Problems solved by technology

[0004] Among them, although the design of the planetary gear set can achieve the effect of high reduction ratio, however, there is a problem that the volume is too large, and it is not conducive to further miniaturization design. The reason is that the space occupied by the outer ring gear 524 must be enough for the planetary gears to orbit without being able to shrink any further
Secondly, the tooth profile design and precision requirements between the planetary gear 522 and the sun gear and the ring gear 524 are quite high. If there is a slight error, it will not be able to smoothly rotate around the sun gear. There is a danger of breaking the shaft due to the incompatibility between the
In addition, the planetary gear set is also criticized for its structural parts that are prone to resonance response and excessive noise.

Abstract

The invention discloses an impact tool. The impact tool comprises a motor, an impact mechanism and a gear assembly; the motor is provided with an output shaft rotating around a first axis; the impactmechanism is provided with a driving shaft, and the driving shaft rotates around a second axis, and the second axis is not parallel to the first axis; and the gear assembly is driven by the output shaft to drive the impact mechanism, and the gear assembly comprises a reduction gear set, a bevel gear set and a gear set, wherein the reduction gear set is coupled with the output shaft, the bevel gearset is coupled with the reduction gear set and is driven by the reduction gear, and the gear set is coupled with the bevel gear set and the driving shaft and is driven by the bevel gear set to drivethe impact mechanism. Therefore, through the design of the gear assembly, the impact tool has the advantages of being simple in structure, low in noise and the like, the overall size of the impact tool can be effectively reduced, and the miniaturization design is facilitated.

Description

technical field [0001] The present invention relates to impact tools; more particularly, to an impact tool incorporating a novel gear assembly. Background technique [0002] In modern industrial applications, in order to tighten or loosen fasteners (such as screws, nuts, etc.), in addition to using a general screwdriver or wrench, most users today think of using impact tools (or Power tool), the impact tool can provide high torque and high impact force, can effectively and quickly lock or loosen fasteners, so as to achieve twice the result with half the effort. Not only that, but the impact tool can be used in many different applications according to different tool heads. For example, the tool head can be a tool head with specific functions such as an electric drill bit, a screwdriver bit, a wire saw bit, or other tools. Types of tool heads. [0003] In order to facilitate the operation in narrow places, some companies have developed patents such as U.S. No. 9022888 "Angle...
