Detailed Description
The present utility model will be described in further detail with reference to the drawings and specific examples, which are not to be construed as limiting the embodiments of the present utility model.
As shown in fig. 1-8, a flanged escalator drive shaft 6 includes a bearing housing 1, a drive sprocket 2, a step sprocket 3, a ratchet assembly 4, a handrail drive sprocket 5, and a shaft 6, the shaft 6 including a drive shaft 601 and a flange 602. Two flanges 602 are symmetrically welded to the drive shaft 601, and the drive shaft 601 passes through the two flanges 602 to expose 2 ends. The 2 ends are rotatably mounted on 2 bearing blocks 1. The 2 step sprockets 3 are mounted outside the 2 flanges 602 by bolts 7. The 2 drive sprockets 2 are mounted on the outer sides of the 2 step sprockets 3 by bolts 7, and the 2 step sprockets 3 are positioned with the drive sprockets 2 by positioning pins 8. The ratchet assembly 4 is welded on the middle part of the transmission shaft 601, the handrail driving sprocket 5 is fixed on the middle part of the transmission shaft 601 by a hot-fitting type, and the ratchet assembly 4 is positioned at the left side of the handrail driving sprocket 5.
The bearing seat 1 is used for fixing the main shaft 6 to enable the main shaft to rotate. The drive sprocket 2 is typically collocated with a plurality of rows of roller chains, through which the drive host transmits power to the drive sprocket 2. The step chain wheel 3 drives the escalator step chain and the steps to move through the torque transmitted by the driving chain wheel 2, thereby realizing the transportation of passengers. The ratchet assembly 4 acts as a brake to the drive spindle 6. The handrail drive sprocket 5 transmits power to the handrail drive shaft through a roller chain, effecting movement of the handrail. The main shaft 6 plays a role in synchronous transmission.
The flange 602 is provided with 4 bolt connection parts 6021,4 and 6021 which are arranged in a cross symmetry manner, and 3 screw holes are formed in the 4 bolt connection parts 6021. The step sprocket 3 is provided with a cross-shaped through hole 302, the cross-shaped through hole 302 and the 4 bolt connecting parts 6021 have the same shape, and the cross-shaped through hole 302 and the 4 bolt connecting parts 6021 are cut by the same blank, so that the loss of materials is reduced, and the utilization rate of the materials is improved. 4 bolt bosses 301,4 bolt bosses 301 are arranged around the cross-shaped through hole 302 in a cross-symmetrical mode. The 4 bolt bosses 301 are respectively provided with 3 screw holes, and the 4 bolt bosses 301 are connected with 4 bolt connecting parts 6021 through bolts 7.
Ratchet assembly 4 includes pinch roller 401, friction plate 402, friction driven wheel 404, and ratchet 403. Friction driven wheel 404 is welded to drive shaft 601 of spindle 6. Ratchet wheels 403 are arranged on two sides of a friction driven wheel 404, a pressing wheel 401 is arranged on the outer side of the ratchet wheels 403, and friction plates 402 are respectively arranged between the pressing wheel 401 and the ratchet wheels 403 and between the friction driven wheel 404 and the ratchet wheels 403. The bolt 7 passes through the friction plate 402, the friction driven wheel 404 and the ratchet 403, and two ends of the bolt 7 are respectively connected with the 2 pressing wheels 401. Pinch roller 401 is positioned with friction plate 402 by dowel pins 8.
The pinch roller 401 is mainly used for clamping the friction plate 402, the friction driven wheel 404 and the ratchet wheel 403, so that the friction plate, the friction driven wheel 404 and the ratchet wheel are fully contacted to generate friction force. Friction plate 402 acts to increase friction. The primary function of friction follower 404 is to generate friction with friction plate 402 and thereby create resistance. Ratchet 403 is adapted to be limited in rotation by the pawl of pawl assembly 9 (a component commercially available in the prior art).
Description of working principle: when the escalator brake device works, the pawl of the pawl assembly 9 props against the ratchet wheel 403 in the ratchet wheel assembly 4, so that the ratchet wheel 403 stops rotating, and simultaneously the driving main shaft 6 makes the friction plate 402 respectively rub with the ratchet wheel 403 and the friction driven wheel 404 under the rotation inertia to generate resistance, so that the escalator brake device achieves the effect of braking.
