Description

Change and turn to the device that obtains unidirectional different rotating speeds

Technical field

This model utility relates to a kind of automatically controlled unidirectional pair of rotating speed outputting power device, and a kind of specifically change turns to the device that obtains unidirectional different rotating speeds.

Background technique

Drive transfer production line, the semi-automatic production line of present China, carry out a kind of constant transporting velocity, be that motor driving reducer slows down, on output shaft, obtain a constant speed, be applied directly in the production line then, this retarder can not change output speed according to factors such as conditions of manufacture, environment, personnel, particularly can not adapt to realize needs fast, the jogging speed conversion in the corresponding time.

Summary of the invention

This model utility to provide a kind of change motor forward and backward to, and can obtain the device of single two kinds of friction speeds that turn at output terminal.

Solve the technological scheme that its technical problem adopts: this device is by motor, gear, axle, clutch, sprocket wheel and chain are formed, have three axles, i.e. spool (X1), axle (X2) and axle (X3), on axle (X1), be connected with the clutch of gear (Z2) and two counterturns, on axle (X2), be connected with sprocket wheel (A2) and gear (Z3), on axle (X3), be connected with gear (Z4) and sprocket wheel (B2), be connected with gear (Z1) on the motor (D), gear (Z1) and gear (Z2) engagement, a clutch is connected with sprocket wheel (A2) by chain (L1), the engagement of gear (Z3) and gear (Z4), another clutch is connected with sprocket wheel (B2) on spool (X3) by chain (L2); Axle (X3) is an output shaft.

Clutch is a free wheel device, " internal rotor " is housed (A) and (B) in two clutches respectively, outside each " internal rotor ", all be set with shell sprocket wheel (A1) and (B1), sprocket wheel (A1) is connected with the sprocket wheel (A2) of axle on (X2) by chain (L1), and sprocket wheel (B1) passes through chain (L2) and is connected with sprocket wheel (B2) on spool (X3); Electrical switch is installed on the motor.

Beneficial effect: owing to adopted such scheme, wherein clutch A, B " internal rotor " (forward and reverse), gear Z2 is fastening is installed on the X1, clutch outer member sprocket wheel A1, B1 are sleeved on the clutch " internal rotor ", axle X2 tightens sprocket wheel A2 and gear Z3 is installed, axle X3 tightens gear Z4 and sprocket wheel B2 is installed, motor D driven gear Z1, gear Z2 engagement on gear Z1 and the axle X1, when clutch A is closed, a clutch outer member sprocket wheel A1 and an axle X2 upper sprocket wheel A2 are in transmission connection, axle X2 Z3 and the axle X3 Z4 engagement that cogs that cogs; When clutch B was closed, the sprocket wheel B2 on clutch outer member sprocket wheel B1 and the axle X3 was in transmission connection, and an axle X3 is an output shaft, when motor is just changeing or reversing, can obtain the output of counterclockwise rotation to different rotating speeds at axle X3, has reached the purpose of this utility model.This model utility is skillfully constructed, reasonable in design, as long as by changing gear and sprocket wheel, axle X3 goes up and can obtain needed two kinds of rotating speeds that counterclockwise direction is different, with the need of work of suitable different occasions.If increase axle X4 and one group of gear again, newly-increased axle can obtain the output that two kinds of positive hour hands turn to different rotating speeds, and this device is applicable to the single workplace that turns to friction speed.

Description of drawings

Fig. 1 changes the structural representation that turns to the device that obtains unidirectional different rotating speeds for wanting model utility;

Embodiment

Embodiment 1: this installs by motor, gear, axle, clutch, sprocket wheel and chain are formed, clutch A wherein, B " internal rotor " (forward and reverse), gear Z2 is fastened on the X1, clutch outer member sprocket wheel A1, B1 is sleeved on the clutch " internal rotor ", axle X2 tightens sprocket wheel A2 and gear Z3 is installed, axle X3 tightens gear Z4 and sprocket wheel B2 is installed, motor D driven gear Z1, gear Z2 engagement on gear Z1 and the axle X1, when clutch A is closed, clutch outer member sprocket wheel A1 and axle X2 upper sprocket wheel A2 are in transmission connection, the gear Z3 of axle on the X2 and the axle X3 Z4 engagement that cogs, when clutch B was closed, clutch outer member sprocket wheel B1 and axle X3 upper sprocket wheel B2 were in transmission connection.

Electrical switch is installed on the motor, changes direction.

(counterclockwise direction) rotating speed is no when motor reverses, it is n1 that gear Z1 makes an X1 obtain the clockwise direction rotary speed by gear Z2, the closed work of clutch A this moment, drive the rotation of clutch outer member sprocket wheel A1 clockwise direction, rotate with n2 speed thereby drive axle X2 upper sprocket wheel A2 clockwise direction; The gear Z3 of axle X2 drives axle X3 with counterclockwise rotation by gear Z4 again, and speed is n3, promptly exports first kind of counterclockwise direction rotating speed, and speed is the power of n3.This moment axle X3 upper sprocket wheel B2 drives the clutch B shell upper sprocket wheel B1 counterclockwise rotation on the axle X1, this moment since clutch B shell sprocket wheel B1 speed (inhour) less than clutch B " internal rotor " speed (clockwise), but clutch B is still not closed.Though clutch A is loaded on the same axle X1 mutual noninterference during work with B by installation direction is different.

When motor just changes, (clockwise direction) rotating speed is no, making an X1 obtain counterclockwise rotation speed by gear Z1, Z2 is n1, the closed work of clutch B this moment, drive clutch outer member upper sprocket wheel B1 counterclockwise rotation, the sprocket wheel B2 that directly drives on the axle 3 by chain L2 works, and makes an X3 obtain second kind of power that counterclockwise rotation speed is n4.Though this moment is by gear Z3, sprocket wheel A2 on the gear Z4 on the axle X3, the axle X2, and the sprocket wheel A1 on the axle X1, make an X1 clutch A shell sprocket wheel A1 obtain a kind of clockwise direction rotational speed, but its speed goes up clutch A " internal rotor " speed (counterclockwise direction) greater than axle X1, clutch A is not closed, so yet mutual noninterference during work.

According to actual conditions, by changing gear Z1, Z2, Z3, Z4 and sprocket wheel A1, A2, B1, B2, can obtain needed two kinds of rotating speeds that counterclockwise direction is different on the axle X3, to be suitable for the need of work of different occasions.

This device is applicable to the single workplace that turns to friction speed.

Embodiment 2: if increase axle X4 and one group of gear again, axle X4 can obtain the different rotating speeds of two kinds of clockwise direction rotations.
