Abstract
The utility model relates to a gearbox of a hulling machine, which comprises a box body, a drive shaft, a drive shaft and a drive device. The drive shaft and the driven shaft are arranged in the box body in parallel and are respectively connected with the box body through a bearing, and the drive device is connected with the drive shaft through a coupling. The gearbox of the hulling machine is characterized in that the driven shaft is connected with a first driven gear and a second driven gear through splines. The utility model has the advantages that a wear clearance between the driven shaft and a matching gear hole can be avoided effectively, and the gearbox of the hulling machine has a long service life.
Description
Technical field
The utility model relates to a kind of Cereals Processing Machines, particularly a kind of hulling machine speed-changing gear box.
Background technique
The hulling machine speed-changing gear box of prior art all is to adopt flat key to connect between driven shaft and gear.The problem and the shortcoming that exist are: become flexible because flat key is connected in easily to produce under the long-term alternating stress effect, thereby the wearing and tearing between the gear hole that causes driven shaft and match, along with the increase of matching gap, produce high vibration in the time of can causing equipment operation, can't proper functioning.
The model utility content
The purpose of this utility model is to provide a kind of hulling machine speed-changing gear box, it can effectively prevent driven shaft and the gear hole that matches between produce wearing clearance, long service life.
The technological scheme that realizes the utility model purpose is: a kind of hulling machine speed-changing gear box, comprise casing, be arranged in parallel in the casing and the driving shaft and the driven shaft that are connected with casing by bearing respectively, and by the drive unit that coupling is connected with driving shaft, it is characterized in that: driven shaft is connected with first, second driven gear by spline.
And being connected with shifting slide gear on the driving shaft, this shifting slide gear can mesh with first, second driven gear respectively.
And the diameter of described first driven gear and second driven gear is unequal.
And the gear junction, two ends of described shifting slide gear has groove, has slide block one end to be arranged in this groove, and the other end of this slide block is connected with Joystick by driving mechanism.
And described driving mechanism is the rotating shaft that is connected with Joystick, and is the connecting rod that circular motion is done in the center of circle with the rotating shaft, and this connecting rod one end is connected with rotating shaft, and the other end is connected with slide block.
And described drive unit is a motor.
Advantage of the present utility model is: 1. be connected by spline between driven gear and the driven shaft, can effectively prevent driven shaft and the gear hole that matches between produce wearing clearance, long service life.
Description of drawings
Fig. 1 is the sectional view of hulling machine speed-changing gear box plan view.
Fig. 2 is the sectional view of hulling machine speed-changing gear box plan view.
Embodiment
The utility model is described further below with reference to embodiment referring to Fig. 1～2.
The utility model relates to a kind of Cereals Processing Machines, particularly a kind of hulling machine speed-changing gear box, comprise casing 1, the driving shaft 3 and driven shaft 2 that are arranged in parallel in the casing 1 and are connected with casing 1 by bearing respectively, and pass through the drive unit that coupling 7 is connected with driving shaft 3, its distinctive feature is: driven shaft 2 is connected with first, second driven gear 4,5 by spline.
Because it is multiple tooth transmitted load that spline connects, so the bearing capacity height is little to the weakening degree of axle, the centering precision height, steering capability is good, can effectively prevent driven shaft 2 and the gear hole that matches between produce wearing clearance, long service life.
And being connected with shifting slide gear 6 on the driving shaft 3, this shifting slide gear 6 can mesh with first, second driven gear 4,5 respectively.
By mobile shifting slide gear 6, it is meshed with first or second driven gear 4,5 respectively, thereby reach the purpose of speed change.
The diameter that further technological scheme can be described first driven gear 4 and second driven gear 5 is unequal.
Diameter is unequal, when shifting slide gear 6 just can produce different rotating speeds with the engagement of different driven gear, reaches the purpose of speed change.
And the gear junction, two ends of described shifting slide gear 6 has groove, has slide block 11 1 ends to be arranged in this groove, and the other end of this slide block 11 is connected with Joystick 8 by driving mechanism.
Joystick 8 slides vertically by transmission mechanism control slide block 11, also slides on the direction of driving shaft 3 thereby drive the shifting slide gear 6 that cooperates with slide block 11, respectively with 4,5 engagements of first or second driven gear, reaches the purpose of speed change.
Further technological scheme also can be that described driving mechanism is the rotating shaft 9 that is connected with Joystick 8, and is the connecting rod 10 that circular motion is done in the center of circle with rotating shaft 9, and this connecting rod one end is connected with rotating shaft 9, and the other end is connected with slide block 11.
The power that Joystick 8 produces when rotating is passed on the slide block 11 by rotating shaft 9 and connecting rod 10, because rotatablely moving of Joystick 9 by rotating shaft 9 and connecting rod 10, be converted into endwisely slipping of slide block 11 and belong to the classical kind of drive, just do not give unnecessary details its concrete Placement here.
And described drive unit is a motor.
Motor via reducer and coupling 7 to driving shaft 3, drive gearbox with transmission of power.
