Abstract

PROBLEM TO BE SOLVED: To obtain a centering jig by which the position measurement and position adjusting work of both pulleies are carried out easily by providing a fixed part fixed to the side surface of either one of a motor side pulley or a pump side pulley and a long body, whose one end is fixed to this fixed part, extended toward the other pulley. SOLUTION: In a motor 1 in the drive part of a hydraulic elevator, a motor side pulley 2 is installed to a motor shaft 1a and a V belt 3 is hung windingly to a V belt groove 2a. In a pump side pulley 4, the V belt 3 is hung windingly to a belt groove 4a. When the relative position between these pulleies 2, 4 is inspected, the fixed surface of the fixed part, 6 consisting of a magnetic body of the centering jig is contacted and fixed to the side surface of the pulley 4. The long body 7 extended toward the other end side so as to be parallel with the fixed surface of the fixed part 6 is extended toward the pulley 2 parallelly with the side surface of the pulley 4. When the clearance is not existed between the long body 7 and the pulley 2 under this state, it is judged that both pulleies 2, 4 stay on a normal position.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centering jig for a hydraulic elevator driving section including a motor and a pump.

[0002]

2. Description of the Related Art In general, a drive section of a hydraulic elevator is composed of a motor and a pump driven by the motor to feed or drain hydraulic oil to a hydraulic jack.

[0003] The transmission of the driving force between the motor and the pump is performed by V-belts wound endlessly around pulleys attached to the motor and the pump.

The two pulleys are disposed so as to be located on a straight line in a direction orthogonal to the axis. However, if one of the pulleys is displaced and is not located on this straight line, the V Since the belt rotates in a wavy manner, there are problems such as generating noise and shortening the life of the V-belt.

Therefore, conventionally, a long body such as a ruler plate has been brought into contact with the side surfaces of the two pulleys, and it has been regularly inspected whether or not the mutual positions are located on a straight line perpendicular to the axis. .

[0006]

However, since the distance between the outer peripheral surfaces of the two pulleys is about 600 mm, it is difficult to accurately check the relative position of the two pulleys while keeping the long body in contact. There was a problem.

If the positions of the pulleys are shifted, the position of the motor is displaced to correct and adjust the position of the motor-side pulley. There is a problem that the body must be brought into contact with the body, and the adjustment work is complicated.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a centering jig for a hydraulic elevator driving unit which can improve the position measurement and position adjustment of the two pulleys.

[0009]

According to the present invention, there is provided a motor having a motor shaft and a motor-side pulley fixed to and rotating on the motor shaft, while being wound around the motor-side pulley. An endless V-belt, and a pump having a pump-side pulley that is wound around the other side of the V-belt and that is driven by the driving force transmitted through the V-belt according to the rotation of the motor-side pulley and that rotates. In the centering jig of the hydraulic elevator drive unit, a fixed portion detachably fixed to one of the side surfaces of the motor-side pulley or the pump-side pulley, and one of the fixed portions fixed to the fixed portion. A long body attached to be parallel to the side surface of the pulley and extending toward the other pulley.

According to the present invention, since the long body is fixed to the side of one of the pulleys by the fixing portion so as to be parallel to the side of the pulley, the unstable body holding the long body in the hand. The distance between the elongated body and the side surface of each pulley can be measured in a stable state, not in a state, and the relative position of both pulleys can be checked with high accuracy.

Also, if the position adjustment operation of the pulley is performed with the elongated body fixed, it is possible to know how far the position correction should be made to bring the two pulleys into the above-mentioned straight line with the cores protruding. It is not necessary to measure the relative position of both pulleys using a long body every time the position is corrected, and the adjustment operation can be performed quickly.

Further, according to the present invention, since the magnetic member is used for the fixing portion, the work of installing and removing the long body can be efficiently performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing a mounting state of a centering jig of a hydraulic elevator driving section according to the present invention, FIG. 2 is a plan view of FIG. 1, and FIG. 3 is a centering jig of a hydraulic elevator driving section of the present invention. It is a perspective view which shows a structure of.

First, the configuration of a drive unit of a hydraulic elevator using the present invention will be described.

In FIG. 1, the motor 1 has a motor shaft 1a and transmits a rotating power to the motor shaft 1a. The motor-side pulley 2 is attached to the motor shaft 1a, and a belt groove 2a is formed on the outer periphery thereof.

The V-belt 3 is formed endless, and a plurality of V-belts are wound around the V-belt groove 2a.

The pump-side pulley 4 has a belt groove 4a on its outer periphery, and the other side of the V-belt 3 is wound around the belt groove 4a.

The pump shaft 5 is mounted on the pump-side pulley 4, and transmits the rotating power of the motor shaft 1a to a pump (not shown) via the motor-side pulley 2, the V-belt 3, and the pump-side pulley 4. The pump is running.

Next, the configuration of the centering jig of the present invention will be described with reference to FIG.

In the figure, the fixing portion 6 is formed of a member having an attraction force, for example, a magnetic material, and has a fixing surface 6b fixed to a pulley and a gap portion 6b having a holding force.

The elongated body 7 is provided at one end with the gap 6b.
And is held by the fixing portion 6, and extends toward the other end side so as to be parallel to the fixing surface 6 a of the fixing portion 6.

Here, the magnetic material may be provided only on the fixing surface 6a, or may be a member having an attractive force such as a suction cup instead of the magnetic material.

Next, a method for checking the relative position between the pulleys 2 and 4 using the centering jig of the present invention will be described with reference to FIGS.

First, as shown in FIG. 2, the fixing surface 6a of the fixing portion 6 is brought into contact with the side surface of the pump side pulley 4 and fixed.

In such a case, the elongated body 7 extends toward the motor-side pulley 2 in parallel with the side surface of the pump-side pulley 4.

Therefore, if there is no gap between the elongated body 7 and the motor-side pulley 2 in this state, it can be determined that the two pulleys are located on the above-mentioned straight line and are in the normal position.

As described above, according to the present embodiment, since the position measurement of both pulleys can be performed in a stable state in which the elongated body 7 is fixed, the inspection work can be performed with high accuracy.

Here, if there is the gap, the position of the motor-side pulley 2 is displaced by displacing the motor 1 to correct the position. However, since the elongated body 7 is held fixed, Since the position correction amount can be known based on the elongated body 7, the position adjustment operation of the pulley can be easily and efficiently performed.

In this embodiment, the pump pulley 4
Although the fixing portion 6 is mounted on the pulley 2, the same effect can be obtained by mounting the fixing portion 6 on the motor-side pulley 2.

[0031]

According to the present invention, since the centering jig is configured as described above, the relative position measurement and position adjustment between the two pulleys of the hydraulic elevator drive can be performed well.
