Description

A kind of volute spiral spring is installed isolated plant

Technical field

The utility model relates to volute spiral spring isolated plant is installed.

Background technology

Plane scroll spring is that the elongated band material of a kind of usefulness turns to the linear spring of snail; The distortion of material production flexural resilience, the number of turns is more, generally needs just can install after the rolling; Shown in the illustration 2 is the wherein parts of an operating mechanism in the gas-insulated switch (GIS); Have main shaft 11, main shaft handle 12, driven shaft 14, driven footstalk 15, connected by connecting rod 13 between main shaft handle 12 and the driven footstalk 15, dish has plane scroll spring 17 on driven shaft 14; The inner end of plane scroll spring 17 is connected on the driven shaft 14, and the outer end is fixed on the joint 18 of mechanism.In fitting process, only after volute spiral spring 17 rollings, connecting rod 13 and driven footstalk 15 ability pin joints are accomplished assembling.Because assembly space is less, the rolling of manual operation volute spiral spring is very inconvenient.

The utility model content

The purpose of the utility model is to propose for plane scroll spring a kind of volute spiral spring of providing convenience to be installed isolated plant is installed.

For achieving the above object, the utility model is taked following technical scheme: this volute spiral spring is installed isolated plant, has casing; Respectively be provided with axis hole on the front and back walls of casing, corresponding axis hole is fixed with Connection Block on the antetheca of casing, is fixed with sleeve pipe on the Connection Block; Tube chamber on axis hole on the casing, the axis hole of Connection Block and the sleeve pipe is in the same center line, and is provided with worm couple in the casing, and worm-wheel shaft is by the bearing supporting that is in respectively on the casing front and back walls; One end of worm-wheel shaft stretches out from the antetheca axis hole; Be provided with axle drive shaft in the sleeve pipe, be connected by joint between worm-wheel shaft and the axle drive shaft, the end that said axle drive shaft stretches out sleeve pipe is a sphenocephaly.

Said axle drive shaft is provided with annular spacing groove, and the annular spacing groove of respective drive is provided with two relative spacing tapped bore on the outer peripheral face of sleeve pipe, respectively is provided with stop screw in the spacing tapped bore.

The utility model utilizes the worm drive principle, so laborsaving saving time, the utility model is simple in structure, easy to use.

The specific embodiment

Embodiment

A kind of volute spiral spring is installed isolated plant; Has casing 1; The front and back walls 1-1 of casing 1, the last axis hole that respectively is provided with of 1-2; The antetheca 1-1 of casing 1 goes up corresponding axis hole and is fixed with Connection Block 2, is fixed with sleeve pipe 3 on the Connection Block 2, and the axis hole of the axis hole on the casing 1, Connection Block 2 and the tube chamber on the sleeve pipe 3 are in the same center line.Be provided with worm couple 4 in the casing 1, comprise worm gear 4-1 and worm screw 4-2.Worm-wheel shaft 4-3 inserts in the axis hole of casing antetheca 1-1 and rear wall 1-2 through front bearing 5-1 and rear bearing 5-2.Axle 4-4 one end of worm screw 4-2 stretches out casing 1.In casing 1 and be in the axis hole of antetheca and be fixed with bearing seat 9, front bearing 5-1 is fixed in the bearing seat 9.The end of worm-wheel shaft 4-3 stretches out from antetheca 1-1 axis hole, is provided with axle drive shaft 6 in the sleeve pipe 3, is connected by joint 7 between worm-wheel shaft 4-3 and the axle drive shaft 6, and the end that said axle drive shaft 6 stretches out sleeve pipe 3 is sphenocephaly 6-1.

Said axle drive shaft 6 is provided with annular spacing groove 6-2, and the annular spacing groove 6-2 of respective drive 6 is provided with two relative spacing tapped bore on the outer peripheral face of sleeve pipe 3, respectively is provided with stop screw 8 in the spacing tapped bore.

When this device used, the sphenocephaly 6-1 of axle drive shaft 6 inserted among the bar groove 14-1 on driven shaft 14 end faces among Fig. 2, and worm screw 4-2 rotation drives worm gear 4-1 rotation, and then drove axle drive shaft 6 rotations, like a cork volute spiral spring was carried out rolling.
