Abstract
The invention discloses an energy-saving transmission main shaft which includes a cylinder body, wherein threaded holes are formed in the two end surfaces of the cylinder body; the cylinder body includes a plurality of cylinder sections; the every two cylinder sections are in step transition; a limiting groove is formed in the cylinder body on the left side and at the connection part of the every two cylinder sections, and extends in the radial direction of the cylinder body. The energy-saving transmission main shaft ensures no radial or axial movement of the main shaft during the gear shifting of the transmission, and avoids inaccurate gear shifting caused by radial and axial movement.
Description
Technical field
The present invention relates to speed changer accessory manufacturing technology field, especially the main shaft of energy-saving transducer.
Background technique
Speed changer will carry out gear switch in the process realizing speed change, transmission main shaft is namely in order to realize this function, therefore main shaft position in mission case just can not be moved, and the restriction only disclosed in prior art main shaft axial position, and radial position does not effectively limit, main axle moving, transforming gear inaccuracy when this just causes shift of transmission.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose the main shaft of energy-saving transducer, can guarantee that speed change is when shifting gears, main shaft, while not moving radially, can not move axially, and avoids the coarse problem of consequent transforming gear.
In order to realize foregoing invention object, the invention provides following technological scheme:
The main shaft of energy-saving transducer, comprises cylinder, and the two ends end face of described cylinder all has tapped hole,
Described cylinder comprises some sections of cylindrical bodys, is step transition between every two sections of described cylindrical bodys, and the described cylindrical body in every two sections of described cylinder connection places, left side has restraining groove, and described restraining groove extends along described cylindrical body radial direction.
Further, cylindrical body is provided with two restraining grooves every section described, two described restraining grooves are positioned at these cylindrical body both sides axisymmetricly, and each restraining groove on described cylinder is parallel to each other.
Further, described restraining groove cross section is spill, semicircle or V-arrangement.
Further, described restraining groove bearing of trend runs through described cylinder.
The main shaft of energy-saving transducer of the present invention, can guarantee that speed change is when shifting gears, main shaft, while not moving radially, can not move axially, and avoids the coarse problem of consequent transforming gear.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the main shaft of energy-saving transducer of the present invention;
Fig. 2 is the schematic top plan view of the main shaft of energy-saving transducer of the present invention.
Embodiment
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
The main shaft of energy-saving transducer as shown in Figure 1-2, comprises cylinder 1, and the two ends end face of described cylinder 1 all has tapped hole 3,
Described cylinder 1 comprises some sections of cylindrical bodys 11, is step transition between every two sections of described cylindrical bodys 11, and the described cylindrical body 11 in every two sections of described cylindrical body 11 joints, left side has restraining groove 2, and described restraining groove 2 extends along described cylindrical body 11 radial direction.
Cylindrical body 11 is provided with two restraining grooves, 2, two described restraining grooves 2 every section described and is positioned at these cylindrical body 11 both sides axisymmetricly, and each restraining groove 2 on described cylinder 1 is parallel to each other.
Described restraining groove 2 cross section is spill, semicircle or V-arrangement.
Described restraining groove 2 bearing of trend runs through described cylinder 1.
During use, mounting limit plate in mission case, the number of limiting board is corresponding with the number of restraining groove 2 and position, agrees to that two limiting boards on cross section are positioned at main shaft both sides, when mission case put into by main shaft, restraining groove 2 coordinates with limiting board and carries out axial limiting to main shaft.Meanwhile, main shaft two ends are fixed on mission case by tapped hole 3, secure main shaft further.
The main shaft of energy-saving transducer of the present invention, can guarantee that speed change is when shifting gears, main shaft, while not moving radially, can not move axially, and avoids the coarse problem of consequent transforming gear.
