Abstract
Disclosed is a gear variable torque type torque wrench. The gear variable torque type torque wrench is mainly composed of a handle, an inner gear ring, a pinion, a connector, a driving claw, a working cavity and a direction selection button. The gear variable torque type torque wrench is characterized in that the inner gear ring and the pinion are internally meshed and are eccentrically arranged, the inner gear ring is positioned in the working cavity of the handle, the handle drives the inner gear ring through the driving claw, the pinion is connected with the connector and is positioned on a pinion shaft in the working cavity, a cover plate enables the inner gear ring and the pinion to be surrounded in the working cavity, the direction of the driving claw is controlled through the direction selection button, and accordingly the driving claw can drive the inner gear ring clockwise or anticlockwise.
Description
Technical field
The present invention relates to a kind of torque spanner, particularly relate to a kind of variable moment type slide torque spanner.
Background technology
Current torque spanner, all based on lever torque spanner.This torque spanner moment of torsion acted on sleeve equals to be applied to the product of power on handle and the arm of force, so just can directly obtain being applied to the moment of torsion on sleeve and nut, can easily according to the rules moment of torsion tighten or loosen nut.But in some occasion; particularly based on the occasion demonstrated, learn; such as when Student Training, match; due to needs frequent operation; if moment of torsion carrys out fastening nut according to the rules, especially easily part of damage, if reduced prescribed torque to protect part; so operator can not obtain torque sensation intuitively, be unfavorable for the raising of study and operative skill.
Summary of the invention
The invention provides a kind of torque spanner, this torque spanner moment of torsion acted on sleeve is not equal to the product of the power on handle of being applied to and the arm of force, but is less than its product.Operator according to the rules moment of torsion operates, but on sleeve, only obtain a smaller moment of torsion, the size of operator to moment of torsion so both can have been made to have and felt intuitively, and can protect part again.
The technical solution used in the present invention is: primarily of handle (1), ring gear (2), pinion (3), joint (4), driving claw (8), the part such as working chamber (10) and set direction button (9) composition, its technical characteristics is: ring gear (2) and pinion (3) internal messing arranged off-centre, ring gear (2) is located in the working chamber (10) on handle (1), handle (1) drives ring gear (2) by driving claw (8), pinion (3) is connected with joint (4), and be located on the pinion shaft (6) in working chamber (10) by the hole (7) of himself, ring gear (2) and pinion (3) are enclosed in working chamber (10) by cover plate (5), driving claw (8) by set direction button (9) controlling party to, make it can with drive ring gear (2) clockwise or counterclockwise.
Accompanying drawing explanation
Fig. 1 is assembling schematic diagram of the present invention.
Fig. 2 is the right view after the present invention removes cover plate.
Fig. 3 is pinion of the present invention and joint schematic diagram.
Detailed description of the invention
Embodiments of the present invention are further illustrated below in conjunction with accompanying drawing.
When needs dismounting nut, first selected the direction of driving claw by set direction button, when acting on a power on handle, this power can pass to ring gear by driving claw, as shown in Figure 1 and Figure 2, then passes to pinion by ring gear, pinion drives joint to rotate, thus completes the dismounting of nut.Because the gear of ring gear is more than the number of teeth of pinion; so the rotating speed of pinion can faster than the rotating speed of ring gear; the moment of torsion that pinion obtains can be less than the moment of torsion that ring gear exports; that is: the moment of torsion acted on joint is less than the moment of torsion be applied on planet carrier; so just both the size of operator to moment of torsion can be made to have to feel intuitively, can part be protected again.
Claims (2)
1. a gear variable moment type slide torque spanner, form primarily of handle, ring gear, pinion, joint, driving claw, working chamber and set direction button, its technical characteristic is: ring gear and pinion internal messing arranged off-centre, ring gear is located in the working chamber on handle, handle drives ring gear by driving claw, pinion is connected with joint, and is located on the pinion shaft in working chamber.
2. a kind of gear variable moment type slide torque spanner according to claim 1, is characterized in that: ring gear and pinion are enclosed in working chamber by cover plate, driving claw by set direction button controlling party to, make it can with drive ring gear clockwise or counterclockwise.
