Description

Technical Field

[0001] This utility model belongs to the technical field of gear noise reduction, specifically relating to a low-noise modified gear that produces noise levels no higher than 80 decibels when a stirrer is in operation. Background Technology

[0002] Currently, mixers are commonly used for kneading dough. However, the noise level of mixers on the market is generally around 100 decibels, with some even reaching 120 decibels or higher. Research has found that mixers typically use eccentric gear sets to transmit power, and the noise is mainly generated by these gear sets. Currently, users generally complain that the noise from mixers is too high, causing annoyance and resulting in a poor user experience. Therefore, there is an urgent need to solve the problem of reducing the excessive noise generated by the gear sets during operation.

[0003] To address this, we developed a low-noise modified gear that operates with a noise level not exceeding 80 decibels. Summary of the Invention

[0004] The purpose of this invention is to provide a low-noise modified gear for a stirrer that operates with a noise level not exceeding 80 decibels.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bass-modified gear, comprising a gear body; teeth are evenly distributed on the outer circumference of the gear body; each tooth has a horizontal tooth direction line that is symmetrically distributed in an arc shape, and the tooth direction line protrudes outward by 0.02-0.03 mm at its highest point.

[0006] Preferably, the tooth line is elliptical, being a portion of its corresponding ellipse.

[0007] Preferably, the toothed line is circular, being a portion of its corresponding circle.

[0008] Compared with the prior art, this utility model provides a bass-modified gear, which has the following beneficial effects:

[0009] The horizontal tooth profile of each tooth of the bass-modified gear described in this utility model is symmetrically distributed in an arc shape, and the tooth profile protrudes outward by 0.02-0.03 mm at its highest point. After testing, the noise level is 75 decibels at low speed, 80 decibels at medium speed, and 85 decibels at high speed. The test results are very ideal and can meet the design requirements.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-2 This utility model provides a technical solution: a bass-modified gear, including a gear body 1; teeth 2 are evenly distributed on the outer circumference of the gear body 1; each tooth 2 has a horizontal tooth direction line 21 that is symmetrically distributed in an arc shape, and the tooth direction line 21 protrudes outward by 0.02-0.03 mm at its highest point.

[0016] In this embodiment, the tooth line 21 is elliptical, being a part of its corresponding ellipse; of course, it can also be configured such that the tooth line 21 is circular, being a part of its corresponding circle.

[0017] When applied to a mixer, the noise level was 75 decibels at low speed, 80 decibels at medium speed, and 85 decibels at high speed. Under normal circumstances, 60 decibels is considered a very quiet environment during the day, while 80 decibels is considered slight noise. The test results are very satisfactory and meet the design requirements.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The horizontal tooth 2 of each tooth 2 of the bass profile gear of this utility model is symmetrically distributed in an arc shape, and the tooth 21 protrudes outward by 0.02-0.03 mm at its highest point. After testing, the noise level is 75 decibels at low speed, 80 decibels at medium speed, and 85 decibels at high speed. The test results are very ideal and can meet the design requirements.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
