Problems solved by technology

[0002] In order to improve the deficiencies of the original elevator, some rack and pinion drive elevator schemes have appeared; these schemes have their own advantages, but there are also some points that need to be improved. For example, the transmission system is more complicated and therefore heavier, and some include multi-stage Speed ​​change, some also have turning (i.e. manual) devices, including handwheels or handles, turning gears, turning clutches, and the entire power system composed of electric motors is relatively heavy, and they are all installed on the elevator car. The load of the elevator car is increased, the energy consumption is increased, and the effective capacity of the elevator car is reduced; in actual use, some elevators do need a large reduction ratio to meet the use requirements

Embodiment 1

[0017] Embodiment 1, an outdoor construction ladder or indoor debris ladder or freight elevator, its structure and accessories Figure 1~4 Roughly the same, the description of the composition and function of its various parts can be found in paragraphs [0004], [0005], [0006], and [0007]. Considering that it matches its rated load, the planetary gear reducer used is a single-stage NGW planetary gear reducer, attached Figure 6 It is a schematic diagram of its transmission system. Its transmission relationship is that the input shaft 51 drives the sun gear 56 to rotate, and the sun gear 56 meshes with the transmission planetary gear 55 to rotate. The ring 54 (the inner surface of the ring is covered with teeth) meshes, and the ring gear 54 is fixed on the reducer housing 52, so the planetary gear 55 rotates on its own, and revolves around the sun gear 56 on the one hand, and drives the planetary carrier 53 through its rotating shaft Rotating around the central axis of the sun g...

Embodiment 2

[0018] Embodiment 2, this is a kind of elevator that load is bigger than embodiment 1, its structure and accessory Figure 1~4 Roughly the same, the description of the composition and function of its various parts can be found in paragraphs [0004] and [0005]. During installation, attention should be paid to the quality of the installation to ensure the necessary accuracy. Including ultrasonic flaw detection for the materials of drive gears and racks, using a laser elevator guide rail verticality measuring instrument to measure the verticality of the guide rails; the "power-off star connection" unit circuit in its electrical control system Figure 5 And [0006] paragraph described the same, its working principle is described in embodiment 1; The difference is that the planetary gear reducer that adopts is a two-stage NGW planetary gear reducer, with Figure 7 It is a schematic diagram of the transmission system, and its transmission relationship is that the input shaft 63 drives...

Embodiment 3

[0019] Embodiment 3, this is a kind of elevator similar to Embodiment 2, its structure and accessories Figure 1~4 Roughly the same, the description of the composition and function of its various parts can be found in paragraphs [0004] and [0005]. During installation, attention should be paid to the quality of the installation to ensure the necessary accuracy. Including ultrasonic flaw detection for the materials of drive gears and racks, using a laser elevator guide rail verticality measuring instrument to measure the verticality of the guide rails; the "power-off star connection" unit circuit in its electrical control system Figure 5And [0006] section described same, its working principle is described in embodiment 1; What adopt is the two-stage NGW planetary gear reducer that has gear coupling, it is not to pass between its high-speed stage and low-speed stage. The intermediate shaft is directly connected, but is connected through a gear coupling. In the planetary gear tra...

Abstract

A pinion-and-rack driven elevator using a planetary gear reducer is characterized in that a power transmission system includes a planetary gear reducer and a synchronous belt transmission system; an electric traction system is a motor system including a permanent magnet direct current motor system or a permanent magnet alternating current synchronous motor system; a right lower drive gear and a right upper drive gear are engaged with a right rack fixed in the vertical direction, and a left lower drive gear and a left upper drive gear are engaged with a left rack fixed in the vertical direction; rolling guide shoe rollers are elastically pressed against non-tooth-shaped guide rail surfaces of the left rack and the right rack and drive an elevator car to move upward or downward; a power loss band-type brake is arranged on a brake wheel coaxial to the motor, and a dual-backup structure is adopted; and an electric interlocked and mechanical interlocked outage star-connection unit circuit is arranged in an electrical control system.
