DETAILED DESCRIPTION
[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] This embodiment is a durable transmission housing for a micro-tiller.
[0028] like Figures 1-4 As shown, the transmission box 1 of the micro-tiller includes output shaft mounting holes 4 on the lower part of the outer surface of both sides of the transmission box 1. A sleeve 2 is provided at one end of the output shaft mounting hole 4, and there are two sets of sleeves 2. The two sets of sleeves 2 are fixedly installed on the lower part of the outer surface of both sides of the micro-tiller transmission box 1. The micro-tiller transmission box 1 includes an outer shell 5, a honeycomb perforated inner liner 6, an inner shell 7, noise reduction cotton 8, a support pad 9, a honeycomb perforated plate 10 and a honeycomb perforated folding plate 11. The outer shell 5 is located on the outermost side of the micro-tiller transmission box 1, and the honeycomb perforated inner liner 6 is located on the innermost side of the micro-tiller transmission box 1.
[0029] The honeycomb liner 6, honeycomb plate 10, and honeycomb folding plate 11 are all fixedly installed inside the inner shell 7; noise reduction cotton 8 is filled between the outer wall of the inner shell 7 and the inner wall of the outer shell 5; the support pad 9 passes through the noise reduction cotton 8 and is fixed between the inner wall of the outer shell 5 and the outer wall of the inner shell 7; the honeycomb folding plate 11 is fixedly installed between the inner wall of the honeycomb liner 6 and the outer wall of the honeycomb plate 10; an ear plate 3 is installed on the upper part of the outer surface of one side of the micro-tiller transmission box 1.
[0030] It should be noted that this utility model is a durable micro-tiller transmission housing. A sleeve 2 is installed at the output shaft mounting hole 4, which can increase the support points of the bearing, improve the stability of the bearing during transmission, and reduce wear and damage caused by vibration and shaking, thereby improving the durability of the micro-tiller transmission housing 1. The honeycomb perforated inner lining plate 6 is located on the innermost side of the micro-tiller transmission housing 1. The honeycomb perforated plate 10 and the honeycomb perforated folding plate 11, together with the honeycomb perforated plate 10, cause multiple reflections and refractions of sound waves during transmission. The sound waves interfere with each other inside, causing the sound waves to cancel each other out and effectively converting the sound wave energy into heat energy. This structure can reduce the generation and propagation of noise and reduce noise pollution. The noise reduction cotton 8 is filled between the outer wall of the inner shell 7 and the inner wall of the outer shell 5. The noise reduction cotton 8 can further reduce noise. The support pads 9 can increase the strength between the inner shell 7 and the outer shell 5.
