Detailed Description

The present invention will be described in detail with reference to the accompanying drawings: as shown in fig. 1 to 3, the utility model discloses a gear assembly 1, a promotion subassembly 2 for controlling clutch separation and combination, gear assembly 1 is located capstan winch reel 7 outside and links to each other with the one end of clutch, and promotion subassembly 2 is connected with gear assembly 1, gear assembly 1 includes two gears that are intermeshing, wherein, clutch assembly 3 looks fixed connection in first gear 11 and the clutch, second gear 12 and promotion subassembly 2 looks fixed connection, stir through promotion subassembly 2 and drive gear assembly 1 motion, thereby make clutch assembly 3 come the axis of rotation in the promotion clutch and the separation and combination between the gear, for example: if the pushing assembly is not shifted, the clutch is in a neutral gear state, and if the pushing assembly is shifted, the clutch is in a low-speed or high-speed state. Because the gear assembly and the pushing assembly are positioned outside the winch drum, the whole winch is more compact in structure, simpler in manufacturing process, more convenient to mount, dismount and maintain and more efficient in transmission efficiency.

In order to enable the installation between the first gear and the clutch component to be more efficient and prevent idle rotation between the first gear and the clutch component, a limiting part is arranged between the first gear 11 and the clutch component 3 and comprises a bulge 11-1 arranged on the side surface of the first gear 11 and a groove 3-1 arranged on the axial surface of the clutch component 3, the first gear 11 is limited on the axial end of the clutch component 3 through the matching of the bulge 11-1 and the groove 3-1 and is fastened through a fastening piece in the axial direction, and the fastening piece can be a screw or other connecting pieces with equivalent effects; as shown in fig. 4, the protrusion 11-1 is preferably of a three-jaw structure, and the corresponding groove 3-1 is also of a three-jaw structure, so that the first gear 11 and the clutch assembly 3 do not idle, and not only is the assembly and disassembly convenient, but also the connection strength is better.

In order to make the whole winch space more compact, the tooth surface of the first gear 11 and the tooth surface of the second gear 12 are vertically distributed, and the structural distribution is better than that of a worm and gear type, so that a large transmission ratio can be obtained, the bearing capacity is stronger, and the winch has good self-locking performance, and the clutch performance of the winch is further improved.

The pushing assembly 2 comprises a handle 21 and a connecting shaft 22, one end of the handle 21 penetrates through a mounting hole 41 formed in the housing 4 and is connected with the connecting shaft 22, the other end of the handle 21 is positioned outside the housing 4, and the housing 4 is fixed on the axial end face of the winch shell 5; the structure design not only makes the winch structure more compact, and the installation and the disassembly are more convenient, but also the maintenance of the winch is more convenient because the winch basically works in a severe environment.

The connecting shaft 22 passes through a supporting block 51 arranged on the winch shell 5 and abuts against an axial lug 52 arranged on the winch shell 5, the supporting block 51 is of a lug type structure on the winch shell 5, and the axial end of the axial lug 52 is of a through hole type and is used for installing the clutch component 3 therein; the second gear 12 is mounted on the connecting shaft 22, and the second gear 12 is located between the supporting block 51 and the axial protrusion 52, so that the second gear 12 can be limited at the position, and the transmission efficiency between the gears is more efficient.

The connecting shaft 22 is in a stepped shaft shape, the bottom end of the connecting shaft 22 is abutted against a limiting hole 52-1 arranged on the radial end face of the axial convex block 52, and the radial end face is milled flat, so that the limiting hole 52-1 is in better contact with the bottom end of the connecting shaft for better contact with the second gear 12, and a gasket can be arranged between the limiting hole 52-1 and the second gear for preventing radial play between the limiting hole and the second gear, so that the abrasion of the limiting hole 52-1 can be prevented; the upper end of the connecting shaft 22 abuts against the upper end face of a through hole 51-1 arranged on the supporting block 51, and a gasket can be arranged between the connecting shaft and the supporting block in order to prevent the radial play between the connecting shaft and the supporting block, so that the abrasion of the through hole 51-1 can be prevented; due to the structural design, when the service life is long, if parts need to be replaced, only the gasket needs to be replaced, so that the cost is greatly reduced, and the installation and the disassembly are also convenient; the upper end face of the connecting shaft 22 is connected with the lower end face of the handle shaft body in a limiting connection mode, for example: a radial through groove is processed on the upper end face of the connecting shaft 22, a radial lug is processed on the lower end face of a handle shaft body matched with the radial through groove, the mounting and the dismounting are more convenient, and the handle 21 can drive the connecting shaft 22 due to the fact that the handle shaft body rotates in the circumferential direction.

A limiting component is arranged between the handle 21 and the winch shell 5, the limiting component comprises a spring pin 53 arranged on the winch shell 5 and a limiting groove 21-1 arranged on the shaft body of the handle, the spring pin 53 is inserted into a movable hole 42 (shown in figure 5) arranged on the housing 4, and the spring pin 53 is abutted against the limiting groove 21-1 through shifting of the handle 21. As shown in fig. 6, the limiting groove 21-1 is formed on the radial end surface of the shaft body of the handle, the surface of the limiting groove is a smooth arc surface (which is convenient for the handle to be shifted clockwise and counterclockwise), and the number of the limiting groove is three, wherein the middle one represents a neutral gear of the winch clutch, the clockwise one represents a high gear of the winch clutch, and the counterclockwise one represents a low gear of the winch clutch.

A gasket 6 is arranged between the shaft body of the handle 21 and the mounting hole 41 of the housing 4, one end of the gasket 6 is limited on the shaft body of the handle, and the other end is limited on the mounting hole 41; make the mounting hole of handle axis body and housing difficult wearing and tearing like this, because of the life of capstan winch is longer, do not install packing ring 6 between the two, handle and housing are worn and torn very easily and lead to the change so, have increased use cost, and packing ring 6 has still played the limiting displacement between handle axis body and the mounting hole moreover.

The present invention is not limited to the above embodiments, and any change is made on the shape or material composition, and all the structural designs provided by the present invention are all the deformation of the present invention, which should be considered within the protection scope of the present invention.
