Description

Locomotive pulley structure with optional counterweight

The present invention relates to a locomotive pulley structure with optional counterweight, and is a mechanical component.

The pulley is one of the components installed on the crankshaft of the locomotive. When the crankshaft rotates, it will push the locomotive belt axially, so that the belt contacts the larger diameter of the pulley, and then changes the transmission ratio to start and accelerate the locomotive;

The weight of the pulley is one of the factors that affect the driving performance of the locomotive. However, the weight of the pulley is fixed in the past and cannot be adjusted according to the driving needs.

In view of the above shortcomings, the inventor believes that it is necessary to correct it. Based on his many years of experience in related technologies and product design and manufacturing, and adhering to the excellent design concept, he researched and created the above shortcomings. After continuous efforts, he finally achieved Launched the locomotive pulley structure with optional counterweight of the present invention, hoping to correct the product structure and improve the product's excellent efficacy.

The main purpose of the locomotive pulley structure with optional counterweight of the present invention is to provide a pulley structure with adjustable weight.

In order to achieve the purpose of exposing, the locomotive pulley structure with arbitrary counterweight of the present invention includes:

A pulley has a disc body, a counterweight part is arranged in the center of the disc body, and a mounting hole runs through the center of the counterweight part, and a plurality of adjustment holes also pass through the counterweight part, and each adjustment hole is opposite to the mounting hole. The holes are arranged in a ring;

At least one adjustment piece is respectively combined with one of the adjustment holes.

The pulley can be assembled on the crankshaft of the locomotive by using the mounting hole, and then play its original function when the locomotive is running;

And when the personnel want to adjust the weight of the present invention according to the driving state of the locomotive, an appropriate number of adjustment parts can be combined with the adjustment holes at appropriate positions to achieve the effect of fine-tuning the weight;

In addition, the counterweight part can be set to be disassembled on the disc body, so that it is convenient for personnel to directly replace the counterweight part with an appropriate weight;

Compared with the previous pulleys, the present invention allows personnel to adjust the weight, so that the locomotive can have the best driving condition, and further improves the shortcomings of general pulleys that cannot adjust the weight. It is obvious that the present invention is a progressive The product.

[Please refer to Figure 1 and Figure 2] The present invention relates to a locomotive pulley structure with optional counterweight, which includes:

A pulley plate (1) has a plate body (11), a counterweight portion (12) protrudes from the center of the plate body (11), and a mounting hole (13) runs through the center of the counterweight portion (12), In addition, the counterweight portion (12) is also penetrated with a plurality of adjustment holes (14), and each adjustment hole (14) is arranged in a ring shape relative to the installation hole (13);

At least one adjustment piece (2) is respectively combined with one of the adjustment holes (14).

[Please refer to the first picture to the third picture] The adjustment piece (2) and the adjustment hole (14) can use bolts and screw holes respectively, and the adjustment piece (2) made of different metal materials such as copper and lead can be manufactured in advance. ), and the adjustment piece (2) can also be made into different sizes and have different weights. When the present invention is used, the pulley (1) is installed on the locomotive crankshaft (3) by using the mounting hole (13) to make it function ;

Later, when you want to adjust the weight of the pulley (1) depending on the running state of the locomotive, you can directly replace the pulley (1) with a different weight of the counterweight (12), or you can also use the adjustment parts with different weights. (2) Lock in different adjustment holes (14) and lock different numbers of adjustment pieces (2) to achieve the effect of weight adjustment.

[Please refer to the fourth figure to the seventh figure] In another preferred embodiment of the present invention, the counterweight part (12) is set as an individual independent from the disc body (11), and the installation hole (13) is connected with the The adjustment hole (14) is also provided in the counterweight part, and the counterweight part (12) is provided with at least one main joint part (15), while the disc body (11) has a through groove (16) running through the center, the through groove ( 16) At least one secondary joint (17) is provided, and when assembled, the main joint (15) and the secondary joint (17) are combined, so that the counterweight (12) is positioned in the through groove (16);

For example, the main joint part (15) is a block protruding from the outside of the counterweight part (12), and the secondary joint part (17) is a card slot recessed on the inside of the through groove (16). The joint part (17) is also recessed with a snap-in opening (171) connected to one side of the disc body (11), so when assembling, the main joint part (15) is snapped into the secondary joint part (17) from the snap-in port (171) Then rotate the counterweight part (12) so that the main joint part (15) touches the end of the secondary joint part (17), and then the counterweight part (12) can be positioned in the through groove (16);

After the assembly is completed, the present invention can be installed on the crankshaft (3) to play its role. The advantage of this embodiment is that the disassembly and assembly of the counterweight (12) is very convenient and quick, so the manufacturer can make a variety of different tools in advance. The weight of the counterweight (12), and then the owner or locomotive maintenance personnel can replace the counterweight (12) with different weights according to the performance requirements of the vehicle, so as to achieve the effect of increasing the starting acceleration or increasing the top speed.

What is described above is only a preferred embodiment of the present invention, and should not be used to limit the scope of the present invention. That is to say, all equivalent changes and modifications made according to the scope of the patent application should still fall within the scope covered by this creation patent.

To sum up, if the invention is novel and progressive, and the invention has not been published in any publication, it shall comply with the provisions of Article 22 of the Patent Law.
