Abstract
The utility model relates to a clutch, in particular to a closed wet friction clutch, which comprises a friction disk component, a pressure adjustment component, a spline shaft, and a frictional clutch housing. The utility model is characterized in that: the fictional clutch housing is a closed body; an inner friction disc is arranged on the spline shaft; the excircle salient of outer friction disc fixed on the spline shaft is matched with the longitudinal groove of the fictional clutch housing; the spline shaft is arranged in the fictional clutch housing supported by the bearing; no less than one end of the spline shaft extends out of the fictional clutch housing. The utility model has the advantages of not being effected by the environment, having excellent friction disk heat dissipating performance, possessing long life performance, and having good comprehensive dynamic performance, which is more particularly suitable for coal equipments.
Description
Technical field
The utility model relates to a kind of clutch, particularly enclosed immersion oil friction clutch.
Background technique
Friction clutch is one of parts commonly used in the machinery, and it is to come carry-over moment by the frictional force between the interior outside friction disc, and the size of moment is to adjust assembly by pressure to adjust.Usually the shell of friction clutch is non-sealing; so in the open or the bigger occasion of dust when using; friction plate directly contacts with air; behind corrosive gas and the dust engaging friction sheet; default transmitting torque will reduce; for guaranteeing the proper functioning of clutch; need are bigger with the preset torque setting; will reduce the protective value of transmission system like this, and under overload or other improper situation, when friction clutch skids; heating value is very big; and this part heat can only dispel the heat by partial radiation, and friction plate easily is very easy to wearing and tearing, and this just needs often to change clutch.
Summary of the invention
That the purpose of this utility model provides is not affected by environment, the enclosed immersion oil friction clutch of long service life.
For achieving the above object, the technical solution of the utility model is: a kind of enclosed immersion oil friction clutch, comprise friction plate assembly, pressure adjustment assembly, splined shaft, friction clutch shell, it is characterized in that the friction clutch shell is an enclosing housing, interior friction plate is installed on the splined shaft, match with supporting cylindrical projection that is installed in the outside friction disc on the splined shaft of interior friction plate and cannelure in the friction clutch shell, splined shaft is bearing in the friction clutch shell by bearing, and at least one end of splined shaft stretches out the friction clutch shell.
Above-mentioned splined shaft is made up of central shaft and the external tooth cover that is enclosed within on the central shaft, is connected by key between external tooth cover and the central shaft, and the cylindrical of external tooth cover is the spline that matches with interior friction plate, and an axial attachment hole is arranged on the central shaft.
Above-mentioned pressure adjustment assembly is made up of thrust disc, plate-like adjusting nut and locking nut that order is installed on the splined shaft, is fixed with pressure spring between thrust disc and plate-like adjusting nut two opposing sides.
Above-mentioned pressure spring is made up of the pressure spring more than three that is distributed between thrust disc and plate-like adjusting nut two opposing sides.
The utlity model has following effect:
1, because the friction clutch shell is an enclosing housing, lubricant oil is housed in housing, thus between the interior outside friction disc when contact for mix or boundary friction lubricated, friction plate does not almost have wearing and tearing, long service life.
2, because friction plate has been accelerated flowing of liquid oils when rotating, make amount of localized heat be diffused into whole clutch housing rapidly, by housing heat loss through radiation, perfect heat-dissipating.
3,, be fit to very much coal equipment and use because friction plate is immersed in the fluid of seal casinghousing, and all gases of inside and outside environment, dust have no effect to the preliminary adjustment moment of torsion, so dynamic characteristic is good, and operation process need not adjusted moment of torsion.

Specific embodiment
As shown in Figure 1, in the friction clutch shell 8 of sealing, by bearing 3 supportings one splined shaft is installed, between splined shaft and the friction clutch shell seal arrangement 2 is installed, splined shaft is made up of central shaft 1 and the external tooth cover 9 that is enclosed within on the central shaft, be connected by key 10 between external tooth cover and the central shaft, the cylindrical of external tooth cover is the spline that matches with interior friction plate 5, at least one end of central shaft stretches out the friction clutch shell, stretch out on the central shaft of friction clutch shell an axial attachment hole 16 is arranged, the external reducer input shaft of this Kong Keyu links to each other, and has keyway 17 in this hole.Match with supporting cylindrical projection that is installed in the outside friction disc 6 on the splined shaft of interior friction plate and cannelure in the friction clutch shell.The pressure adjustment assembly that is installed on the external tooth cover is made up of thrust disc 11, plate-like adjusting nut 13 and the locking nut 15 of order installation, between thrust disc and plate-like adjusting nut two opposing sides, be fixed with pressure spring 12, pressure spring is made up of 6 independently little pressure springs that are distributed between thrust disc and plate-like adjusting nut two opposing sides, size according to clutch, the quantity of uniform pressure spring changes, and the purpose of pressure spring is to make the contact pressure of friction plate even.For guaranteeing the relative position relation between thrust disc and the plate-like adjusting nut, between thrust disc and plate-like adjusting nut, be evenly equipped with bolt 14 vertically.Put at external tooth and to adjust the relative the other end of assembly with pressure and be equipped with and be used to the positioning disk 4 that bears inside and outside friction plate axial force and play the role of positioning.On the relative side of friction clutch shell 8 of sealing, a flange plate 7 is arranged, can link to each other with input device by flange plate with the central shaft external part.
