Planetary reducer applied to ring rolling mill

Abstract

The invention discloses a planetary reducer applied to a ring rolling mill. The planetary reducer comprises an input bevel gear shaft, a bevel gear, a crowned gear shaft, a connecting inner gear sleeve, a sun gear, a planet gear, an inner gear ring, a planet carrier and a machine body, the input bevel gear shaft is installed on a bearing sleeve through a sliding bearing, the bearing sleeve is installed on the machine body, the bevel gear is fixed to the crowned gear shaft through a key, the two ends of the crowned gear shaft are installed on a lower support and the machine body through bearings, the sun gear and the crowned gear shaft are connected through the connecting inner gear sleeve, the planet gear is installed on the planet carrier through the bearing and the planet gear shaft, the inner gear ring is fixed to the machine body through a pin, the planet carrier is installed on the upper support through the bearing, and the planetary reducer of the ring rolling machine is integrally formed; power is transmitted to the sun gear from the input bevel gear shaft through the bevel gear and the crowned gear shaft, then transmitted to the planet gear from the sun gear and then transmitted to the planet carrier from the planet gear, and power output is achieved. The planetary reducer applied to the ring rolling mill is reasonable in structure, relatively low in cost, convenient to install, use and maintain, reliable in performance and low in investment.

Description

Technical field [0001] The present invention belongs to the mechanical field, in particular to a ring rolling machine is applied to planetary gear. Background technique [0002] Ring rolling machine for rolling ring main type parts, compared with ordinary forging, rolling significantly improved efficiency and accuracy, it is widely used in the ring rolling machine manufacturing industry; With the development of science and technology and the technology advances, diameter 10 ring needs more meters or more, such as wind power industry, existing equipment is difficult to meet market demand; currently, main gear structure ring rolling machine domestic use such as figure 1 , 2 Shown, a plus two bevel gear spur gear, heavy weight, large power ring rolling machine often more than 100 tons, complex structure, difficult processing, high cost, long processing cycle, gradually revealed drawbacks for many years, been to replacement stage. Inventive content [0003] Object of the present inv...

Problems solved by technology

[0002] The ring rolling machine is mainly used for rolling ring parts. Compared with ordinary forging, the rolling efficiency and precision are significantly improved, so the ring rolling machine is widely used in the machinery manufacturing industry; with the development of technology and technological progress, the diameter of 10 There are more and more demands for rings over 100 meters, such as the wind power industry, the existing equipment is difficult to meet the market demand; at present, the structure of the main reducer of the ring rolling machine adopted in China is as follows: figure 1 , 2 As shown, one-stage bevel gear plus two-stage cylindrical gear, the weight is heavy, and the ring rolling machine with high power often exceeds 100 tons.
