Abstract
A kind of grass trimmer transmission holder structure, including pedestal, pedestal one end are power intake, the other end is power output end, and pedestal is equipped with bearing between power intake and power output end, it is characterised in that：The pedestal is nylon material, and pedestal inner hole wall integrated injection molding is formed with annular groove, and bearing is as inserts, in annular groove.The utility model provides a kind of grass trimmer transmission holder structure, and using nylon material as retainer, bearing is mounted on retainer by way of integrated injection molding, reduces assembly and process costs, and overall quality is lighter as insert structure.
Description
Technical field
The utility model is related to using gasoline engine or lithium electricity as the hand-held hay mover technical field of power, refer in particular to a kind of mowing
Machine is driven holder structure.
Background technology
Common hand-held hay mover, either gasoline engine or lithium electricity are power, are required for a very long transmission shaft
(1.2-1.5m or so) by power transmission to cutting part, the blade on cutting attachment is transmitted axis and drives high speed rotation, to reach
To the purpose of mowing.For the output end of transmission shaft there are one retainer, he is a slight interference pressing bearing using Al-alloy parts as ontology
Mechanism.Purpose, which is support transmission shaft, steady high speed rotation, the power exported in this way just not to be had too under minimum drag
Big process mechanical loss.
But there are following two drawbacks for the prior art：
1, of high cost.Aluminium alloy blank needs casting forming, then also need to the very high machining boring bearing hole of precision and
Circlip groove；It also needs to that bearing is pressed onto in bearing hole with special tooling after the completion；Baffle ring is packed into circlip groove, prevent bearing because
High-frequency vibration and withdraw.Such fitment material demand and technological requirement are all very high, and process time is also very long, so always
Body cost can be relatively high.
2, accessory weight.Aluminium alloy ontology determines that the construction weight will not be light, as hand-held tool, can influence very much to make again
Use comfort.
Utility model content
The purpose of this utility model is to provide a kind of grass trimmer transmission holder structure, using nylon material as retainer, axis
Make reduces assembly and process costs, and total constitution for insert structure mounted on retainer by way of integrated injection molding
Amount is lighter.
What the purpose of this utility model was realized in：A kind of grass trimmer is driven holder structure, including pedestal, pedestal one end are
Power intake, the other end are power output end, and pedestal is equipped with bearing between power intake and power output end, special
Sign is：The pedestal is nylon material, and pedestal inner hole wall integrated injection molding is formed with annular groove, and bearing is embedded in annular groove as inserts
It is interior.
Wherein, the bearing inner race is combined with transmission shaft, and annular flange and annular is respectively set in bearing both sides in transmission shaft
Card slot, annular slot coordinate baffle ring, baffle ring and annular flange to limit bearing inner race therebetween.
Wherein, the annular flange is arranged in power intake, and bearing is equipped with drive plate, drive plate in power intake
Back is resisted against annular flange outer end face.
Wherein, the bearing outer ring thickness is higher than annular groove depth.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1, by the technique of aluminium alloy compression casting → machining → pressing bearing → installation baffle ring, improve as using bearing as inserts,
Nylon material is directly molded.The aluminium alloy of same volume structure becomes nylon, eliminates machining and pressing bearing
Process procedure has also saved baffle ring this accessory, is cut down in cost very big.
2, since nylon is plastic part, density is less than aluminium alloy, so retainer overall weight reduces very much.
Description of the drawings
Fig. 1 is the transmission holder structure of the utility model；
Fig. 2 is the assembly structure figure of the utility model retainer and transmission parts；
Fig. 3 is existing aluminum alloy driving holder structure.
Reference numeral：1, pedestal；1a, annular groove；2, bearing；2a, inner ring；2b, outer ring；3, transmission shaft；3a, annular flange；
4, baffle ring；5, drive plate.
Specific implementation mode
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-3：
A kind of grass trimmer transmission holder structure, including pedestal 1,1 one end of pedestal are power intake, the other end is power output
End, pedestal 1 are equipped with bearing 2 between power intake and power output end, and the pedestal 1 is nylon material, 1 endoporus of pedestal
Wall integrated injection molding is formed with annular groove 1a, and bearing 2 is used as inserts, in annular groove 1a.Bearing 2 is used as inserts, is injection molding into transmission
Seat ontology, is so not necessarily to 4 anti-back of baffle ring.
Wherein, 2 inner ring 2a of the bearing is combined with transmission shaft 3, and annular flange 3 is respectively set in 2 both sides of bearing in transmission shaft 3
And annular slot, annular slot coordinate baffle ring 4, baffle ring 4 and annular flange 3 to limit 2 inner ring 2a of bearing therebetween.
Wherein, the annular flange 3 is arranged in power intake, and bearing 2 is equipped with drive plate 5 in power intake, passes
5 back of Moving plate is resisted against 3 outer end face of annular flange.
Wherein, 2 outer ring 2b thickness of the bearing is higher than annular groove 1a depth.When injection molding, company's side exposed face of bearing 2 will seal
Note allows bearing 2 to fail in order to avoid high-temperature liquid state nylon material penetrates into 2 ball region of bearing.2 outer ring 2b of bearing is slightly higher, facilitates sealing.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore：The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model
Within the scope of.
