Abstract
The utility model discloses a new single-side twin drive decelerator, comprising a high-speed gear shaft (1),a second drive shaft (4), a third drive shaft (5) , a gear and a supporting bearing. Wherein the gear and the supporting bearing are both sleeved on a drive shaft. The utility model is characterized in that two pairs of double annular spherical surface roller bearings (2) are sleeved on two sides of a central gear which is arranged on the high-speed gear shaft (1) and a hole which is drilled on a bearing cap of the double annular spherical surface roller bearing (2), is communicated with an oil groove (3) which is in the double annular spherical surface roller bearing (2). The utility model adopting the double annular spherical surface roller bearing not only guarantees the concentricity when in machining and makes the working life longer than that of the original bearing but also makes the lubricating oil easily pass through the oil groove to achieve forced lubrication.
Description
One, technical field:
The utility model belongs to retarder, specifically, relates to the two gearing speed-reducers of a kind of novel single-side.
Two, background technique:
Monolateral pair of transmission grinding machine retarder is widely used in building material industry, is the novel driving device of grinding machine.It is bulky that this retarder has overcome the center transmission speed reducer, and the occupation of land space is big, the equipment investment height, and the manufacture cycle is also than many shortcomings such as length.Form by main gear reducer, mill body bull gear and seal closure, auxiliary drive, lubricant oil station and control system.Adopt the parallel axis hard-tooth surface design of gears, the small gear that drives on bull gear on the grinding machine and speed reducer two output shafts meshes simultaneously, forms three grades of gearing down of power dividing, constitutes the power dividing Synchronous Transmission train of tuber grinder transmission system.
The monolateral pair of gearing speed-reducer is a transmission of power reducing gear in the said system, and it mainly comprises high speed gear shaft 1, second transmission shaft 4, the 3rd transmission shaft 5, and gear on the transmission shaft and spring bearing (as shown in Figure 1).In existing monolateral pair of gearing speed-reducer, high speed gear shaft 1 adopts four cylindrical roller bearings and an angular contact bearing supporting, and angular contact bearing is four-point supporting, for avoiding producing harmful effect, the cooperation of middle main supporting should be tighter, and bearings at both ends cooperates pine.Because the number of bearings of an axle upper support is too many, bearing span reaches 3 meters, can't disposable processed finished products, and concentricity can't guarantee.In addition, because the roller bearing that adopted does not have oil groove, thereby can only the depending nozzle oil jet lubrication, often cause lubricated insufficiently, bearing temperature be higher, causes bearing life to shorten.
Three, model utility content:
The purpose of this utility model provides and a kind ofly can guarantee concentricity, and the two gearing speed-reducers of lubricated sufficient novel single-side.
For reaching above-mentioned purpose, concrete scheme of the present utility model is: design the two gearing speed-reducers of a kind of novel single-side, comprise high speed gear shaft, second transmission shaft, the 3rd transmission shaft, and gear on the transmission shaft and spring bearing, its key is: the central gear both sides on described high speed gear shaft are set with two pairs of double row self aligning spherical roller bearings, be drilled with the hole on the bearing cap of this double row self aligning spherical roller bearing, this hole communicates with oil groove in the described double row self aligning spherical roller bearing.
High speed gear shaft described in the utility model is supported by two double row self aligning spherical roller bearings of gear the right and left, is convenient to the assurance that casing adds the concentricity in man-hour.Adopt double row self aligning spherical roller bearing that lubricant oil is entered from the oil groove at bearing middle part, bearing can fully obtain to lubricate.
Adopt the advantage of technique scheme to be: simplified difficulty of processing, the concentricity in the time of guaranteeing casing processing, fully lubricated, bearing temperature is low, long service life.
Four, description of drawings:
Fig. 1 is the structural representation before monolateral pair of gearing speed-reducer improves.
Fig. 2 is the utility model structural representation.
Five, embodiment:
See also Fig. 2, the utility model is mainly by high speed gear shaft 1, second transmission shaft 4, the 3rd transmission shaft 5, and be sleeved on compositions such as gear on the transmission shaft and spring bearing, its main points are, central gear both sides on described high speed gear shaft 1 are set with two pairs of double row self aligning spherical roller bearings 2, be drilled with the hole on the bearing cap of this double row self aligning spherical roller bearing 2, this hole communicates with oil groove 3 in the described double row self aligning spherical roller bearing 2.
High speed gear shaft adopts two cover double row self aligning spherical roller bearings to support, with former five bearings relatively, can not only guarantee concentricity, and lubricant oil can be easy to enter by bearing oil groove and reach pressure lubrication, improve than former bearing working life.Span between two main bearings was 730mm originally, was 1220mm now, and winding degree meets the demands as calculated.
Claims (1)
