Problems solved by technology

[0003] However, in the process of transmitting torque during the normal operation of the existing shaft lock mechanism, although the parts used for locking are in an unlocked state, unnecessary contact will always occur between them, resulting in impact and friction, thereby reducing the tool. efficiency, and the problem of excessive heat generation

Embodiment Construction

[0028] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0029] refer to Figure 1 to Figure 9 As shown, the torque output tool of the present invention is a screwdriver 100 as a preferred embodiment. Certainly, it may also be a torque output tool such as an electric drill or a torque wrench.

[0030] The screwdriver 100 includes: a housing 101 , a motor (not shown in the figure) and a transmission assembly (not shown in the figure). Wherein, the motor and the transmission assembly are arranged in the casing 101 .

[0031] The casing 101 is used to accommodate components such as a motor and a transmission assembly so that they form a whole. The motor is used as a power source to output torque through its motor shaft, which is used as a torque input for the entire transmission assembly.

[0032] As a more specific solution, in order to realize the adjustment of speed and torque, the transmis...

Abstract

The invention discloses a torque output tool and its one-way torque transmission mechanism, which comprises: a casing, a motor and a transmission assembly, the motor and the transmission assembly are arranged in the casing, the transmission assembly includes a one-way torque transmission mechanism, and the one-way torque transmission mechanism Including: main shaft, driving part, lock sleeve, lock core, lock piece, etc., the lock sleeve includes a lock ring, the lock core includes a cylinder, and the inner wall of the lock ring includes at least two sections that can be locked or loosened with the outer wall of the lock cylinder cylinder The limiting wall surface of the locking part, the locking part is arranged between the locking ring and the cylinder, under the action of centrifugal force, when the driving part is driven to the main shaft, it only contacts the locking sleeve stably without unnecessary impact and friction , improve the efficiency of torque transmission, and reduce the heat generated by this mechanism, so as to reduce the adverse effects of temperature rise on tool reliability.

Description

technical field [0001] The invention relates to a power output tool and its transmission mechanism, in particular to a torque output tool and its one-way torque transmission mechanism. Background technique [0002] Torque output tools represented by electric drills, screwdrivers, etc. are very commonly used power tools, and their working components can be drill bits, bits, etc. When designing this type of tool, in order to protect the motor and facilitate the replacement of tool components, the transmission mechanism of this type of tool is often equipped with a shaft lock mechanism that allows the tool to only transmit torque from the power source to the main shaft in one direction. . [0003] However, in the process of transmitting torque during the normal operation of the existing shaft lock mechanism, although the parts used for locking are in an unlocked state, unnecessary contact will always occur between them, resulting in impact and friction, thereby reducing the to...
