Description

TECHNICAL FIELD

[0001] The utility model relates to differential bearing technical field, concretely relates to a differential bearing cover subassembly. BACKGROUND

[0002] Bearing is an important part in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient in its movement process, and ensure its rotation accuracy. The early linear motion bearing form is to place a row of wooden rods under a row of pry plates. Modern linear motion bearings use the same working principle, but sometimes use balls instead of rollers. The simplest rotary bearing is a bushing bearing, which is just a bushing clamped between the wheel and the axle. This design is later replaced by rolling bearings, which use many cylindrical rollers instead of the original bushing, and each roller acts like a separate wheel.

[0003] The relationship between the differential and the bearing cover is very close. The bearing cover is a key component in the differential assembly, which directly affects the normal operation and service life of the differential. The differential has multiple bearings (such as differential housing bearings, half shaft bearings, etc.), which need to be firmly fixed on the differential housing. The bearing cover presses and fixes the bearing in the correct position through bolts or other means, ensuring that the bearing will not shift due to vibration or stress.

[0004] The inventor found in the process of realizing the utility model that:

[0005] Many bearings are used in existing differentials to fix the power output end, but the bearing cover structure of the differential bearing cover assembly is relatively simple at present. During installation, the bearing needs to be placed inside the base, then the upper cover body is placed on the bearing, and the upper cover body is pressed tightly by a hydraulic machine or manually, so that the bearing is installed in the base. However, the lubricant wrapped around the bearing and smeared inside the device will be squeezed out during the extrusion process, causing the lubricant to be consumed after a long period of use, resulting in wear and tear inside the differential, affecting the service life of the differential. At the same time, the existing differential bearing cover assembly needs to consume a lot of time and effort to disassemble the entire assembly when disassembling and adding lubricant, which makes it inconvenient to supplement the lubricant. SUMMARY

[0006] In order to solve the problem that the existing differential bearing cover assembly is pressed by hydraulic pressure, and a lot of time and effort is needed to disassemble the entire assembly, which makes it inconvenient to supplement the lubricant, the utility model puts forward a differential bearing cover assembly.

[0007] The utility model discloses a technical scheme for a differential bearing cover assembly, which comprises a base, a bearing installed inside the base, an oil storage groove formed in the base, a sealing ring fixedly connected to one side of the base, a connecting cover body installed inside the sealing ring, and an upper cover body installed outside the connecting cover body.

[0008] When the device needs to be installed, the bearing is first placed inside the base, then the connecting cover body is inserted into the sealing ring, and then the base, the connecting cover, and the sealing ring are pressed together. At this time, the lubricant can be filled through the cylindrical groove, and the lubricant flows into the oil storage groove through the cylindrical groove. Then, the upper cover body is installed on one side of the connecting cover body to fix the connecting cover body, ensuring good sealing and stability. This allows the device to store more lubricant in the oil storage groove during installation, and only the upper cover body needs to be removed when adding lubricant. The filling of the lubricant through the cylindrical groove ensures that the lubricant enters the oil storage groove. During use, the lubricant continuously flows out of the oil storage groove to lubricate the bearing, ensuring smooth operation of the bearing, reducing friction and wear, and improving the working efficiency of the differential.

[0009] Further improvement of the above technical scheme is that the lubricating structure comprises a plurality of injection pipes fixedly connected to the outer surface of the connecting cover body, the injection pipes are matched with the cylindrical groove in shape, and a plurality of sealing plates are fixedly connected to the outer surface of the upper cover body.

[0010] By adopting the above technical scheme, the injection pipes and the cylindrical groove are precisely connected to provide a channel for the smooth introduction of the lubricant, and the installation of the connecting cover body is limited to make the installation more stable and convenient. When injecting the lubricant, the operator only needs to inject an appropriate amount of lubricant into the injection pipe, and the lubricant can flow smoothly into the oil storage groove along the cylindrical groove.

[0011] Further improvement of the above technical scheme is that the sealing plate is fixedly connected to a filling seat on one side, the filling seat is conical and cylindrical, and the size of the filling seat is matched with the injection pipe.

[0012] By adopting the above technical scheme, the upper cover body is installed on one side of the connecting cover body, and the filling seat is inserted into the injection pipe to seal the injection pipe. This design not only simplifies the lubricant adding process, but also effectively avoids the leakage problem of the lubricant during the adding process.

[0013] Further improvement of the above technical scheme is that a permeation ring groove is formed in the base, a plurality of liquid outlet holes are formed in the permeation ring groove, and the liquid outlet holes are in communication with the oil storage groove.

[0014] By adopting the technical scheme, the oil tank continuously flows the lubricant into the penetration ring groove through the liquid outlet hole, and then the lubricant is evenly infiltrated outside the bearing through the penetration ring groove.

[0015] Further improvement of the above technical scheme is that a plurality of connecting grooves are arranged inside the base, and the connecting grooves are cross-distributed with the penetration ring groove.

[0016] By adopting the above technical scheme, the lubricant can be evenly distributed in the oil tank through the cross-distribution design of the penetration ring groove and the connecting groove.

[0017] Further improvement of the above technical scheme is that a plurality of split arc plates are fixedly connected to one side of the filling seat, and a movable groove is arranged between the two split arc plates.

[0018] By adopting the above technical scheme, when the filling seat is inserted into the injection pipe, the split arc plate is elastically expanded through the movable groove, so that the filling seat can be quickly inserted into the injection pipe, and after the filling seat is completely inserted, the split arc plate is tightly attached to the inner wall of the injection pipe.

[0019] Further improvement of the above technical scheme is that a snap ring is fixedly connected inside the injection pipe, the end of the split arc plate is a tapered plate, the diameter of the snap ring is larger than the diameter of the tapered plate, and a clamping groove is arranged on the outer surface of the split arc plate, and the shape of the clamping groove is matched with the snap ring.

[0020] By adopting the above technical scheme, the tapered plate is gradually retracted into the movable groove under the extrusion of the inner wall of the injection pipe, which increases the friction between the split arc plate and the injection pipe, so that the upper cover body is more stable during installation, and the split arc plate is fixed by clamping the snap ring into the clamping groove, so as to prevent it from falling off from the injection pipe.

[0021] Further improvement of the above technical scheme is that a plurality of insertion plates are fixedly connected to one side of the upper cover body, a plurality of insertion grooves are arranged on the outer surface of the connecting cover body, and the shapes of the insertion plates and the insertion grooves are matched.

[0022] By adopting the above technical scheme, the connection between the upper cover body and the connecting cover body is more closely connected through the cooperation of the insertion plate and the insertion groove, which simplifies the installation steps and improves the assembly efficiency.

[0023] Beneficial effect: when the lubricant needs to be injected, only appropriate lubricant is added into the injection pipe, which will flow into the oil storage groove along the cylindrical groove, then the upper cover body is installed, and the injection pipe is sealed with the filling seat, the design simplifies the lubricant adding process, prevents leakage, and allows the upper cover body to be disassembled to supplement the lubricant, during use, the oil storage groove continuously supplies oil to the infiltration ring groove through the liquid outlet hole, the lubricant uniformly infiltrates the outside of the bearing, and the infiltration ring groove and the connecting groove are cross-distributed to ensure that the lubricant is uniformly distributed, so that the working efficiency and service life of the differential mechanism are improved; when the upper cover body is installed, the split arc plate is inserted into the injection pipe, the conical plate is shrunk into the movable groove, until the split arc plate is completely inserted, the snap ring is then clamped into the clamping groove to fix the split arc plate, prevent falling, the upper cover body is pre-fixed on the connecting cover body, ensure that the upper cover body is installed accurately, simplify the filling seat installation process, ensure stable connection, and reduce lubricant leakage.
