The model utility content
The purpose of the utility model is to overcome the defective that exists in the existing technology, and a kind of transmission efficiency height, compact structure, the light and handy energy-saving speed reducer of flexible, with low cost, long service life are provided.
For realizing above-mentioned purpose; The technological scheme of the utility model is the high speed reducer of a kind of transmission efficiency of design, and said speed reducer comprises casing, and the input shaft and the output shaft of setting parallel to each other is installed through radial bearing respectively in the said casing; The input gear is installed on the input shaft; Output gear is installed on the output shaft, it is characterized in that, be separately installed with a thrust-bearing in the radial bearing inboard of said input shaft and output shaft one end; Said input shaft and output shaft are hollow shaft, on the inwall of said hollow shaft, are provided with spline.
Wherein, Be provided with all parallel with output shaft driving shaft and driven shaft through radial bearing in the said casing with input shaft; Input shaft, driving shaft, driven shaft and output shaft are in transmission connection successively; Initiatively king bolt gear and active small helical gear are installed on said driving shaft, driven king bolt gear and driven small helical gear are installed on said driven shaft, be separately installed with a thrust-bearing in the radial bearing inboard of said driving shaft and driven shaft one end.
Said input spiral gear and initiatively gearwheel engagement, initiatively small helical gear and driven king bolt gear engagement, driven small helical gear and the engagement of output spiral gear.
Said input shaft is arranged on the casing center portion.
Said radial bearing is needle bearing or deep groove ball bearing.
Said thrust-bearing is a thrust ball bearing.
The advantage and the beneficial effect of the utility model are: because this speed reducer adopts said structure; The thrust-bearing that driving shaft, driven shaft and output shaft one end are provided with can reduce the frictional force of end ring radially, guarantees the light and handy flexibly of running; Reduce kinetic equation loss, also reduced noise; Input gear, active gearwheel, driven small gear and output gear are spiral gear and can reduce friction between teeth, and stable drive is more suitable at a high speed and heavy load transmission, thereby improves transmission efficiency, increases the service life; Radial bearing is needle bearing or deep groove ball bearing, and thrust-bearing is a thrust ball bearing, is easy to buy and maintenance and repair, and cost is low; The utility model adopts unique way of output, and input eccentric output in center guarantees that compact structure, casing volume are little, and aluminum alloy casing guarantees that the casing overall weight alleviates, thereby has reduced cost; In addition; Bearing hole on casing and the end cap adopts special process to process; Guaranteed the positional accuracy of bearing hole, thereby guaranteed transmission accuracy, reduced resistance and noise: the utility model adopts three grades of gearing down; Simple in structure, rationally distributed, compact structure, transmission be light and handy, flexibly, energy-conserving and environment-protective, be specially adapted to the power transmission of the liquid agitation of food, dairy industry, cold drink, medicine, chemical industry.
