Abstract
The invention discloses a bevel gear assembly structure of an electric chain saw. The bevel gear assembly structure comprises a gear case and a motor rotor, wherein a first bevel gear and a second bevel gear are arranged in the gear case and are engaged with each other; a shaft hole is arranged on one end of the gear case; one end of the motor rotor penetrates through the shaft hole so as to be connected with the second bevel gear; a bearing is arranged on the motor rotor and is arranged in the shaft hole; and a locking piece for preventing the bearing from slippage outwards is arranged on the outer end of the shaft hole, supports the bearing and is fixedly connected with the gear case. Compared with the prior art, the bevel gear assembly structure has a reasonable design; and the locking piece is arranged on the outer end of the bearing, so that the second bevel gear can be effectively prevented from slippage outwards, an accurate engagement position of the second bevel gear is ensured to be unchanged, gears are ensured to be unshaved, and the service life is prolonged.
Description
Technical field
The present invention relates to the electric chain saw technical field, be specifically related to a kind of bevel gear assembly structure of electric chain saw.
Background technique
All drive first bevel gear in the bevel gear assembly structure of existing electric chain saw, because bearing and rotor have axial internal clearance after fixing, in transmission process by second bevel gear; Under the reaction force of first bevel gear, second bevel gear is outwards slippage easily, makes big second bevel gear depart from correct engaging position; Thereby cause the shaving phenomenon; Cause failure of gear transmission, when particularly first bevel gear was the plastic cement gear, the phenomenon of the first bevel gear shaving was particularly outstanding.
Summary of the invention
Deficiency to existing technology exists the object of the present invention is to provide a kind of reasonable in design, can guarantee that big second bevel gear in correct engaging position work, increases the service life.
For realizing above-mentioned purpose, the invention provides following technological scheme: a kind of bevel gear assembly structure of electric chain saw comprises gear-box and rotor; First bevel gear and second bevel gear are installed in the said gear-box; First bevel gear and the engagement of second bevel gear, said gear-box one end is provided with axis hole, and rotor one end passes axis hole and is connected with second bevel gear; Said rotor is provided with bearing; And Bearing Installation is in axis hole, and said axis hole outer end is provided with the locking element that is used to prevent the outside slippage of bearing, and said locking element withstands bearing and is fixedly connected with gear-box.
Through adopting technique scheme, withstand the bearing outer end by locking element, can effectively prevent the outside slippage of second bevel gear, thereby guarantee that the correct engaging position of big second bevel gear does not change, and guarantees not shaving of gear.
The present invention further is set to: described locking element is a locking pressure plate, and locking pressure plate is fixedly connected with gear-box through screw.Through this setting, locking pressure plate is simple in structure, reliable operation.
The present invention also further is set to: described locking pressure plate is a circular ring, and rotor passes the through hole at locking pressure plate center, and the diameter of this through hole greater than with the diameter of the rotor of rotor joint.Through this setting, the locking pressure plate reasonable in design makes work more reliable.
The present invention also further is set to: said second bevel gear the inner is provided with nut, and second bevel gear is through nut check.Through this setting, second bevel gear location is reliable.
Advantage of the present invention is: compared with prior art, reasonable in design of the present invention, the bearing outer end is provided with locking element; Can effectively prevent the outside slippage of second bevel gear; Thereby guarantee that the correct engaging position of big second bevel gear does not change, guarantee not shaving of gear, increase the service life.
Below in conjunction with Figure of description and embodiment the present invention is described further.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the sectional view of A-A among Fig. 1;
Fig. 3 is the explosive view of the embodiment of the invention.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the bevel gear assembly structure of electric chain saw disclosed by the invention comprises gear-box 1 and rotor 2; First bevel gear 3 and second bevel gear 4 are installed in the said gear-box 1; First bevel gear 3 and 4 engagements of second bevel gear, said gear-box 1 one ends are provided with axis hole 11, and rotor 2 one ends pass axis hole 11 and are connected with second bevel gear 4; Said rotor 2 is provided with bearing 5; And bearing 5 is installed in the axis hole 11, and said axis hole 11 outer ends are provided with the locking element 6 that is used to prevent bearing 5 outside slippages, and said locking element 6 withstands bearing 5 and is fixedly connected with gear-box 1.
Described locking element 6 is a locking pressure plate, and locking pressure plate 6 can be fixing through clamping or welding and gear-box 1, and present embodiment preferably locking pressure plate 6 is fixedly connected with gear-box 1 through screw 7.This technological scheme, locking pressure plate 6 is easy to connect with gear-box 1, connects reliable.Described locking pressure plate 6 is a circular ring, and rotor 2 passes the through hole at locking pressure plate 6 centers, and the diameter of this through hole greater than with the diameter of the rotor of rotor 2 joints.
For making reliable operation of the present invention, said second bevel gear 4 the inners are provided with nut 8, the second bevel gears 4 through nut 8 lockings.
During practical application, rotor 2 drives second bevel gear, 4, the second bevel gears 4 and drives 3 transmissions of first bevel gear; In transmission process, first bevel gear 3 has reaction force and imposes on second bevel gear 4, the tendency that forces second bevel gear, 4 oriented left bit to move; But because locking pressure plate 6 is fixed on the gear-box 1; Locking pressure plate 6 is withstood bearing 5, and bearing 5 withstands second bevel gear 4, makes second bevel gear 4 can not be to moving to left; Thereby guarantee that the correct engaging position of big second bevel gear does not change, and guarantees not shaving of gear.
The foregoing description is to specific descriptions of the present invention; Only be used for the present invention is further specified; Can not be interpreted as the qualification to protection domain of the present invention, the technician of related domain according to the content of foregoing invention the present invention is made some nonessential improvement and adjustment all falls within protection scope of the present invention.
