The utility model content
The utility model technical problem to be solved is the inertial defect problem, reduces wear thereby provide a kind of, reduces maintenance cost, backgauge transmission device behind the plate shearing machine of enhancing productivity.
For solving the problems of the technologies described above; The utility model provides backgauge transmission device behind a kind of plate shearing machine; Comprise flange connecting cover on reductor power shaft, motor output shaft, the motor output shaft, the shaft coupling that links to each other with the flange cover, another flange cover that links to each other with shaft coupling; It is characterized in that: on the reductor power shaft, establish a transition gear, with the transition gear travelling gear that is connected with a joggle, the power transmission shaft at travelling gear place is in transmission connection with an end of a pair of mutual flange shaft of docking; The other end of the flange shaft of butt joint connects another flange cover that links to each other with shaft coupling each other, and the distance between axles between power transmission shaft and the reductor power shaft is 75 millimeters.
For being fit to the high speed light loading operation, adopt 314-30 type shaft coupling to substitute original cross forked type shaft coupling.
The good effect of the utility model is: on the reductor power shaft, establish a transition gear; With the transition gear travelling gear that is connected with a joggle, the power transmission shaft at travelling gear place is in transmission connection with an end of a pair of mutual flange shaft of docking, each other another flange cover of linking to each other with shaft coupling of the other end of the flange shaft of butt joint connection; Distance between axles between power transmission shaft and the reductor power shaft is 75 millimeters; Satisfy shaft angle and equate, eliminated additional dynamic load, reduce the wearing and tearing between the connector; Enhance productivity, reduce maintenance cost.

The specific embodiment
With reference to Fig. 1, original QCT plate shearing machine output shaft (motor) is 18 degree with the shaft angle of node line, and the shaft angle of power shaft and node line is 28 degree; Unequal because of two shaft angles, so produce additional angular acceleration, impact is big; Thereby produce additional dynamic load; Wearing and tearing between the aggravation connector cause the part frequent failure, almost change bearing pin weekly one time.
With reference to Fig. 2; The utility model comprise the cover of flange connecting on reductor power shaft 15, motor output shaft 18, the motor output shaft 1, adpting flange cover shaft coupling 2, connect another flange cover 3 of shaft coupling, on the reductor power shaft, establish a transition gear 16, with the transition gear travelling gear 8 that is connected with a joggle; Module: m=2.5; Number of teeth z1=z2=22, the power transmission shaft 12 at travelling gear place is in transmission connection with an end of a pair of mutual flange shaft of docking 4,5, and the other end of the flange shaft of butt joint connects with another flange cover 3 that is connected shaft coupling each other; Realize transmitting motion and power, output torque.The flange Analysis of Nested Design becomes hollow-core construction, and the centre is interior hexagonal hole, the end face flange arrangement.The hexagonal hole function has two; The one, the compensating axial displacement; The 2nd, transmit moment of torsion, motor output shaft equates be 175 degree with power transmission shaft with the shaft angle β 2 of node line with the shaft angle β 1 of node line, and the distance between axles between power transmission shaft and the reductor power shaft is 75 millimeters.Cover plate 6, cover 7 play the security protection effect, are installed on the bearing block 14, and two model 36107 bearings 9 are installed in the inner hole of bearing seat; Bearing block divides two bodies up and down; Its polygon endoporus is consistent with lathe backgauge transmission self-control casing, and bearing block plays support, connection effect, and bolt clamps.Interior dottle pin 10, outer dottle pin 11 play the effect of isolation bearing inner and outer ring, are installed in respectively on flange shaft 5 and the bearing block.13 outer race positioning actions of back-up ring are installed on the bearing block, and end cap 17 seals.Because needle bearing is installed at 314-30 type shaft coupling cross axle place, shaft coupling adopts the flange-type bolt to connect, and adopts 314-30 type shaft coupling to substitute original cross forked type shaft coupling.
The distance between axles computational methods:
As shown in Figure 2, the original equipment motor position does not change before and after transforming, and its axis is L1, with horizontal line angle numerical value is: 9 degree 52 minutes 53 seconds (actual measurement), and the node of shaft coupling is O1; Hollow shaft 12 axis L2, node O2 is about 210 through the level interval of measuring O1 to O2; Shaft coupling two node line O1O2 are L3; Original equipment reductor input axis is L, is about N=93.5 through the distance of measuring O1 to L; The distance of L2 and L is H.
With reference to Fig. 3, be initial point with node O1, set up plane right-angle coordinate:
The L1 equation is that (the motor shaft angle is constant, k1=0.174) for y=k1x
L2 hollow shaft equation is y=h (k2=0)
O2 node abscissa value is M (structure confirms that M is that quantitative value is 210), ordinate be coordinate that h (variable) O2 is ordered be O2 (M, h)
O1O2 straight slope k3=h/M
Straight line L1 and L3 angle are α; Straight line L2 and L3 angle are w
tgα＝k3-k1/1+k1*k3＝(h/M-K1)/(1+k1*h/M)
tgw＝k2-k3/1+k2*k3＝-(h/M)/(1+0)＝-h/M
Shaft angle equates to satisfy tg α=tgw and puts in order:
K1h^2+2Mh-k1M^2＝0
Bring numerical value into following formula, solve h1=18.1; H2=2431 (not conforming to the actual conditions)
H=N-h=93.5-18.1=75.4 calculates according to standard module, and the distance between axles rounding is H=75
Following formula explanation: satisfy shaft angle and equate, have two points, select a distance between axles that satisfies condition to get final product for 75 millimeters according to actual needs.
