[0027] Reference Figure 1-4 The utility model provides an integrated gear chamber cover, comprising:
[0028] The main unit 100 includes a cover plate body 101, the cover plate body 101 is arranged on the engine body, a fixing assembly 102 is arranged on the back of the cover plate body 101, a transmission shaft positioning assembly 103 is arranged between the cover plate body 101 and the fixing assembly 102, the transmission shaft positioning assembly 103 is used to position the engine transmission shaft, and a limiting assembly for limiting the fixing assembly 102 is arranged on the back of the cover plate body 101;
[0029] The oil filter unit 200 includes an oil filter 201. A threaded connecting pipe 202 is provided on the right side of the cover body 101. The threaded connecting pipe 202 is connected to the oil filter 201. The other end of the threaded connecting pipe 202 is communicated with the inner side of the cover body 101. The oil filter 201 is a jx0506 type oil filter in the prior art, and impurities in the oil are adsorbed by the internal filter paper.
[0030] The transmission shaft positioning assembly 103 includes a mounting ring 103a, and an oil seal 103b is bonded to the inner ring of the mounting ring 103a, so that the oil is prevented from leaking out through the oil seal 103b.
[0031] Furthermore, the outer ring of the mounting ring 103a is provided with a plurality of arc-shaped notches, and the back side of the cover body 101 is provided with a mounting groove that matches the outer ring of the mounting ring 103a. The mounting ring 103a is fixed by installing it in the mounting groove to prevent the mounting ring 103a from colliding with the engine drive shaft due to the vibration of the engine running, thereby causing damage to the engine drive shaft or slowing down.
[0032] Furthermore, the fixing assembly 102 includes a mounting plate 102a, a through hole having the same position and size as the inner circle of the mounting ring 103a is opened on the front side of the mounting plate 102a, the mounting plate 102a is mounted on the back side of the cover body 101 by a plurality of bolts, a sleeve 102b is fixedly connected to the upper right side of the back side of the mounting plate 102a, and the mounting plate 102a clamps the mounting ring 103a between the mounting plate 102a and the cover body 101 to prevent the mounting ring 103a from moving radially along the engine drive shaft.
[0033] Furthermore, the limiting assembly includes a nut 104, which is fixedly connected to the back side of the cover body 101. The internal thread of the nut 104 is connected to a screw rod 104a. The end of the screw rod 104a away from the nut is rotatably connected to a limiting rod 104b. The limiting rod 104b is inserted into the interior of the sleeve 102b. The screw rod 104a drives the limiting rod 104b to move through the nut 104, so that the mounting plate 102a is laterally limited by the limiting rod 104b, thereby preventing the vibration during the operation of the engine from loosening the bolts and causing the mounting plate 102a to fall off.
[0034] Furthermore, the nut 104 is fixedly connected to a limiting spring 104c on one side close to the limiting rod 104b, and the other end of the limiting spring 104c is fixedly connected to the limiting rod 104b. The elastic force provided by the limiting spring 104c prevents the limiting rod 104b from moving back, thereby improving the limiting effect on the mounting plate 102a.
[0035] During use, when the oil seal 103b needs to be replaced, the cover body 101 is removed, and the screw 104a is rotated so that the screw 104a drives the limiting rod 104b to be withdrawn from the sleeve 102b. Then, the bolts on the mounting plate 102a are removed and the mounting plate 102a is removed. The mounting ring 103a is pulled out, and the oil seal 103b is taken out and a new oil seal 103b is installed with glue or other adhesives, thereby completing the replacement of the oil seal 103b, so that the entire cover body 101 is removed together to prevent the loss of parts during the disassembly process. The oil filter 201 can be replaced by unscrewing it from the threaded connecting pipe 202, thereby facilitating the maintenance of the gear chamber cover.
[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
