Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of drive plate structures. BACKGROUND

[0002] Drive plate is one of the most widely used components in mechanical field, and drive plate is widely used in mine machinery, heavy vehicle transmission system, industrial gear box and other scenes.As a transmission component, drive plate has to bear complex load in working process, which leads to its more prone to wear, cracking and other damage conditions.For the damage of drive plate, the traditional processing method and the defects of each are as follows:

[0003] 1, the damaged position of drive plate is repaired by surfacing: heat input leads to deformation of drive plate, and secondary finishing is needed after surfacing repair.

[0004] 2, replace new drive plate: high cost, long equipment downtime.

[0005] 3, patch reinforcement is carried out at the damaged position of drive plate: the bonding strength of patch and drive plate is low, and the repaired drive plate is prone to fall off and has short service life. SUMMARY

[0006] The utility model solves the technical problems of the prior art, provides a kind of drive plate structure of convenient repair, and realizes the rapid repair of drive plate.

[0007] The utility model discloses the technical scheme adopted to solve the above problems: a kind of drive plate structure of convenient repair, characterized by: including body disc and flange plate, the circumferential step of the easy-wearing surface of the body disc is formed, the flange plate is covered on the circumferential step, flange plate covers easy-wearing surface completely, the opening structure on flange plate is consistent with the opening structure on easy-wearing surface, and flange plate and body disc are detachably assembled by fastener.

[0008] Preferably, the flange plate and the body disc are correspondingly provided with four screw holes distributed in cross, and the assembly of the flange plate and the body disc is realized by screwing bolts into the corresponding screw holes of the flange plate and the body disc.

[0009] Preferably, the flange plate has a circumferential machining allowance of 0.03mm.

[0010] Preferably, the radial width of the circumferential step is 3-4mm.

[0011] Compared with the prior art, the utility model discloses the advantages that the driving disc is designed as the compression mounting structure of the body disc and the flange disc from the integral structure, the flange disc is the wearing component of the driving disc, in the operation process, the wearing mainly occurs on the flange disc, after wearing, only need to replace the flange disc to realize the quick modification, and the repair procedure and the spare part replacement cost are saved. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is the structure schematic view of the driving disc in the utility model embodiment;

[0013] In the drawing, 1, the body disc, 2, the flange disc, 3 screw hole. DETAILED DESCRIPTION

[0014] The utility model is further described in detail below in combination with the drawings, and the embodiment is exemplary, and is intended to explain the utility model, and can not be understood as the limitation of the utility model.

[0015] For the repair of the driving disc, the application customizes the stepped flange disc structure, and combines the pre-tightening force assembly process, so that the size repair and the quick recovery of the mechanical property of the driving disc can be realized.

[0016] As Figure 1 Indicated, the driving disc structure of the embodiment includes the body disc 1 and the flange disc 2, the easy wearing surface of the body disc 1 is circumferentially formed into the circumferential step, the flange disc 2 is compression mounted on the circumferential step, the flange disc 2 completely covers the easy wearing surface, the opening structure on the flange disc 2 is consistent with the opening structure on the easy wearing surface, and the flange disc 2 is provided with four screw holes 3 corresponding to the body disc 1 in cross distribution to realize detachable assembly.

[0017] The radial width of the circumferential step is 3-4mm.

[0018] The flange disc material selects 16Mn, and the circumferential reserved machining interference amount is 0.03mm.

[0019] The flange disc is assembled by compression mounting, and the flange disc and the body disc are bolted in cross order three times to 100N·m.

[0020] 150 DEG C heat treatment 2 hours eliminate assembly stress.

[0021] The flange disc circumferential is processed to the standard size, and the detection runout value is 0.08mm.

[0022] 1, the driving disc using the structure, after replacing the flange disc repair, the driving disc radial runout is less than or equal to 0.1mm, and the transmission precision is recovered.

[0023] 2, after wearing, only replace the flange disc, and the declaration cost is reduced by 70%.

[0024] 3. The abnormal consumption of saw blade is reduced by 50% due to the wear of the driving disc.

[0025] 4. The overall replacement of the driving disc needs 5 hours, and the replacement of the flange plate only needs 1 hour, so that the replacement efficiency is greatly improved.

[0026] In addition to the above embodiments, the utility model also includes other implementation manners, and the technical solutions formed by using equivalent transformation or equivalent replacement should fall within the protection scope of the utility model claims.
