Description

Power transmission component

The present invention relates to a linkage assembly, and more particularly to a power transmission assembly.

Referring to FIG. 1 and FIG. 2, a conventional power transmission assembly 1 includes a transmission shaft 11, a riveting member 12 disposed at one end of the transmission shaft 11, and a transmission member 13 for driving the riveting member 12; The transmission shaft 11 has a shaft 111 and a joint block 112 extending outward from the shaft 111 and having a cylindrical shape. Further, the rivet 12 has a fitting for the engagement block 112 to be worn. a groove 121, and a connecting groove 122 disposed opposite to the fitting groove 121 and connectable to the transmission member 13, and the fitting groove 121 is rounded so that the shaft 111 is inserted into the fitting groove After the 121, the shaft 111 and the rivet 12 are riveted to each other by riveting; then the transmission member 13 is inserted into the connecting groove 122 and is locked in the connecting groove 122; When the external transmission is rotated, the transmission member 11 will interlock the rivet 12 to rotate, and by the riveting force of the rivet 12 and the shaft 111, the transmission shaft 11 is urged together The rivet 12 is rotated to achieve the purpose of interlocking the transmission shaft 11.

However, after the actual use, it is found that the engaging block 112 has a cylindrical shape, and the fitting groove 121 is also circular. When the engaging block 112 is inserted into the fitting groove 121, the fitting groove 121 is formed. The joint block 112 does not have any binding force against rotation, and the joint force between the joint block 112 and the fitting groove 121 is fixed, but the manner of riveting is often unable to withstand a large rotational torque. In the case that the required torque is large, the riveting member 12 is easily idling The transmission shaft 11 is such that the rivet 12 cannot be dynamically and efficiently transmitted to the transmission shaft 11, resulting in loss of transmission power of the power transmission assembly 1, which needs to be improved.

Therefore, the purpose of the present invention is to provide a power transmission assembly that enables the power transmission assembly to withstand greater rotational torque, so that the power transmission assembly can transmit power in a reliable and stable manner.

Therefore, the power transmission assembly of the present invention comprises a transmission shaft, a riveting member disposed at one end of the transmission shaft, and a transmission member for driving the riveting member; wherein the transmission shaft has a shaft and is protruded from the transmission member a joint block at one end of the shaft, and the surface of the joint block is surrounded by a plurality of planes; and the rivet has a fitting groove corresponding to the joint block and for positioning and fitting the joint block And a connecting groove communicating with the engaging groove and connecting the transmission member, wherein the peripheral edge wall of the fitting groove is surrounded by a plurality of end faces; therefore, when the drive shaft and the drive shaft After the rivet members are engaged, when the rivet members are subjected to a rotational torque, they can be mutually abutted through the joint block, the fitting groove or the like, so that the rivet member can effectively interlock the rotation of the drive shaft, and The power transmission assembly is urged to withstand greater rotational torque, so that the power transmission assembly can transmit power in a reliable and stable manner.

Figure 1 is an exploded view of a conventional power transmission assembly; Figure 2 is a cross-sectional view of a conventional power transmission assembly; Figure 3 is an exploded view of a preferred embodiment of the present invention; and Figure 4 is a preferred embodiment of the present invention. Sectional view.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

Referring to FIG. 3 and FIG. 4, in the first preferred embodiment of the present invention, the power transmission assembly 3 includes a transmission shaft 31, a riveting member 32 disposed at one end of the transmission shaft 31, and a linkage of the riveting member 32. The transmission shaft 33 has a shaft 311 and a joint block 312 protruding from one end of the shaft 311, and the surface of the joint block 312 is surrounded by a plurality of planes 3121, and In this embodiment, four planes 3121 are enclosed by a four-corner shape as an example. In addition, the rivet 32 has a fitting groove corresponding to the joint block 312 and the joint block 312 is fitted and positioned. And a connecting groove 322 opposite to the fitting groove 321 and connectable to the transmission member 33, and the fitting groove 321 is formed by a plurality of end faces 3211 being circumferentially connected, and the engaging block 312 is embedded When the fitting groove 321 is fitted into the fitting groove 321, the joining block 312 and the fitting groove 321 can be joined by a fitting connection or a fixed type (for example, riveting).

Continuing with the foregoing, in the embodiment, the transmission member 33 is formed with an anastomosis block 331 at one end thereof, and a ratchet 332 formed at the other end of the transmission member 33 as an example, and the aforementioned anastomosis block is used as an example. The 331 can be placed in the connecting groove 322, and is in a locked state with the connecting groove 322. The ratchet 332 can be driven by a power source (not shown) to generate a rotating power; It is worth mentioning that the other end of the shaft 311 can also be provided with the joint block 312, and the joint block 312 can also be riveted with the riveting member 32, or other devices, in this embodiment The riveting member 32 is provided on both ends of the shaft 311 as an example.

Referring to FIG. 3 and FIG. 4, when the power transmission assembly 3 is operated, that is, the transmission member 33 is driven by the power source to drive the ratchet 332, the transmission member 33 will generate a rotational torque, and The twisting torque is engaged with the connecting groove 322 through the abutting block 331, so that the riveting member 32 is interlocked by the transmission member 33, and the engaging groove 321 is riveted to the engaging block 312 to cause the transmission shaft 31. In addition to the interlocking, the design of the end faces 3211 and the planes 3121 is combined, so that the end faces 3211 and the planes 3121 are mutually abutting, so that the riveting members 32 and the transmission shaft 31 can withstand greater rotational torque. Rather than merely relying on the riveting and bonding force of the rivet 32 and the drive shaft 31, the rotational torque can be interlocked, so that the power transmission assembly 3 can reliably and stably transmit power.

In summary, the power transmission assembly of the present invention is formed by a plurality of planar rings formed by the joint blocks of the drive shaft, and the fitting groove of the riveting member is also surrounded by a plurality of end faces, so that the joint The combination of the block body and the end surface of the fitting groove is in a state of mutual abutment, so that the riveting member and the transmission shaft can withstand a larger rotational torque, instead of relying only on the riveting and bonding force, thereby ensuring The power transmission assembly can transmit power in a reliable and stable manner.
