Abstract
The utility model discloses a bevel gear assembling structure of an electric chain saw. The bevel gear assembling structure comprises a gear box and a motor rotor, wherein a first bevel gear and a second bevel gear are arranged inside the gear box, the first bevel gear is meshed with the second bevel gear, one end of the gear box is provided with a shaft hole, and one end of the motor rotor penetrates through the shaft hole and is connected with the second bevel gear. The motor rotor is provided with a bearing which is arranged inside the shaft hole, the outer end of the shaft hole is provided with a lock piece used for preventing the bearing from sliding outward, and the lock piece abuts against the bearing and is fixedly connected with the gear box. Compared with the prior art, the bevel gear assembling structure is reasonable in structural design, the outer end of the bearing is provided with the lock piece to effectively prevent the second bevel gear from sliding outward, and therefore the correct meshed position of the second bevel gear is prevented from changing, the gears are prevented from shaving, and service life is prolonged.
Description
Technical field
The utility model relates to the electric chain saw technical field, is specifically related to a kind of bevel gear assembly structure of electric chain saw.
Background technique
All drive the first bevel gear by the second bevel gear in the bevel gear assembly structure of existing electric chain saw, owing to after bearing and rotor are fixing axial internal clearance is arranged, in transmission process, under the reaction force of the first bevel gear, the second bevel gear is outwards slippage easily, makes large the second bevel gear depart from correct engaging position, thereby cause the shaving phenomenon, cause failure of gear transmission, when particularly the first bevel gear was the plastic cement gear, the phenomenon of the first bevel gear shaving was particularly outstanding.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of reasonable in design, can guarantees that large the second bevel gear in correct engaging position work, increases the service life.
For achieving the above object, the utility model provides following technological scheme: a kind of bevel gear assembly structure of electric chain saw, comprise gear-box and rotor, the first bevel gear and the second bevel gear are installed in the described gear-box, the first bevel gear and the engagement of the second bevel gear, described gear-box one end is provided with axis hole, rotor one end passes axis hole and is connected with the second bevel gear, be provided with bearing on the described rotor, and bearing is installed in the axis hole, described axis hole outer end is provided be used to the locking element that prevents the outside slippage of bearing, and described locking element withstands bearing and is fixedly connected with gear-box.
By adopting technique scheme, withstand the bearing outer end by locking element, can effectively prevent the outside slippage of the second bevel gear, thereby guarantee that the correct engaging position of large the second bevel gear does not change, and guarantees not shaving of gear.
The utility model further is set to: described locking element is locking pressure plate, and locking pressure plate is fixedly connected with gear-box by screw.By this setting, locking pressure plate is simple in structure, reliable operation.
The utility model also further is set to: described locking pressure plate is 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.By this setting, the locking pressure plate reasonable in design makes work more reliable.
The utility model also further is set to: described second bevel gear the inner is provided with nut, and the second bevel gear is by nut check.By this setting, the second bevel gear location is reliable.
The utility model has the advantages that: compared with prior art, the utility model reasonable in design, the bearing outer end is provided with locking element, can effectively prevent the outside slippage of the second bevel gear, thereby guarantee that the correct engaging position of large the second bevel gear does not change, guarantee not shaving of gear, increase the service life.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.

Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the sectional view of A-A among Fig. 1;
Fig. 3 is the utility model embodiment's explosive view.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the bevel gear assembly structure of the disclosed electric chain saw of the utility model, comprise gear-box 1 and rotor 2, the first bevel gear 3 and the second bevel gear 4 are installed in the described gear-box 1, the first bevel gear 3 and 4 engagements of the second bevel gear, described gear-box 1 one ends are provided with axis hole 11, rotor 2 one ends pass axis hole 11 and are connected with the second bevel gear 4, be provided with bearing 5 on the described rotor 2, and bearing 5 is installed in the axis hole 11, described axis hole 11 outer ends are provided be used to the locking element 6 that prevents bearing 5 outside slippages, and described locking element 6 withstands bearing 5 and is fixedly connected with gear-box 1.
Described locking element 6 is locking pressure plate, and locking pressure plate 6 can be fixing by clamping or welding and gear-box 1, and present embodiment preferably locking pressure plate 6 is fixedly connected with gear-box 1 by 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 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 the utility model reliable operation, described the second bevel gear 4 the inners are provided with nut 8, the second bevel gears 4 by nut 8 lockings.
During practical application, rotor 2 drives the second bevel gear 4, the second bevel gear 4 drives 3 transmissions of the first bevel gear, in transmission process, the first bevel gear 3 has reaction force and imposes on the second bevel gear 4, force the moving tendency of the second bevel gear 4 oriented left displacements, but because locking pressure plate 6 is fixed on the gear-box 1, locking pressure plate 6 is withstood bearing 5, bearing 5 withstands the second bevel gear 4, make the second bevel gear 4 can not be to moving to left, thereby guarantee that the correct engaging position of large the second bevel gear does not change, and guarantees not shaving of gear.
Above-described embodiment is to specific descriptions of the present utility model; only be used for the utility model is further specified; can not be interpreted as the restriction to the utility model protection domain, the technician of related domain makes some nonessential improvement and adjusts the utility model according to the content of above-mentioned model utility and all falls within the protection domain of the present utility model.
