Description
Technical field
The utility model relates to a kind of electronic, garden instrument, and more particularly, it relates to the tooth box transmission mechanism of a kind of angle grinding machine.
Background technology
At present, there is following defect in existing angle its running part of grinding machine, one, assembling defect: first its running part of conventional angular grinding machine loads tooth case with after front and back pad clamping wool felt, then load antislip ring and bearing be pressed into tooth case simultaneously, collar in assembling again, then rotor axis of electric is through the bearing inner race in tooth case, finally in tooth case, assemble pinion and locking nut, this kind of mode installation step is many, and in the little space of tooth case rigging pilotage gear and nut, there is assembling process complexity, the problem of length consuming time, two, its aeration structure generally adopts wind scooper to improve air circulation, increase intake, but air-flow easily spins in the position of electric tool air outlet and does not flow out, thus cause the problems such as the too high and damage of inner original paper temperature.Therefore the running part on the grinding machine of angle needs improvement badly.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of easy to assembly, time saving and energy saving, well-ventilated, the tooth box transmission mechanism of the angle grinding machine of long service life.
For achieving the above object, the utility model provides following technical scheme to realize:
The tooth box transmission mechanism of a kind of angle grinding machine, comprise tooth case, be engaged in the rotor on described tooth case and be fixed on the wind loop of rotor end, bearing, antislip ring, front pad, wool felt, rear pad and pinion is disposed with between described rotor and tooth case, bearing arm-tie is combined with between described rotor and bearing, be combined with air-ducting ring between described rotor and tooth case, this air-ducting ring is arranged on the opposite side of the relative wind loop of rotor.
As preferably: described bearing arm-tie both sides are extruded with guiding projection, and the sidewall of described tooth case offers the embeded slot suitable with guiding projection.
As preferably: described air-ducting ring comprises leading and joins frame and be arranged on several wind deflectors of leading and joining around frame uniformly, and this wind deflector is arranged to tooth case lopsidedness from rotor.
As preferably: described tooth case is also provided with the tensioned screw arranged with coaxial bearing, the end of described tensioned screw is fastened with bullet pad.
As shown from the above technical solution, the beneficial effect of this practicality is:
Compared to existing technology, tool has the following advantages, 1. by original for jump ring in bearing axial limiting change to bearing arm-tie with make originally must substep to install in tooth case inside that the structure that fill be improved as can in outside integral installation, and fit into tooth case together, it is exterior due to all parts are placed on tooth case, efficiency is high, simple to operate, 2. owing to the addition of air guide ring structure on the basis of traditional air chute improving countermeasure, can effectively by passive for swirling eddy derivation, air-flow is rotating by oblique wind deflector and discharges tooth case, wind effect is obvious, effectively reduce inner original paper temperature, significantly improve service life.
Accompanying drawing explanation
Fig. 1 is the explosive view of the tooth box transmission mechanism of a kind of angle of the utility model grinding machine.
Detailed description of the invention
Be described further with reference to the embodiment of Fig. 1 to the tooth box transmission mechanism of a kind of angle of the utility model grinding machine.
The tooth box transmission mechanism of a kind of angle grinding machine, comprise tooth case 1, be engaged in the rotor 2 on tooth case 1 and be fixed on the wind loop 3 of rotor 2 end, bearing 4, antislip ring 5, front pad 6, wool felt 7, rear pad 8 and pinion 9 is disposed with between rotor 2 and tooth case 1, bearing arm-tie 10 is combined with between rotor 2 and bearing 4, also be combined with air-ducting ring 11 between rotor 2 and tooth case 1, this air-ducting ring 11 is arranged on the opposite side of the relative wind loop 3 of rotor 2.
Bearing arm-tie 10 both sides are extruded with guiding projection 101, the sidewall of tooth case 1 offers the embeded slot 12 suitable with guiding projection 101, between guiding projection 101 with embeded slot 12 coordinate the installing for all parts provide convenient one block one draw in complete assembling, further convenient for assembly, it should be noted that: then outstanding formation guiding projection in like manner also can be convenient for assembly for the sidewall of bearing arm-tie 10 all right indent formation groove tooth case 1.
Air-ducting ring 11 comprises leading and joins frame 111 and be arranged on several wind deflectors 112 of leading and joining around frame 111 uniformly, wind deflector 112 is arranged from rotor 2 to tooth case 1 lopsidedness, air-flow can effectively be derived by oblique wind deflector 112, the size at wind deflector 112 inclination angle is determined by the size of fan page and rotating speed, changes arrange to improve maximum efficient wind effect along with both changes.
Tooth case 1 is also provided with the coaxial tensioned screw 13 arranged with bearing 4, the end of tensioned screw 13 is fastened with bullet pad 14, tensioned screw 13 is located overall for running part axial tightening by bearing 4, improves the degree of integration of tooth case running part, avoids because of the lax noise caused.
The assembly technology of this practicality is as follows: antislip ring 5 is then put into tooth case 1 by axle bearing arm-tie 10, bearing 4, rear pad 8, wool felt 7, front pad 6, pinion 9 and nut being assembled in succession rotor 2, then the component integration installed in portion loads, finally lock tensioned screw 13, whole installation process is very convenient, time saving and energy saving.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
