Description

Energy-saving reducer for conveyer

Technical field

The utility model belongs to mechanical equipment, particularly a kind of energy-saving reducer for conveyer.

Background technology

Industries such as mine, chemical industry, harbour widely apply belt conveyer and slat conveyer as efficient, continuous conveying mechanical, and reductor is the main corollary equipment of above-mentioned main frame.The matched reductor of current main frame mostly is common involute spur gear, helical wheel and the transmission of common involute tapered tooth spiral arc bevel gear, and the type of cooling is natural air cooled substantially, so just causes bulky self the wasted work energy consumption height of reductor, noise big.Along with commercial production towards high-yield and high-efficiency, high-power, intensification, intelligent direction development, the power of reductor is continuing to increase, energy consumption and noise also increase naturally, the reductor of existing structure form has been difficult to satisfy such demand.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides that a kind of energy consumption is low, noise is little, the energy-saving reducer for conveyer that operates steadily.

The technical scheme that the utility model technical solution problem adopts is: energy-saving reducer for conveyer comprises casing, drive bevel gear axle, pinion shaft, pinion shaft gear, Large Gear Shaft During, Large Gear Shaft During gear, big gear wheel, macro-axis, big shaft gear, be characterized in being fixed with drive bevel gear on the drive bevel gear axle, key connects the suit driven wheel of differential on the pinion shaft, drive bevel gear and driven wheel of differential are prolate epicycloid arc awl equal-depth teeth or accurate hyperbolic bank awl equal-depth teeth, are connected by meshing transmission between drive bevel gear and the driven wheel of differential.

The beneficial effects of the utility model are: energy-saving reducer for conveyer first order gear pair adopts prolate epicycloid arc awl equal-depth teeth or accurate hyperbolic bank awl equal-depth teeth engaged transmission, changed gear pair engagement effect, overlap coefficient and load-carrying capacity have been increased, compare with general reductor, power consumption has reduced by 1/5, volume-diminished 1/3, weight saving 1/3, running life prolongs 2 times, and operating cost significantly reduces.Owing to improved engagement, improved working accuracy simultaneously, noise also significantly reduces, and has improved the environmental protection noise of operation range, has ensured post workman's physical and mental health.
