Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Fig. 1, the present invention provides a technical solution: a high-efficiency traction machine for an elevator car, including a gearless traction machine 1, the output end of the gearless traction machine 1 is connected to the traction machine shaft 4, without The output end of the gear traction machine 1 and the shaft 4 of the traction machine are equipped with a holding brake 2, which can brake and decelerate the gearless traction machine 1. At the same time, the holding brake 2 has high stability and is more durable. The outer wall of the shaft 4 close to the brake 2 is connected to the traction wheel 3, the outer wall of the left end of the traction machine shaft 4 is connected to the gear 5, the traction machine shaft 4 is movably connected to the rack bar 6 through the gear 5, and the outer wall of the rack bar 6 Gear 5 is set, and the bottom of rack bar 6 is movably connected with stage clip seat 7 by pin shaft, and the outer wall of stage clip seat 7 connects stage clip sheath 8, and the bottom of stage clip seat 7 connects stage clip 9, and the bottom of stage clip 9 The bottom is fixedly connected to the inner cavity bottom of the stage clip sheath 8.

Wherein, the outer wall of the gear 5 connected to the outer wall of the left end of the traction machine shaft 4 is evenly provided with gear teeth, and the outer wall of the rack pressure bar 6 is provided with tooth grooves matching the gear teeth, and the two sets of gears 5 are meshed with each other, so that The gear 5 on the traction machine shaft 4 can be meshed with the gear 5 on the rack pressing bar 6, so that the gearless traction machine 1 can drive the rack pressing bar 6 to rotate;
