no. 1 example

[0045] see Figure 1-Figure 4 , the damping structure with transmission is applied to the top-mounted microwave oven with hot air convection function, and is used to drive the fan blade to rotate. It includes a transmission wheel 1, a transmission belt 2 and a driving wheel 3. The driving wheel 3 is connected to the motor output shaft and passes The belt 2 drives the transmission wheel 1, and the transmission wheel 1 is connected to the fan blades; in addition, it also includes a vibration damping block 4 set corresponding to the transmission belt 2, and the vibration absorption block 4 is provided with a contact surface 4.1, and the contact surface 4.1 and the transmission belt 2 Interval fit or direct contact with each other; when the interval fit between the contact surface 4.1 and the transmission belt 2, the gap is small and cannot be too large.

[0046] Furthermore, it also includes a bracket 5 fixedly arranged on the microwave oven, and the vibration-damping block 4 is ...

no. 2 example

[0053] see Figure 5 The shock absorbing structure of the belt drive in this embodiment differs from the first embodiment in that: the contact surface 4.1 is a plane, and the contact surface 4.1 of the plane is parallel to the transmission belt 2 .

[0054] Other parts not described are the same as those of the first embodiment, and will not be described in detail here.

no. 3 example

[0056] see Figure 6-Figure 8 , the damping structure with transmission of the present embodiment is different from the first embodiment in that: the damping block 4 is provided with a through hole 4.2, the bracket 5 is correspondingly provided with a screw hole 5.1, and the damping block 4 The bracket 5 is fixedly connected to each other through the screw 6; the through hole 4.2 is arranged in a circular shape, and the screw 6 passes through the through hole 4.2 and is screwed into the screw hole 5.1 to realize the fixed connection between the vibration damping block 4 and the bracket 5.

[0057] Other parts not described are the same as those of the first embodiment, and will not be described in detail here.

Abstract

A belt-transmission shock absorption structure comprises a transmission wheel, a transmission belt and a drive wheel. The drive wheel is connected with a motor output shaft and drives the transmission wheel through the transmission belt. The belt-transmission shock absorption structure further comprises a shock absorption block arranged corresponding to the transmission belt. A contact face is arranged on the shock absorption block, is matched with the transmission belt in a spaced manner, or makes direct contact with the transmission belt. When the contact face and the transmission belt are matched in the spaced manner, the gap is small and cannot be too large. The defects that a traditional structure is large in vibration and noise are effectively overcome through the shock absorption effect of the arranged shock absorption block on the transmission belt; and an existing transmission structure does not need to be changed, influences on functions of the transmission belt are small, the structure is simple and reasonable, application occasions are wide, installation and operation are flexible, the operation cost is low, space can be effectively saved, vibration of the transmission belt is rapidly and stably reduced, the low-noise requirement for household appliance products is met, and the user experience is improved. It can be seen that the belt-transmission shock absorption structure has the beneficial effects of being simple and reasonable in structure, reliable in performance, high in adaptability, easy to operate and low in cost.

Description

technical field [0001] The invention relates to a belt drive structure, in particular to a belt drive damping structure, which is specifically applied to household electrical appliances. Background technique [0002] Belt transmission is often used in household appliances due to its simple and convenient structure, easy replacement, and safety. For example, the common top-mounted microwave ovens with hot air convection function on the market use a belt drive to provide power for the hot fan blades. For the convenience of assembly, highly elastic round rubber belts are often used for belt drives, but rubber belts are prone to large vibrations and slapping adjacent parts, resulting in loud noises, which greatly affect the customer's product experience. [0003] The vibration source of the belt is complex, and the reasons for the vibration are as follows: 1. Due to the technical level and cost requirements, the errors in the manufacture and assembly of the transmission wheel c...
