Description
Technical field
The utility model relates to ocean linear actuator technical field, particularly relates to the motor cover of a kind of ocean linear actuator.
Background technology
In many applications, actuator ratio machinery and hydraulic system are advantageously.Actuator has independent self-sufficiency, firm, durable feature, is highly suitable for promoting load, reduces, pushes away, draws, rotates or positioning action.
Ocean linear actuator can for seat, hatch, fire resistant doorsets, lifesaving appliance, valve and throttle etc. on ship, naval vessels and boring tower.The motor cover of ocean linear actuator, as the vitals of linear actuator, be mainly used in protecting motor, but existing motor cover does not often have radiator structure, causes its radiating effect poor.
Utility model content
The technical problem that one, will solve
The purpose of this utility model is for the problems referred to above existing for prior art, spy provides the motor cover of a kind of ocean linear actuator, there is good radiating effect, do not possess with the motor cover overcoming ocean linear actuator in prior art the defect that radiator structure causes its radiating effect difference.
Two, technical scheme
For solving the problems of the technologies described above, the utility model provides the motor cover of a kind of ocean linear actuator, and described motor cover comprises lid and is arranged on the connection end cap of described lid end; Described connection end cap is connected with the bonnet with cavity, described bonnet is communicated with the described end cap that connects, on the outer surface of described bonnet, annular is evenly equipped with some fin, described fin is arcuation, and extend to described connection end cap end in the mode that the size of cross section increases progressively gradually from the end of described bonnet, form spiral duct between two adjacent described fin, described spiral duct is connected end cap by the air inlet being positioned at described connection end cap end with this and is communicated with.
Wherein, in the motor cover of above-mentioned ocean linear actuator, described fin is formed with away from the side of described bonnet the radiator structure increasing its area of dissipation.
Wherein, in the motor cover of above-mentioned ocean linear actuator, described radiator structure is jagged breach.
Wherein, in the motor cover of above-mentioned ocean linear actuator, on the outer surface that all described fin cover in the rear according to identical radian directional spreding.
Wherein, in the motor cover of above-mentioned ocean linear actuator, described lid is provided with mounting groove away from one end of described connection end cap.
Wherein, in the motor cover of above-mentioned ocean linear actuator, in described mounting groove, have multiple closure gasket groove loaded for sealing ring.
Three, the beneficial effects of the utility model
Compared with prior art, the motor cover of a kind of ocean of the present utility model linear actuator, on the outer surface of bonnet, annular is evenly equipped with some fin, the mode that this fin increases progressively gradually with the size of cross section extends to connection end cap end from the end of bonnet, and form spiral duct between adjacent two fin, spiral duct is by being positioned at the air inlet that connects end cap end and being connected end cap and being communicated with, because the draft loss of spiral wind is little, make air passage rates fast, improve radiating efficiency; In addition, the side of fin has jagged gap structure, adds the contact area of fin and air, good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the motor cover of the ocean linear actuator of the utility model embodiment;
Fig. 2 is the structural representation of lid in Fig. 1;
Fig. 3 is the A portion enlarged drawing in Fig. 1;
Wherein:
1 is lid, and 2 for connecting end cap, and 3 is bonnet, and 4 is fin, and 5 is spiral duct, and 6 is air inlet, and 7 is breach, and 8 is mounting groove, and 9 is closure gasket groove.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but can not be used for limiting scope of the present utility model.
The structure of the motor cover of the ocean linear actuator in the utility model embodiment as shown in Figure 1 to Figure 3, comprise lid 1 and the connection end cap 2 being arranged on lid 1 end, connect end cap 2 and be connected with the bonnet 3 with cavity, bonnet 3 with connect end cap 2 and be communicated with, on the outer surface of bonnet 3, annular is evenly equipped with some fin 4, fin 4 is in arcuation, and extend to connection end cap 3 end in the mode that the size of cross section increases progressively gradually from the end of bonnet 3, the mechanism that arranges like this has saved space, due to the fin the closer to connection end cap 2, its temperature can be higher, so its size is set to maximum, and it is set to reduced size away from the part connecting end cap 2.All fin 4 according to identical radian directional spreding on the outer surface of bonnet 3, make to form spiral duct 5 between two adjacent fin 4, spiral duct 5 is connected end cap 2 by the air inlet 6 being positioned at connection end cap 2 end with this and is communicated with, because the draft loss of spiral wind is little, make air passage rates fast, improve radiating efficiency.
Further, in the present embodiment, fin 4 is formed with away from the side of bonnet 3 radiator structure increasing its area of dissipation, and such as, radiator structure is jagged breach 7.Which increase the contact area of fin and air, good heat dissipation effect.
Lid 1 in the present embodiment is provided with mounting groove 8 away from the one end connecting end cap 2, has multiple closure gasket groove 9 loaded for sealing ring in this mounting groove 8.By mounting groove 8 and closure gasket groove 9, lid 1 is external on the Connection Block of motor cover.
As mentioned above, the motor cover of a kind of ocean of the present utility model linear actuator, on the outer surface of bonnet, annular is evenly equipped with some fin, the mode that this fin increases progressively gradually with the size of cross section extends to connection end cap end from the end of bonnet, and forming spiral duct between adjacent two fin, spiral duct is by being positioned at the air inlet that connects end cap end and being connected end cap and being communicated with, because the draft loss of spiral wind is little, make air passage rates fast, improve radiating efficiency; In addition, the side of fin has jagged gap structure, adds the contact area of fin and air, good heat dissipation effect.
Below be only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
