Embodiment
As shown in Figure 1, multistage angle of cut transmission reduction gear box main mark is 1, comprising: a reduction gear housing 2;
An input shaft 3, A is horizontal arrangement with its longitudinal axis, and is coupled to the live axle of a unshowned motor in a kind of unshowned mode;
An output shaft 4, B is horizontal arrangement with its longitudinal axis, and is coupled to a unshowned application apparatus axle in a kind of unshowned mode; And
A plurality of gearing down levels are limited in the housing 2, and between axle 3 and axle 4.
As known, in use, axle 3 is subjected to the driving of the live axle of a unshowned motor, and axle 4 drives the axle of a unshowned application apparatus.
Referring to Fig. 1 and 2, housing 2 comprises:
An antetheca 5 is positioned at a vertical plane;
A rear wall 6, parallel with antetheca 5;
Two sidewalls 7, be positioned at be parallel to each other and with the perpendicular corresponding vertical plane of wall 5 and plane, 6 place;
(top) wall 8 at the bottom of one is positioned at a horizontal plane; And
A top (end) wall 11, parallel with described wall 8.
Referring to Fig. 1 and 2, axis A and B are vertical mutually and be positioned at the same horizontal plane parallel with 11 with wall 8, and, specifically, be positioned at the neutral position of these walls 8 and 11.In addition, axis A passes the geometrical center of wall 5.
Referring to Fig. 1,2 and 3, axle 3 passes wall 5 projection in housing 2.More specifically, the through hole 12 along axis A is arranged on the wall 5, wherein be equipped with a tubular body 13 that aligns with axis A.The projection from the body 13 of annular flange 14, and by screw to the outer surface of wall 5.Axle 3 runs through body 13, and the one end stretches in the housing 2; Between the internal surface of body 13 and axle 3, be provided with ball bearing 15.
Referring to Fig. 2,3 and 4, in the present embodiment, axle 4 has corresponding position 4a and 4b, and two walls 7 are passed in this position projection.7 upper edge axis B are formed with corresponding through hole 16 at these walls; Corresponding roller bearing 17 is housed in through hole 16.
Referring to Fig. 1 and 2, in the present embodiment, reduction gear box 1 has two retarding stages 18 and 21 in housing 2.Retarding stage 18 constitutes at the spur wheel 22 that forms on the inner end of axle 3 and larger-diameter spur wheel 23 engagements that are keyed onto in the rotating shaft 24 by one, and this rotating shaft is horizontal arrangement with its longitudinal axis C.Retarding stage 21 constitutes by a hypoid gear 25 and crown umbrella gear 26 engagements that are keyed onto axle 4 middle parts that are keyed onto in the rotating shaft 24.Axle 24 is by tubular body 27 supports integrally formed with housing 2.Between the internal surface of body 27 and axle 24, be provided with two roller bearings 28.
Referring to Fig. 2, should be emphasized that retarding stage 21 adopts a gear pair that is made of small gear 25 and crown gear 26, small gear and crown gear are arranged vertically mutually with its axis, and distance X (see figure 3) of the axis B of the axis C of small gear 25 and crown gear 26 skew.Retarding stage 18 adopts a gear pair that is made of spur wheel 22 and spur wheel 23, this gear pair has a distance between shafts Y, and the projection of this distance between shafts Y on the direction of the skew X between the axis B of the axis C of small gear 25 and crown gear 26 equated with skew X self, thereby axis A and axis B are crossing.
By above description, the advantage that this embodiment of the present utility model can realize will be very clear.
Specifically, the axis of the input shaft of reduction gear box and output shaft each other can right angle intersection and is located in the same horizontal plane.Therefore, motor and application apparatus are in same desired location, reduction gear box can be coupled the axle 4, and can be according to the power sense of rotation that will pass to the application apparatus axle, be coupled to the application apparatus axle by the arbitrary position among two position 4a and the 4b, remain to motor simultaneously and have identical how much to the application apparatus axle and be connected.Basically, reduction gear box as the utility model theme can be fixed to wall 8 on the support as diapire, thereby transmission of power is arrived the application apparatus axle with a predetermined sense of rotation, perhaps wall 11 can be fixed on the support as diapire, thereby with opposite direction transmission of power is arrived the application apparatus axle, and this does not need any change is done in reduction gear box inside.Can be used as two-way speed reducer as this reduction gear box of the utility model theme and come work, like this, owing to needn't transform this reduction gear box according to the sense of rotation that will pass to the application apparatus axle, clearly, except that the cost that can reduce the buyer, can also save engineering cost greatly.
In other words, as shown in Figure 2, axis B has identical distance H with wall 6,8,11 distances.
At last, clearly, do not break away from the utility model protection domain, can make amendment and accommodation the reduction gear box 1 that institute describes and illustrates.
Specifically, the axle 4 can be hollow and be contained in the housing 2, position 4a or 4b can form in housing 2 with being connected of application apparatus axle.The axle of hollow 4 is practical, and has the advantage identical with the axle 4 shown in the accompanying drawing.In addition, axle 4 can only have a position to stretch out from housing 2.With comparing that institute describes and illustrates, in housing 2, can have more retarding stage.In this case, retarding stage 21 can be any one-level after the first order, and the skew X between the axis H of the axis C of small gear 25 and crown gear 26 must equal the distance between shafts Y that the determines algebraic sum along the projection that is offset directions X in all other retarding stages.
