In order to achieve the above object, the technical solution adopted in the utility model is, this utility model provides one Planer milling machine actuating unit, including servomotor and the decelerator that is connected with servomotor power end, Described decelerator has driving box away from one end connection of servomotor, sets between described servomotor and decelerator Being equipped with shaft coupling, described shaft coupling is miniature elastic diaphragm coupling.

As preferably, described decelerator is large speed ratio decelerator.

As preferably, the output shaft of described decelerator is hollow axle.

As preferably, it is connected by expansion sleeve between described servomotor and shaft coupling.

As preferably, it is connected by expansion sleeve between described decelerator and driving box.

Compared with prior art, advantage of the present utility model and good effect are,

1, this utility model is by adding miniature elastic diaphragm coupling between servomotor and decelerator, profit By the feature of miniature elastic diaphragm coupling, effectively raise planer milling machine power transmission agility, Make equipment response sensitive, moment of torsion is powerful and can abatement apparatus creeping phenomenon in running, meanwhile, this Utility model is reasonable in design, simple in construction, with low cost.

Detailed description of the invention

In order to be more clearly understood that above-mentioned purpose of the present utility model, feature and advantage, below in conjunction with attached This utility model is described further by figure and embodiment.It should be noted that in the case of not conflicting, Feature in embodiments herein and embodiment can be mutually combined.

Elaborate a lot of detail in the following description so that fully understanding this utility model, but, This utility model can be different from other modes described here with employing to be implemented, therefore, and this utility model It is not limited to the restriction of the specific embodiment of description described below.

Embodiment 1, as it is shown in figure 1, the present embodiment provides a kind of planer milling machine actuating unit, including Servomotor 1 and the decelerator 2 being connected with servomotor 1 power end, decelerator 2 is away from servomotor 1 One end connect have driving box 4, be provided with shaft coupling 3, shaft coupling 3 between servomotor 1 and decelerator 2 For miniature elastic diaphragm coupling, miniature elastic diaphragm coupling is selected to be based primarily upon two purposes, a mesh Be reduce planer milling machine actuating unit volume；Two is effectively to utilize miniature elastic diaphragm coupling Characteristic, miniature elastic diaphragm coupling is relative to common shaft coupling, and its volume is the least, and need not moisten Sliding, structure is compacter, and intensity is high, and service life is long, without spin gap, is not affected by temperature and greasy dirt, have acidproof, Feature alkaline-resisting, etch-proof, relatively simple for structure, be convenient to mount and dismount, it is adaptable to high temperature, at a high speed, have corrosion be situated between The axle system transmission of matter work condition environment. the connection of flexible member is very close to each other, is typically not required to lubrication, easy to maintenance, Balance is easily, lightweight, noiseless, and relatively strong to environmental suitability, reliability is high, and carrying is big, and efficiency is high, Service life length but the elasticity of torsion is relatively low, buffer shock-absorbing poor performance, be mainly used in load ratio relatively smoothly in, High-speed rotation axle system.Two axle relative displacements can be compensated, acidproof, corrosion-resistant, it is allowed to operating temperature reaches 200 degree. Can partly replace gear coupling, compare with gear coupling, the most relatively slide, these all characteristics, Can preferably be applied on planer milling machine, it is ensured that its power transmits agility, makes equipment response spirit Quick, moment of torsion is powerful and can abatement apparatus creeping phenomenon in running, specifically, in the present embodiment, Select the miniature elastic diaphragm coupling that model is AM58S12/4096PB-10 that Germany LIKA produces.

Equally, also for reducing volume and improving the efficiency of decelerator, in the present embodiment, decelerator 2 is Large speed ratio decelerator, in the present embodiment, decelerator 2 selects brand to be that Shanghai promise is wide, and model is K157 Cone gear reducer, this decelerator has volume compact, simple in construction, and transmission efficiency is higher, transmission The advantages such as power is relatively big, stable movement.

The output shaft of decelerator 2 and driving box 4 is fixing for convenience, in the present embodiment, and decelerator 2 Output shaft be hollow axle, equally, in order to improve transmission efficiency, in this embodiment, servomotor 1 defeated Go out and all (figure is not shown by expansion sleeve between end and shaft coupling 3, the output shaft of decelerator 2 and driving box 4 Go out) connect.

The above, be only preferred embodiment of the present utility model, is not that this utility model is made it The restriction of its form, any those skilled in the art possibly also with the disclosure above technology contents in addition Change or be modified as the Equivalent embodiments of equivalent variations and be applied to other field, but every without departing from this practicality New technique plan content, according to technical spirit of the present utility model above example is made any simply Amendment, equivalent variations and remodeling, still fall within the protection domain of technical solutions of the utility model.
