Description

An Improved Balancer Pendulum Transmission Device

technical field

The utility model relates to a dynamic balancing device for a rotor of a rotating machine, in particular to an improved pendulum transmission device for a balancing machine.

Background technique

Based on the following three factors, the currently used pendulum drive of the balancing machine has been improved:

1. The two pendulums are driven by the same chain and independent sprockets. The power is manual, and the swing range of the rocker arm is limited. Therefore, when moving the pendulum, the labor intensity is high and the efficiency is low, especially when the two pendulums need to be changed frequently. Especially when the distance between the racks;

2. The balancing machine is not equipped with a pendulum distance measuring device or a ruler, and the moving distance of the pendulum needs to be measured while moving. The single-person operation is cumbersome, time-consuming and labor-intensive, and the cooperation of two people is more efficient;

3. There is no limit switch installed on the track. If it is changed to electric, there is a risk of overtravel in the displacement of the swing frame.

Contents of the invention

The purpose of the utility model is to provide an improved pendulum transmission device of a balancing machine, which is accurate in positioning, quick in operation and convenient in completion, and can greatly reduce the operation intensity.

The utility model provides an improved pendulum transmission device for a balancing machine. Two first transmission screw rods and second transmission screw rods with opposite directions of rotation are connected through a coupling. The outer end of the screw rod and the coupling are respectively equipped with bearing housings, and the bearing housings are respectively installed on the base. The outer end of the first driving screw rod is connected with a driving motor and/or the outer end of the second driving screw rod is connected with a hand crank. A crosshead is respectively installed on the first driving screw rod and the second driving screw rod, and a pendulum push rod is installed on the cross head. , A scale that can move along the length of the track is installed on one side of the base.

In the above, the limit switch assembly for controlling the moving distance of the swing frame is installed on the base.

Among the above, there is a square hole at one end of the hand crank to cooperate with the square pin at the outer end of the second drive screw.

In the above, the limit switch assembly is composed of a limit switch, a switch support, a locking handle, and a locking slider. The locking slider is installed on the T-shaped slot on the base, and the locking handle and the locking slider are threaded. When it is connected, the limit switch assembly is fixed when it is tightened, and the limit switch assembly can be moved when it is unscrewed.

The beneficial effects of the utility model:

The semi-automatic and accurate positioning of the rack can be realized, and the whole process can be quickly completed by a single operation, which greatly reduces the intensity of human operation and improves efficiency. The device is simple to control and easy to operate, and is worthy of popularization.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1 and Fig. 2, the utility model provides an improved balancing machine pendulum transmission device, two first transmission screw rods 1 and second transmission screw rods 9 with opposite directions of rotation are connected by a coupling 12, in the Bearing housings 10 are installed on the outer end of the first driving screw rod 1, the outer end of the second driving screw rod 9 and the coupling 12, the bearing housings 10 are installed on the base 6 respectively, and the outer end of the first driving screw rod 1 is connected with a drive Motor 13, driving motor 13 is supported by motor support 14, and the second drive screw mandrel 9 outer ends are connected with crank handle 11, and hand crank handle 11 one end has square hole to cooperate with the square pin of second drive screw mandrel 9 outer ends, convenient disassembly. A crosshead 8 is respectively installed on the first transmission screw rod 1 and the second transmission screw rod 9, and a pendulum push rod 7 is installed on the cross head 8, and the two ends of the pendulum push rod 7 are connected with the pendulum frame 5 respectively, 5 Installed on the track on the base 6, a scale 15 that can move along the length of the track is installed on one side of the base 6, and the horizontal movement of the scale 15 is not restricted; the zero point is located in the middle of the scale 15; the value marked on the scale 15 is When the zero point is in the middle of the two pendulums 5, the distance between the two pendulums 5 is convenient for positioning and measurement.

A limit switch assembly for controlling the moving distance of the pendulum 5 is installed on the base 6, and the space between the pendulum 5 is placed according to the needs, which can prevent the overtravel of the pendulum 5 and limit the moving distance of the pendulum 5, so that the two pendulums The space between the racks 5 just reaches the user's needs. The limit switch assembly is composed of a limit switch 4, a switch support 3, a locking handle 2, and a locking slider 16. The locking slider 6 is installed on the T-shaped groove on the base 6, and the locking handle 2 and the locking The slide block 16 is connected by threads, the limit switch assembly is fixed when tightened, and the limit switch assembly is movable after unscrewed.

During use, as shown in FIG. 1 , move the scale 15 so that the bottom edge of the swing frame 5 is located at the same scale of the scale 15 , then the zero point of the scale 15 is located in the middle of the two swing frames 5 . Move the limit switch assembly to the required spacing value and lock it. Start the drive motor 13, or shake the hand crank 11 to drive the first drive screw 1 and the second drive screw 9 to rotate, and push the swing frame push rod 7 through the crosshead 8 connected with the screw rod, and the swing frame The push rod 7 pushes the two swing frames 5 to move. After the swing frames 5 touch the limit switch 4, the driving motor 13 stops, and the swing frames 5 stop moving and reach the designated position. Still can manual handle 11 under the situation that drive motor 13 fails, and two pendulums 5 still move simultaneously. Such improvement reduces labor intensity and improves efficiency.
