Description
Technical field:
The utility model relates to machine industry, is specially a kind of spiral centralized control mechanism.
Background technique:
In Machine Design,, normally use the independent gear shift of handle for the gear shift of gear; But for requiring velocity ratio to change gear shift greatly, want three to four handles to realize usually, the operator uses extremely inconvenient; Particularly in to engineering machinery the hole of boring minor diameter with scrape large diameter, bigger to the speed change difference of transmission device, change frequency with variable-frequency motor usually and realize; But shaving is processed unable at low frequency.
Summary of the invention:
The purpose of the utility model be to provide a kind of rational in infrastructure, be easy to process, be convenient to operate, machining accuracy is high, guarantee the spiral centralized control mechanism of machine power.
The technological scheme of the utility model is: a kind of spiral centralized control mechanism; Comprise transmission shaft, change gear a, change gear b, spiral shaft, transmission umbrella gear a, transmission umbrella gear b, handle shaft, shifting fork bar, guide roller a, guide sleeve a, guide roller b, guide sleeve b, handle, locking nut a, lock screw a, positioning roller a, shift fork a, locking nut b, lock screw b, positioning roller b, shift fork b; Change gear b and change gear a are installed on the transmission shaft; And place shift fork a, shift fork b groove respectively; Transmission umbrella gear a and transmission umbrella gear b are separately fixed on spiral shaft and the handle shaft; Shift fork a and shift fork b are installed on the spiral shaft, and guide roller a is installed among the guide sleeve a, and guide roller b is installed among the guide sleeve b;
Described shift fork a and positioning roller a and guide roller a match, and shift fork b and positioning roller b and guide roller b match;
Described positioning roller a is with in positioning roller b is installed in the different spiral chutes of spiral shaft respectively;
Have different spiral chutes on the described spiral shaft.
The advantage of the utility model is following: two shift forks are placed on the same spiral shaft; Through the manipulation of a handle, realize the gear shift of two change gears, shift fork uses restraint with guide roller and positioning roller; Make it and to move along spiral chute and rectilinear direction; And the variation through spiral chute direction and helical pitch, can realize the conversion of multiple pattern, realize that shift control is simple and direct, stable, make things convenient for.
Description of drawings:
Below in conjunction with accompanying drawing and instance the utility model is further specified.
Fig. 1 is the structural drawing of the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment:
Like Fig. 1,2, shown in 3; Change gear b (2) and change gear a (3) are installed in respectively on the transmission shaft (1); Transmission umbrella gear a (5), shift fork a (17) and shift fork b (21) are installed on the spiral shaft (4), and change gear b (2) places the groove of shift fork b (21), and change gear a (3) places the groove of shift fork a (17); Shift fork a (17) and shift fork b (21) move in the spiral chute of spiral shaft (4) through positioning roller a (16) and positioning roller b (20); Positioning roller a (16) and positioning roller b (20) rotate in lock screw a (15) and lock screw b (19), and its degree of depth is regulated through locking nut a (14) and locking nut b (18), and transmission umbrella gear b (6) is installed on the handle shaft (7); Handle shaft (7) links with shifting fork bar (8); Handle (13) links with the other end of shifting fork bar (8), and guide roller a (9) and guide roller b (11) are installed in respectively in guide sleeve a (10) and the guide sleeve b (12), and in the guiding groove of shift fork a (17) and shift fork b (21), rolls.
The concrete working principle of the utility model:, shifting fork bar (8), handle shaft (7), transmission umbrella gear b (6) are rotated through pulling handle (13); The rotation of transmission umbrella gear b (6) drives transmission umbrella gear a (5) and rotates, thereby spiral shaft (4) is rotated.Because shift fork a (17) and shift fork b (21) place on the spiral shaft (4) through positioning roller a (16) and positioning roller b (20), the rotation of spiral shaft (4) drives shift fork a (17) and shift fork b (21) moves along the spiral chute on the spiral shaft (4).Positioning roller a (16) and positioning roller b (20) are through lock screw a (15) and lock screw b (19) and shift fork a17) and shift fork b (21) tighten together; The degree of depth of lock screw a (15) and lock screw b (19) is regulated through locking nut a (14) and locking nut b (18); Simultaneously; Change gear b (2) places the groove of shift fork b (21), and change gear a (3) places the groove of shift fork a (17), the mobile drive change gear a (3) of shift fork a (17) and shift fork b (21) and the same moved further of change gear b (2); The rotation of change gear b (2) and change gear a (3) is accomplished through the rotation that main transmission drives transmission shaft (1), realizes gear shift.In order to guarantee carrying out smoothly of gear shift, can make the mobile generation sequencing of change gear b (2) and change gear a (3) through the variation of spiral chute pattern.Rotate for preventing that shift fork a (17) and shift fork b (21) from going up at spiral shaft (4); On shift fork a (17) and shift fork b (21), have guiding groove; Guide roller a (9) and guide roller b (11) are housed in groove; Guide roller a (9) and guide roller b (11) are installed in respectively among guide sleeve a (10) and the guide sleeve b (12), and shift fork a (17) and shift fork b (21) are moved along rectilinear direction.
