Abstract
The utility model discloses a novel coupling with backstopping function, comprising a coupling made up of two half-couplings by assembly and connection, wherein one half-coupling is provided with a backstopping clutch thereon. The backstopping clutch is a wedge block type backstop, and the coupling is a gear type coupling. The inner part of a shaft end hole of the backstop is connected with a driven shaft through an expansion bush and a double flat key; and the inner part of the other half-coupling is connected with a driving shaft through transitional fit. The coupling has the backstopping function.
Description
Technical field
The utility model relates to a kind of novel coupler.
Background technique
Coupling belongs to mechanical spare part in common use category, and coupling is made up of two halves, connects with driving shaft and driven shaft respectively.Two axles (driving shaft and driven shaft) that are used for connecting in the different institutions make it the mechanical parts of common rotation with transmitting torque, and in the power transmission of high-speed overload, it is the effect of dynamic performance that coupling also has buffering, vibration damping and raising axle.But in the middle of different workplaces, not only need transmitting torque between two element parts, also need to control sense of rotation, prevent the equipment reversing.For example in mine mechanism, the wire rope traction rubber conveyer is to make driving component by wire rope, and adhesive tape is made bearing carrier, and wire rope drags operation by driving wheel, and the wheel shaft two ends of driving wheel are connected with power source by coupling; Adhesive tape contacts with steel cable by the wedge type ear groove of both sides, is dragged by friction; Because the wire rope traction rubber conveyer possesses the fortune coal and takes advantage of people's two-fold advantage, so be widely used in taking advantage of in the double requirements of people and fortune coal.Mostly this kind equipment place to use is inclined shaft, and disk type braker only is installed, and anti kickback attachment is not installed; And the retarder that it uses is plane table thermoconductivity meter, input shaft and output shaft are only arranged, there is not unnecessary axle that non-return device is installed, there are not other reasonably anti-reversing measures yet, according to new " safety regulations in coal mine " (2006 editions), the essential anti-reverse-rotation device of installing of the upper conveying belt type conveyer that uses in the gradient tunnel, such wire rope traction rubber conveyer exists serious potential safety hazard.Therefore the accident that the wire rope traction rubber conveyer in running reversing took place once, causes casualties must install anti-reversing equipment additional.
The model utility content
The purpose of this utility model provides a kind of coupling with check function.
For achieving the above object, the utility model adopts following technological scheme: have the novel coupler of check function, comprise the coupling that is formed by connecting by the assembling of two half-couplings, one of them half-coupling is provided with non-return device.
Described non-return device is the wedge block type non-return device, and coupling is the gear type coupling.
In the stub bore of non-return device, be connected with driven shaft with two flat keys by expansion set; In second half coupling, be connected with driving shaft by transition fit.
The beneficial effects of the utility model are: when two driven shafts and driving shaft insert non-return device stomidium and second half coupling stomidium respectively, diaxon can normally rotate transmitting torque by the direction of setting, when an axle head reverses, the effect that just can be subjected to non-return device stops operating, in reliable delivery moment, realize the anti-reverse functions of check.Employing wedge block type non-return device and gear type coupling can guarantee the working life and the reliable sealing performance of non-return device, and be rational in infrastructure, long service life.The non-return device stomidium is connected with driven shaft with two flat keys by expansion set, and second half coupling hole and driving shaft are little Spielpassung, need not the heating assembling, has both protected check and sealability in the non-return device, and easy for installation again, the carry-over moment ability is strong.

Fig. 1 is a plan view of the present utility model;
Fig. 2 is a left view of the present utility model.
Embodiment
The novel coupler with check function as depicted in figs. 1 and 2 comprises gear coupling and wedge block type non-return device 1, gear coupling is formed by connecting by overcoat 4 assemblings by input gear shaft terminal 5 and output gear axle head 3, in output gear axle head 3 and 1 coaxial connection of non-return device, non-return device 1 and output gear axle head 3 become one after by two suitable conical surface sockets, fixedly connected with bolt 2, be connected with driven shaft 7 with two flat keys 8 by expansion set; In input gear shaft terminal 5, be connected with driving shaft 6 by transition fit.
During use, driving shaft 6 is connected with power source, moment of torsion can be passed to driven shaft 7 during normal operation, and when driven shaft 7 ends were subjected to excessive countertorque, the effect that will be subjected to non-return device 1 prevented reversing.For guaranteeing the working life and the reliable sealing performance of non-return device 1, non-return device 1 can adopt wedge type block low-speed big structural design, and bearing all adopts light and narrow series with sealing, and is rational in infrastructure, long service life.Certainly, the utility model is not limited to above structural type, and non-return device and coupling can adopt any kind.
