Description

Support frame for transmission shaft

Technical Field

The utility model relates to a support frame for transmission shaft.

Background

The gear shaft refers to a mechanical part which supports a rotating part and rotates together with the rotating part to transfer motion, torque or bending moment, the gear shaft is very commonly used in a transmission system of a ship and is welded on the transmission shaft through a gear, a workshop is generally finished through manual welding, the workshop lacks of a special support frame, during welding, the transmission shaft is not specially positioned and supported, the welding is inconvenient, meanwhile, the transmission performance of the gear shaft can be influenced by processing errors, the welding is serious, even products are scrapped, and loss is caused to ship enterprises.

SUMMERY OF THE UTILITY MODEL

To the weak point that exists in the above-mentioned problem, the utility model provides a support frame for transmission shaft.

In order to achieve the above object, the utility model provides a support frame for transmission shaft, including the base of tube-shape and connect soon the double-screw bolt in the base, the upper end of double-screw bolt is fixed with the flat board, the both sides of flat board are equipped with the riser, be equipped with first pitch arc and with the second pitch arc that first pitch arc links up on the face of riser, the camber of second pitch arc is less than first pitch arc, first running roller is established between two the risers, is located the intersection of second pitch arc and the upper edge of riser simultaneously, the riser is opened at the intersection of first pitch arc and second pitch arc has the spout, the slider can slide and locate in the spout, be equipped with the second running roller between the slider, the slider bottom fixedly connected with lift axle, the lift axle passes the flat board, and be equipped with pressure spring on the lift axle;

for a transmission shaft with a certain specification, the first roller and the second roller can simultaneously contact the circumferential surface of the transmission shaft to form stable four-point support through the extension and retraction of the compression spring, and meanwhile, the height of the transmission shaft is adjusted through the stud, so that the gear is very convenient to weld on the transmission shaft.

Preferably, a locking nut is arranged on the stud;

in the technical scheme, after the position of the stud is adjusted, the stud is locked through the locking nut, so that the support frame is stable in structure.

The utility model discloses beneficial effect for prior art does: the support frame height-adjustable that this scheme provided, the staff of being convenient for selects suitable support height, and the support frame forms four point through two sets of running rollers and supports, supports stably, has made things convenient for the welding of actual welder at the epaxial gear of transmission.

fig. 2 is a side view of a support frame for a transmission shaft according to the present invention;

fig. 3 is a schematic view of the transmission shaft arranged on the support frame.

In the figure: 1. a base; 2. a stud; 3. locking the nut; 4. a flat plate; 5. a vertical plate; 51. a first arc line; 52. a chute; 53. a second arc; 6. a lifting shaft; 7. pressing a spring; 8. a slider; 9. a second roller; 10. a first roller; 11. a drive shaft.

Detailed Description

As shown in fig. 1, fig. 2 and fig. 3, the utility model provides a support frame for transmission shaft, including base 1 of tube-shape and the double-screw bolt 2 of swivelling joint in base 1, the upper end of double-screw bolt 2 is fixed with flat board 4, the both sides of flat board 4 are equipped with riser 5, be equipped with first pitch arc 51 and the second pitch arc 53 that links up with first pitch arc 51 on the face of riser 5, the camber of second pitch arc 53 is less than first pitch arc 51, first running roller 10 is established between two riser 5, be located the intersection of second pitch arc 53 and the upper edge of riser 5 simultaneously, riser 5 is opened at the intersection of first pitch arc 51 with second pitch arc 53 has spout 52, slider 8 slidable locates in spout 52, be equipped with second running roller 9 between slider 8, slider 8 bottom fixedly connected with lift axle 6, lift axle 6 passes flat board 4, and be equipped with pressure spring 7 on lift axle 6; and a locking nut 3 is arranged on the stud 2 and used for fastening the height-adjusted stud 2.

The support frame height-adjustable that this scheme provided, the staff of being convenient for selects suitable support height, and the support frame forms four point through two sets of running rollers and supports, supports stably, has made things convenient for the welding of actual welder at the epaxial gear of transmission.

When in specific use, the utility model is described with the attached drawings for the convenience of understanding;

as shown in fig. 2, the size of the transmission shaft 11 is set to a standard size, when the transmission shaft 11 with the standard size is placed on the support frame, the first roller and the second roller form stable four-point support for the transmission shaft 11, when the size of the transmission shaft 11 is larger than the standard size, the compression spring can release elastic force to enable the second roller to ascend, and also plays a role of four-point support, when the size of the transmission shaft 11 is smaller than the standard size, the compression spring can further contract, and the transmission shaft 11 is also supported by the first roller and the second roller; within a certain size range, the transmission shaft 11 can be supported by four points, and the support is very stable.
