce the noise of working environment, and using effect is better in actual conditions; Puigging 4 and spacing back-up ring 5 are arranged on the both sides of extension part 3 simultaneously, guarantee the normal operation of the gear teeth 2.
Only be specific embodiment of the utility model below, but technical characteristics of the present utility model is not limited to this.Any take the utility model as the basis, for realizing essentially identical technique effect, done the ground simple change, be equal to replacement or modification etc., all be covered by among the protection domain of the present utility model.
