Technical field
The utility model belongs to the technical field of electric actuator, and in particular, the utility model relates to a kind of final controlling element main shaft guide structure.
Background technique
Valve is widely used in every profession and trade, such as, in the various industrial pipelines such as the petrochemical industry effect such as pipeline dams, current limliting for providing; And electric actuator is for keying and the folding degree of regulating valve.The drive unit of final controlling element in the course of the work, if main shaft does not have guide structure, the main shaft of drive unit just can not move up and down (being pure rotation) so, the common employing of the main shaft of Vidacare corp in the prior art is six side's guide structures for this reason, this guide structure can play the leading role to main shaft, but six side's guide structures are owing to being sliding friction structure, in guiding, efficiency is not high, lose a lot of ouput forces, affected the final ouput force of driver.
Model utility content
In order to solve the above-mentioned technical problem existing in prior art, the purpose of this utility model is to provide a kind of easy to assembly, simple in structure, steady quality, the high final controlling element main shaft guide structure of guiding efficiency.
Final controlling element main shaft guide structure described in the utility model, comprises base plate, guide sleeve and main shaft; It is characterized in that: described plate upper surface has six square grooves, described base plate lower surface has the cylinder groove to downward-extension; Described guide sleeve has the hexagonal nuts coordinating with described six square grooves, and the cylinder coordinating with described cylinder groove, and has the central shaft hole that can hold described main shaft in the middle of described guide sleeve; The hexagonal nuts of described guide sleeve is assemblied on described six square grooves, and the cylinder of described guide sleeve and described cylinder groove assemble and extend certain distance from described cylinder groove bottom; Described spindle mounted is in the central shaft hole of described guide sleeve; And on the sidewall of described main shaft, there is the through hole that holds needle roller, in described through hole, be equipped with needle roller, the two ends of described needle roller are equipped with the bearing housing that can roll, and can hold the described bearing housing rolling groove of scroll-up/down therein and also have on the cylinder of described guide sleeve; And on described main shaft, be also provided with the guide sleeve locking nut that can lock described guide sleeve, described guide sleeve locking nut internal surface has internal thread, and the cylinder of described guide sleeve extends on the outer wall of cylinder groove and is provided with the outside thread that can match with the internal thread of described guide sleeve locking nut.
Wherein, near the upper end of described main shaft, there is trapezoidal thread.
Compared with prior art, final controlling element main shaft guide structure described in the utility model has following beneficial effect:
(1) simple in structure, guide effect is good: because this novel guide structure adopts rolling friction structure, it is configured in and on main shaft, is equipped with needle roller, and just can realize its function by guide sleeve locking nut and guide sleeve, this structure is relatively simple, and guiding efficiency is high, has promoted delivery efficiency, and using effect is better.
(2) easy to use, cost is low, efficiency is high: because this novel structure is simplified, manufacture assembly cost low, and fairly simple in production assembly process, there is special tooling crimping, be convenient to processing and produce assembling.In addition, be also convenient to field maintenance, improved production and maintenance efficiency.
(3) long service life: this novel guide structure is due to the character of its rolling friction, and its wear-out life is inevitable significantly to be promoted, and makes the extremely wear-resisting of guide structure change, can increase substantially the working life of product.
Brief description of the drawings
Fig. 1 is final controlling element main shaft guide structure schematic diagram described in embodiment 1.
Embodiment
