Detailed Description

An embodiment of a gearbox configuration for ease of maintenance according to the present invention is further described with reference to fig. 1 through 3.

See fig. 1, a gear box structure convenient to maintenance, including box 1, the top of box 1 is equipped with case lid 4, is connected through the mounting between case lid 4 and the box 1. Utilize the mounting to fix case lid 4 and box 1, replace the bolt to be connected between case lid 4 and the box 1, when the gear box internals takes place to damage, the setting of mounting is convenient for the dismantlement between case lid 4 and the box 1, the maintenance of the gear box of being convenient for.

Referring to fig. 1 and 2, the fixing member includes four inserts and four grooves 7, the inserts and the grooves 7 form a limiting fit, the four inserts are fixedly mounted at four corners of one side of the box cover 4 close to the box body 1, the grooves 7 are located at one side of the box body 1 close to the fixing sleeve 5, and the grooves 7 can be just used for the fixing sleeve 5 to be placed in. When the box cover 4 and the box body 1 need to be connected, the plug-in is inserted into the groove 7, and the box cover 4 and the box body 1 are firmly connected because the plug-in and the groove 7 form limiting fit.

See fig. 1 and 3, the plug-in components include fixed cover 5, and one side that case lid 4 was kept away from to fixed cover 5 is open structure, the inner chamber sliding connection of fixed cover 5 has fixture block 9, and fixture block 9 is located fixed cover 5 and keeps away from one side at case lid 4 center, fixture block 9 is the slope structure, fixture block 9 passes through the elastic component and is connected with fixed cover 5 inner chamber, the first draw-in groove that supplies fixture block 9 to put into is seted up to the inner chamber of box 1, first draw-in groove link up with recess 7, the inside sliding connection of first draw-in groove has movable rod 6, and be located and connect through connecting plate 2 between the movable rod 6 of homonymy. When sliding fixed cover 5 to one side of recess 7, because the elastic action of elastic component, and the slope structure of fixture block 9, fixture block 9 removes to one side of elastic component, when fixed cover 5 is whole to be located the inside of recess 7, because the elastic action of elastic component, fixture block 9 card is in the inside of first draw-in groove, fixed cover 5 at this moment is fixed in the inside of recess 7, then it is fixed firm between box 1 and the case lid 4, when needs are dismantled box 1 and case lid 4, promote connecting plate 2 to the one side of keeping away from standing groove 3, movable rod 6 extrudees fixture block 9 this moment, make fixture block 9 follow the inside roll-off of first draw-in groove, then box 1 takes place the separation with case lid 4.

See fig. 2 and 3, the elastic component is spring 8, and spring 8 is located the inside of fixed cover 5, and fixture block 9 is located the rectangular 11 of the inside one end fixedly connected with of fixed cover 5, and the width value of rectangular 11 is greater than the width value of fixture block 9, and the one end of spring 8 contacts with the inner chamber of fixed cover 5, and the other end and the rectangular 11 contact of spring 8, and all be connected through the connecting piece between spring 8 and rectangular 11 and the inner chamber of fixed cover 5. The strip 11 has a limiting function on the fixture block 9, so that the fixture block 9 is prevented from being separated from the fixed sleeve 5, and the elasticity of the spring 8 is better.

Referring to fig. 2 and 3, a placing groove 3 is formed in the inner cavity of the box body 1, and the connecting plate 2 is located inside the placing groove 3. The standing groove 3 plays the effect of injecing to connecting plate 2, avoids connecting plate 2 to expose outside, when colliding connecting plate 2 by accident, causes to take place the separation between box 1 and the case lid 4.

Referring to fig. 2 and 3, the connecting piece includes picture peg 10, and picture peg 10 fixed mounting is at the both ends of spring 8, and the both ends of picture peg 10 all are equipped with protrudingly, and all set up the second draw-in groove 13 that supplies picture peg 10 both ends jut to place on rectangular 11 and the fixed cover 5, and the fixed cover 5 is kept away from one side of case lid 4 and is articulated to have apron 12. When the spring 8 is compressed a certain number of times, the elasticity of the spring 8 becomes small. At this moment, the spring 8 is replaced, the cover plate 12 is opened, the spring 8 is taken out from the inside of the fixed sleeve 5, a new spring 8 is replaced, the protruding parts on the spiles 10 on the two sides of the spring 8 are inserted into the second clamping grooves 13 formed in the fixed sleeve 5 and the strip 11 at this moment, the cover plate 12 is covered, and then the spring 8 is fixed and firm with the fixed sleeve 5 and the strip 11.

The working principle is as follows: after the gear box is firmly installed, the box body 1 and the box cover 4 are firmly fixed, when the internal parts of the gear box are damaged, the box cover 4 is detached from the box body 1, the connecting plate 2 is pushed to the bottom of the placing groove 3, the movable rod 6 pushes the side where the clamping block 9 is located, the clamping block 9 slides out from the inside of the first clamping groove, the box body 1 is separated from the box cover 4 at the moment, when the internal parts of the gear box are repaired and the box body 1 and the box cover 4 need to be firmly fixed, the fixing sleeve 5 is inserted into the groove 7, due to the elastic action of the spring 8, the fixture block 9 slides towards the side where the spring 8 is located, finally the fixture block 9 is clamped into the first clamping groove, the box body 1 and the box cover 4 are firmly fixed at the moment, when the spring 8 needs to be maintained, the cover plate 12 is opened, the spring 8 is taken out from the inner cavity of the fixed sleeve 5, a new spring 8 is replaced, and the cover plate 12 is covered.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the utility model may occur to those skilled in the art without departing from the principle of the utility model, and are considered to be within the scope of the utility model.
