Description

Technical Field

[0001] The invention relates to a special tool and method for installing a 5KW generator pulley, belonging to the technical field of motor installation and maintenance. Background Art

[0002] The generator pulley is an important component of the generator, which realizes power transmission through a fixed belt. The pulley is fastened to the pulley shaft through the nut on its shaft. In actual installation and maintenance operations, when the nut is tightened with a wrench or other tools, the pulley shaft tends to rotate with the nut. The pulley shaft can be clamped to prevent rotation using a universal tool, but universal tools have the disadvantage of being inconvenient to operate on the one hand, and on the other hand, mechanical damage to the pulley shaft is easily caused when the universal tool is used to clamp the pulley shaft and tighten the nut. Summary of the invention

[0003] The technical problem solved by the present invention is: to overcome the shortcomings of the prior art, and to provide a 5KW generator pulley installation special tool and installation method, which are applied to the motor pulley installation and maintenance operation process. The concave serrated disc and the center hole of the wheel shaft that precisely bites the wheel shaft, together with the long handle, the clamp and the clamp teeth, play a role in fixing the wheel shaft during the process of screwing in and out the wheel shaft nut. On the one hand, the tool is convenient for installation and maintenance operations, and on the other hand, it can avoid mechanical damage to the wheel shaft compared with general tools.

[0004] The technical solution of the present invention is: a special tool for installing a 5KW generator pulley, comprising a handle, a clamping tooth, a serrated disc, a connecting shaft, a clamp and a serrated disc cover;

[0005] A handle and a clamp are fixedly connected to form a single-sided clamp; two single-sided clamps are hinged through a connecting shaft, and the clamp ends of the two single-sided clamps form a cavity;

[0006] The sawtooth disk is located in the cavity and contacts the inner walls of the clamp ends of the two single-sided clamps;

[0007] A hollow cylindrical hole is provided at the center of the sawtooth disk for placing a belt pulley shaft with threads to be fixed.

[0008] Furthermore, a frosted section is provided at the rear end of the handle.

[0009] Furthermore, the handle is a solid iron cylinder.

[0010] Furthermore, the inner side of the clamp is provided with clamp teeth which mesh with the saw teeth on the outer side of the sawtooth disk.

[0011] Furthermore, the clamp teeth of the two single-sided clamps are at different positions.

[0012] Furthermore, a serrated disk cover is provided on the serrated disk to restrict the axial movement of the serrated disk in the fixture.

[0013] Furthermore, the diameter of the serrated disk cover is larger than the diameter of the serrated disk.

[0014] Furthermore, the hollow cylindrical hole of the sawtooth disk has the same cross-sectional shape as the pulley shaft to be fixed.

[0015] Furthermore, a 5KW generator pulley installation method implemented by a 5KW generator pulley installation special tool comprises the following steps:

[0016] Align the pulley shaft to be fixed with the central hollow cylindrical hole of the sawtooth disk and insert it, then clamp the sawtooth disk with two single-sided clamps;

[0017] Check whether the serrated disc cover fits well with the two single-sided clamp surfaces; if so, hold the handle tightly;

[0018] Screw the nut into or out of the thread of the pulley shaft to be secured;

[0019] Loosen the two single-sided clamps and remove the serrated disk to complete the installation.

[0020] The advantages of the present invention compared with the prior art are:

[0021] (1) The present invention uniquely designs a central hole that matches the cross-sectional shape of the target pulley shaft, so that the pulley shaft and the special tool can be seamlessly engaged, achieving the effect of fixing the axle with zero angular displacement during the process of screwing the nut in and out. Using a general tool to fix the axle is likely to cause slippage during the process of tightening the nut;

[0022] (2) The present invention ensures labor-saving, safe and convenient installation operation by designing the clamp with a long handle and inner teeth. It avoids the possible danger or damage to the operator, axle and other parts caused by using general tools;

[0023] (3) The present invention is an installation method based on the tool shape and comprehensively considers safety, convenience, and efficiency, thereby saving time and effort in the operation process and achieving the effects of convenient installation and safe maintenance.

[0029] In order to better understand the above technical scheme, the technical scheme of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0030] The following is a further detailed description of a 5KW generator pulley installation special tool provided in the embodiment of the present application in conjunction with the accompanying drawings of the specification. The specific implementation method may include (such as Figures 1 to 3 As shown): a handle 2, a frosted section 1 at the end of the handle, a clamp 8, clamp teeth 3, a serrated disk 4, a serrated disk cover 9 and a connecting shaft 5.

[0031] In the solution provided in the embodiment of the present application, the frosted section 1 at the end of the handle is anti-slip, thereby increasing the friction between the palm and the handle 2.

[0032] Furthermore, in a possible implementation, the handle 2 is a solid iron cylinder, and has an anti-slip frosted section 1 at its end.

[0033] In a possible implementation, the outer edge of the clamp teeth and the outer edge of the serrated disk are complementary in shape, and the clamp teeth 3 restrict the sliding and rotation of the serrated disk 4 in the clamp.

[0034] Furthermore, the clamp 8 is provided with clamp teeth 3 on its inner side which can engage with the saw teeth of the sawtooth disk 4; the left and right clamps have the same appearance except for the clamp teeth 3.

[0035] Optionally, the serrated disk cover 9 is located at the front of the tool, and its diameter is larger than the outer diameter of the serrated disk 4, so as to play a blocking role and restrict the serrated disk 4 from moving axially.

[0036] In a possible implementation, the sawtooth disk 4 has a center hole, and the cross-sectional profile of the center hole matches the cross-sectional profile of the generator pulley shaft.

[0037] Further, the operation process of using the tool to install the motor pulley is as follows:

[0038] refer to Figure 4 , align the center hole of the sawtooth disk 4 with the wheel axle and insert it, then clamp the sawtooth disk 4 with a clamp;

[0039] Check whether the serrated disc cover 9 is in good contact with the surface of the fixture. To ensure that the serrated disc cover 9 is in good contact with the surface of the fixture, hold the handle tightly with one hand at the frosted section of the handle.

[0040] refer to Figure 5 , use a wrench or other tool to screw the nut in or out;

[0041] Loosen the clamp, remove the serrated disc 4, and check to ensure that the nut is in the predetermined position.

[0042] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.

[0043] The contents not described in detail in the specification of the present invention belong to the common knowledge of those skilled in the art.
