Planet speed reduction driving mechanism

Abstract

The invention relates to a planet speed reduction driving mechanism, which comprises a pneumatic clutch, a planet speed reducer, a drive gear box and a plurality of transmission gears, wherein the pneumatic clutch is arranged on a power input shaft of the planet speed reducer; an output shaft of the planet speed reducer is directly inserted in a combination hole behind the drive gear box, and a mounting flange on the output shaft is connected and fixed with the rear end face of the combination hole by a bolt; a driving gear in the transmission gears is arranged on the output shaft of the planet speed reducer; a driven gear in the transmission gears is arranged on an upper right mud-pressing shaft and is meshed with the driving gear; a counter gear in the transmission shaft are arranged with the driven shaft on the same step coaxially and is horizontally meshed with a counter gear arranged on an upper left mud-pressing shaft; and an extrusion shaft is directly inserted in an inner hole of the output shaft of the planet speed reducer and is fixed with the inner hole by a tension cone sleeve for power transmission. The planet speed reduction driving mechanism adopts a straight-tooth cylindrical gear set to drive the two mud-pressing shafts, the straight-tooth cylindrical gear set is operated harmoniously with the extrusion shaft, the driving gear is directly arranged on the output shaft of the speed reducer, the driven gear and the counter gears are arranged at two mud-pressing shaft ends, and three sets of shaft couplings are saved, so the transmission efficiency and the transmission accuracy are improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission devices, in particular to a deceleration transmission mechanism for large vacuum extruders in the field of brick and tile machinery manufacturing. Background technique [0002] With the deepening of the reform of wall materials in our country, the brick and tile industry has begun to develop towards large-scale, intensified and automated aspects. New requirements have become the primary issue facing the brick and tile machinery manufacturing industry. It is true that in recent years, brick and tile equipment manufacturing enterprises have invested a lot of effort and sweat to provide the industry with many new models with large specifications and high pressure. However, compared with similar foreign products in terms of their comprehensive technical level, there is still a large gap, especially It is an extruder used in the brick and tile forming process. No matter its volume, wei...

Problems solved by technology

The reason: In addition to factors such as metal materials, production equipment and processing methods, there are obvious differences in the design and configuration of the reduction transmission mechanism. The intuitive manifestations are: First, the configuration of the reducer is backward, and most manufacturers still use The traditional ZQ series reducer is used, but with the transformation of industrial policies, brick-making raw materials (change from high plastic clay to hard plastic extrusion) and product performance (thin-walled high-strength, high-cavity, self-insulation), the extruder’s The specifications, models and power are getting bigger and bigger, which makes the model of the reducer bigger and bigger, so that there is no match

Second, large-scale ZQ series reducers are large in size, heavy in weight, small in speed ratio, and low in efficiency. For example, a 60-type hard plastic vacuum extruder with a power greater than 250KW needs to be equipped with a 130-type reducer. The weight of the reducer itself is 7500kg, the volume (length, width, height) is 2500×1100×1526 (mm), and the average market price is 150,000 yuan. Its weight, volume and price all account for 1 / 3 of the entire extruder, resulting in extrusion The production cost of the machine is rising

The third is that the ZQ series reducer is a general-purpose product for the society, not specially designed for the extruder of brick and tile forming. more improved
