Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator hoisting machine, and more particularly to an elevator hoisting machine in which tooth contact adjustment of a reduction gear using parallel shafts is improved.

[Background of the invention]

The conventional elevator hoisting machine was developed in 1988-1270.
As described in Japanese Patent Application No. 83, a steel wheel of an elevator hoist is supported by a reduction gear box, and the other end is supported by a bearing support by a bearing disposed outside the reduction gear box. In this structure, the reducer box that supports the bearing and the bearing support are mounted on the base separately, so the parallelism of the input shaft and output shaft depends on the mounting position of the bearing support, especially when the gear teeth are in contact with each other. and cause gear noise. Therefore, when adjusting the movement of the bearing support in the vertical direction, a liner is placed at the bottom of the bearing support, and in the left-right direction, the entire bearing support is moved and adjusted using adjustment bolts. This structure has a problem in that the entire bearing support body is moved and adjusted, and the basic parts are moved for vertical and horizontal adjustments, which requires a lot of time for the adjustment work.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator hoisting machine that allows easy adjustment of parallelism errors in gear shafts of a speed reducer.

[Summary of the invention]

In order to keep the noise of the reducer low, it is necessary to properly adjust the tooth contact of the gears. This adjustment is made by moving the axis up, down, left and right.The present invention makes it possible to easily make fine adjustments up, down, left and right by using a wedge with a slope of about 1/10. The load is transmitted through the

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. 1 is a front view of the elevator. On the floor of a machine room 2 provided above the hoistway 1, a hoist 3 is supported by a vibration isolator 4, and a steel wheel 5 of the hoist is supported. A main rope 7 is wound around the deflection wheel 6, and one end of the main rope 7 is fixed to a seat 8, and the other end is fixed to a counterweight 9. On one side of the reducer box 20 fixed on the base 10, the electric motor 11 is fitted and fixed with a flange, and on the other side is a steel wheel 5 and a bearing that supports the output shaft 14 on the side opposite to the reducer from the suspension core of this steel car. A support 13 is provided to which the brake 12 is attached. Output shaft 1
4, the reduction gear side is supported by the bearing 15 and the end bracket 16.
is fixed with a presser lid 17, and is fitted and supported in the opening of the reducer box. Furthermore, a large gear 19 that meshes with a small gear 18 on the input shaft side is provided at the shaft end of the output shaft 14 to transmit power to the input shaft. A bearing 15 and a bearing box 21 for fixing the bearing are arranged on the side of the bearing support 13, and there is a space between the bearing support 13 and the bearing box 21 that allows the input shaft to absorb the parallelism error of the output shaft as shown in FIG. A gap δ is provided. In addition, in order to adjust the bearing box in the vertical direction a1 and the horizontal direction a2, a groove 27 with a slope is provided on the lower surface and side surface of either the bearing support 13 side or the bearing joint 21, and the pattern 22 is pulled out in the axial direction. The bearing box 21 is arranged so that it can be moved in the axial direction with bolts 23 from the flange portion of the bearing box 21. After adjustment, the bearing box 21 is fixed to the bearing support body with a fixture 24. Although the wedges 22 are shown at two locations in FIGS. 4 and 5, they may be provided at four locations symmetrically for adjustment. FIGS. 6 and 7 show other embodiments, in which the bearing support 13 and the bearing box 21 are made into square surfaces, and the same effect can be obtained even if the wedges 22 are inserted from the four corners for adjustment.

By configuring the bearing support in this manner, the tooth contact can be adjusted easily at the bearing cylinder portion without having to move the entire bearing support to adjust the tooth contact of the gear. Further, even if a large suspension load of the elevator is applied to the bearing portion, the force is transmitted to the bearing support body through the stem, so that no bending occurs in the flange surface of the bearing box or the mounting bolt 24. Therefore, there are effects such as being able to reduce the size of the bearing box and bolts.

〔Effect of the invention〕

The tooth contact can be adjusted by tightening the bolts on the bearing box without having to move the entire bearing support to adjust the tooth contact, which has the effect of making the adjustment work easier.
