Abstract

The invention discloses a speed change mechanism for a speed reduction gear box. The speed change mechanism is characterized by comprising a slide shaft, a slide gear and an internal gear; the slide gear sleeves the slide shaft, and the internal gear sleeves dual gears via reamed hole bolts; two shifting blocks which respectively sleeve a shifting fork are fixed by the aid of cotter pins and are clamped in clamp grooves of the slide gear, a shifting fork rod is inserted into the other end of the shifting fork, a speed regulating handle is welded on a connecting rod, and the connecting rod sleeves the shifting fork rod; the speed regulating handle can be shifted, so that the connecting rod can drive the shifting fork rod to turn the shifting fork, the shifting blocks on the shifting fork shift the slide gear, the slide gear can reciprocate on the slide shaft, and a low speed effect can be realized when the slide gear is shifted until the slide gear is meshed with the internal gear; when shifted to the other side of the internal gear, the slide gear can be directly meshed with a gear of a next shaft system, and a high speed effect can be realized. The speed change mechanism has the advantages that a lever principle is adopted, the speed regulating handle is shifted, accordingly, high and low speeds of equipment can be conveniently switched over, and the speed change mechanism is simple and feasible in structure, low in cost and suitable for popularization and application.

Description

A kind of gear for gear reduction box
Technical field
The present invention relates to mechanical manufacturing field, is exactly a kind of gear for gear reduction box.
Background technique
Gear reduction box is applied very extensive in machinery industry, when the output speed of motor is from driving shaft input, drive pinion rotation, and small gear drives gearwheel motion, and the gear ratio small gear of gearwheel is many, the rotating ratio small gear of gearwheel is slow, then is exported by the axle (output shaft) of gearwheel, thereby plays the effect that output is slowed down; Gear reduction box, according to the needs of practical application, has a variety of forms, has one-level transmission, secondary transmission, three grades of transmissions etc.; But no matter be a few utmost point transmissions, conventional gear reduction box determines after velocity ratio, output speed is just definite, and, in the situation that input shaft rotating speed has been determined, the rotating speed on output shaft also can only be unique; As required, speed change gear speed reducer has been invented in design to people,, in same gear reduction box, has designed two even more velocity ratios, and the transmission of many sleeve gears is set, and realizes speed governing with gear; The gear adopting in gearbox at present, different manufacturers adopts different means and scheme, varied, and in use, a lot of users react speed change trouble, difficulty, even have the situation of not changing gear, and easily cause device damage; There is no in the market solution of the above problems.
Summary of the invention
The present invention has overcome the defect in prior art, and a kind of gear for gear reduction box is provided, and it can be realized under various use states, throw-over engage a gear fast.
The technological scheme that solution the technology of the present invention problem is taked is:
For a gear for gear reduction box, it is characterized in that: include slip shaft, be sleeved on the shifting slide gear on slip shaft, be sleeved on the internal gear on duplicate gear by hinged bolts; Two pulling blocks cotter pin being set on fork is fixed, and pulling block is stuck in the draw-in groove of shifting slide gear, and the other end of fork inserts fork bar, and speed regulating handle is welded on connecting rod, and connecting rod is sleeved on fork bar.
A kind of gear for gear reduction box, it is characterized in that: stir speed regulating handle, make connecting rod drive fork bar to rotate fork, the pulling block on fork is stirred shifting slide gear and can be moved around on slip shaft, shifting slide gear pulls out when engaging with internal gear, realizes transmission at a slow speed; Pull out to neutral position, realize neutral gear; Pull out to the opposing party, shifting slide gear is directly fastened gear with next axle and is engaged, and realizes quick transmission.
For a gear for gear reduction box, it is characterized in that: described internal gear is bonded to each other with internal gear and be fixedly connected with by strand drilling bolt.
For a gear for gear reduction box, it is characterized in that: described connecting rod is sleeved on fork bar, and fork bar is sleeved on fork, suit place is square hole and connects.
Effect of the present invention:
The present invention adopts lever principle, by stirring speed regulating handle, and the fast conversion at a slow speed of the equipment of just can realizing easily, simple in structure feasible, with low cost, be suitable for and apply.
Brief description of the drawings
Fig. 1 is speed change gear sectional view of the present invention.
Fig. 2 is speed regulating mechanism sectional view of the present invention.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of gear for gear reduction box, is characterized in that: include slip shaft 1, be sleeved on the shifting slide gear 2 on slip shaft 1, be fixedly set in the internal gear 3 on duplicate gear 4 by hinged bolts 5; Two pulling blocks, the 7 use cotter pins 8 that are set on fork 6 are fixed, and pulling block 7 is stuck in the draw-in groove of shifting slide gear 2, and the other end of fork 6 inserts fork bar 9, and speed regulating handle 11 is welded on connecting rod 10, and connecting rod 10 is sleeved on fork bar 9.By stirring speed regulating handle 11, make connecting rod 10 drive fork bar 9 to rotate fork 6, pulling block 7 on fork 6 is stirred shifting slide gear 2 and can be moved around on slip shaft 1, when shifting slide gear 2 pulls out when engaging with internal gear 3, realize at a slow speed, when pulling out to the opposing party, make shifting slide gear 2 directly fasten gear with next axle and engage, realize fast.
