Description
Technical field
The utility model belongs to agricultural harvesting machinery component technology field, relates to the speed reducer of wheat, three row corn combine tool running gears, refers in particular to closed internal messing limit and subtract case.
Background technique
China is large agricultural country, in recent years, combine-harvester industry had obtained very large development, and all kinds of combined harvester production quantity hits new peak repeatly, become the field of most active, the richest vigor in agro-based industry, be classified as the machinery industry of preferential encourage growth by country.The rim decelerating mechanism that existing wheat, three row corn machine combined harvesters use is semi-enclosed structure, bearing and gear are in packing less space, cannot lubricating oil filling, can only be grease-added, because space is not airtight, use working condition poor, in use lubricating grease can bond dust, oxidation become dry, as filling not in time can cause wearing and tearing aggravation even to damage after lubricating grease lost efficacy, be load high product performance, and be improved to the closed limit of internal messing and subtract box assembly.
Summary of the invention
In order to overcome defect of the prior art, the utility model is based on the requirement improving product reliability, under requiring driving system input shaft and output shaft to turn to identical prerequisite, by the rational modification of structural type, greatly improve the performance of product, complete machine is highly improved in operational safety, and spy provides a kind of closed internal messing limit to subtract case.
The purpose of this utility model is achieved in that closed internal messing limit subtracts case, comprise integrated type casing, be provided with the input gear axle and output flange axle that are parallel to each other by bearing in casing, output flange axle is provided with bull gear, and input gear axle and bull gear form internal gear pair; Casing is provided with blanking cover after case lid and flange shaft, blanking cover and its composition enclosed construction after case lid, flange shaft.
Above-mentioned bearing is arranged on bearing support, together with the bearing support of input gear axle is directly cast with casing.
Above-mentioned bull gear is positioned at casing.
The input end of above-mentioned input gear axle and the output terminal of output flange axle are all positioned at outside casing.
Above-mentioned input gear axle, between output flange axle and casing, be provided with oil sealing.
Above-mentioned casing is provided with drain oil and vent.
The utility model gives prominence to compared to existing technology and useful technique effect is:
1, the utility model is enclosed construction, blanking cover composition seal space after integrated type casing and case lid, flange shaft, input gear axle and the ring gear be arranged on output flange axle form internal gear pair, make input and output rotating in same direction, during use annotate liquid lubricant, bearing and gear lubrication good, good reliability, long service life, after complete machine, can significantly improve the reliability of complete machine;
2, together with the bearing support of the utility model input gear axle is directly cast with casing, compact structure, intensity is high, good rigidly, and precision is high, and input and output are internal messing, meets input and output sense of rotation identical with original mechanism sense of rotation.
