Description

Technical Field

[0001] This utility model relates to the field of starter technology, and in particular to an auxiliary starter that is easy to maintain. Background Technology

[0002] The starter in the prior art is a device that releases the mechanical energy stored in a wound spring through a mechanism, converting it into kinetic energy, thereby starting a diesel or gasoline engine.

[0003] However, in the existing technology, starters are all one-piece structures, with all components mounted on the housing. When internal parts such as gears and spindles are damaged, the pawl assembly and coil spring must be removed from the bottom before they can be replaced or repaired, which is very inconvenient, time-consuming, and labor-intensive. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide an auxiliary starter that is easy to maintain, making maintenance more convenient.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an auxiliary starter that is easy to maintain, having a housing, one end of which is provided with an end cover, and the end cover is provided with a ratchet assembly, a starter arm assembly and a transmission assembly, the ratchet assembly being connected to one end of a spindle via the transmission assembly, the other end of which is connected with a pawl assembly, and a coil spring being fitted on the spindle.

[0006] In the above technical solution, the inner end of the coil spring is mounted on the spindle, the outer end of the coil spring is mounted on the coil spring post on the coil spring cover, and the coil spring cover is fixedly connected inside the housing.

[0007] In the above technical solution, the outer periphery of the coiled spring cover is provided with multiple limiting grooves, and the inside of the housing is provided with multiple limiting protrusions that can cooperate with the limiting grooves, and the limiting protrusions are engaged in the limiting grooves.

[0008] In the above technical solution, the coil spring is disposed in the cavity formed by the housing and the coil spring cover.

[0009] In the above technical solution, the housing is provided with an installation platform, and the end cap is mounted on the installation platform.

[0010] In the above technical solution, the transmission assembly includes a main gear mounted on the ratchet assembly and a driven gear mounted on the spindle.

[0011] In the above technical solution, the end cap is provided with a ratchet cover, and the ratchet assembly is disposed in the ratchet cover.

[0012] In the above technical solution, the starting arm assembly is located on one side of the ratchet assembly and can extend into the ratchet cover to drive the ratchet assembly to rotate.

[0013] In summary, the advantages of the present invention over traditional technologies are as follows: the present invention changes the integrated housing of the starter in the prior art into a split structure, which consists of a housing and an end cover. The transmission component and ratchet component are both located on the end cover. When internal components are damaged, maintenance can be performed simply by removing the end cover, making maintenance very convenient. Attached Figure Description

Detailed Implementation

[0022] Based on the preferred embodiments of this utility model, and through the following description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.

[0023] The present invention will be further described with reference to the following figures:

[0024] like Figures 1-6As shown, an easy-to-maintain auxiliary starter has a housing 100. One end of the housing 100 is provided with an end cover 200. The end cover 200 is provided with a ratchet assembly 300, a starter arm assembly 400 and a transmission assembly 500. The ratchet assembly 300 is connected to one end of a spindle 600 through the transmission assembly 500. The other end of the spindle 600 is connected to a pawl assembly 700. A coil spring 800 is fitted on the spindle 600.

[0025] The inner end of the coil spring 800 is mounted on the spindle 600, and the outer end of the coil spring 800 is mounted on the coil spring post 812 on the coil spring cover 810. The coil spring cover 810 is fixedly connected inside the housing 100.

[0026] like Figure 5 As shown, the outer periphery of the coil spring cover 810 is provided with multiple limiting grooves 811, and the interior of the housing 100 is provided with multiple limiting protrusions 120 that can cooperate with the limiting grooves 811. The limiting protrusions 120 are engaged in the limiting grooves 811. The coil spring cover 800 is fixedly connected to the housing 100 by two bolts, and the cooperation between the limiting protrusions 120 and the limiting grooves 811 is used to limit the coil spring cover 800, prevent shaking during operation, and ensure stable operation.

[0027] like Figure 4 As shown, the housing 100 is provided with an installation platform 110, the end cover 200 is installed on the outside of the installation platform 110, and the coil spring 800 is disposed in the cavity formed by the housing 100 and the coil spring cover 810. The cavity can be regarded as an integrated coil spring chamber. This structure can improve the safety of disassembly and avoid danger when disassembling the coil spring 800. On the other hand, it can also improve the overall sealing of the pull-free device.

[0028] like Figure 3 , 4 As shown, the transmission assembly 500 includes a main gear 510 mounted on the ratchet assembly 300 and a driven gear 520 mounted on the spindle 600.

[0029] like Figure 1 As shown, the end cap 200 is provided with a ratchet cover 210, and the ratchet assembly 300 is disposed in the ratchet cover 210. The ratchet cover 210 can protect the ratchet assembly 300.

[0030] like Figure 1 As shown, the starting arm assembly 400 is disposed on one side of the ratchet assembly 300 and can extend into the ratchet cover 210 to drive the ratchet assembly 300 to rotate.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
