Variable-speed box of rubber-roller sheller

Abstract

A variable speed gear of rubber-roller rice huller comprises an input wheel which is fixed on the input end of a rubber roller main shaft 3 and is connected with the output wheel of a power unit through a driving belt 2.The invention is characterized in that: the input wheel adopts a tower type hierarchical structure, that is, the input wheel consists of two or more than two driving wheels 5, 6 with different diameters, the driving wheels 5, 6 of the input wheels of two rubber rollers match in a same group, and the driving wheels 5, 6 belonging to the same group are respectively connected with the output wheel of the power unit through the driving belt 2. The output wheel of the variable speed gear of rubber-roller rice huller provided by the invention can match with driving mechanisms of different level groups to adjust the linear speed of the rubber rollers with short time, little workload, simple operation, low maintenance cost as well as capability of not increasing noise during movement.

Description

Technical field [0001] The invention relates to a speed change device of a rubber roller huller. Background technique [0002] In the prior art, the rubber roller husker speed change device has a structure such as figure 1 As shown, the input wheel 1 is included, and the input wheel 1 is fixed on the input end of the rubber roller main shaft 3, and the input wheel 1 is connected with the output wheel of the power device through the transmission belt 2. The above-mentioned husker adjusts the linear speed of the rubber rollers by exchanging the rubber rollers, which requires a long time and a large workload to adjust the rubber rollers. For this reason, there is also a gearbox to adjust the speed of the rubber roller. Although it is very simple to adjust the speed of the rubber roller in this way, it adds a moving part, that is, the gearbox. Because the gearbox is prone to oil leakage, it is not environmentally friendly, the noise is loud during movement, the failure rate in...

Problems solved by technology

Although it is very simple to adjust the speed of the rubber roller in this way, it adds a moving part, that is, the gearbox. Because the gearbox is prone to oil leakage, it is not environmentally friendly, the noise is loud during movement, the failure rate increases, and frequent maintenance is required, which increases the cost of use.
