Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil injection of a transmission shaft intermediate support assembly, in particular to an oil injection device for an automobile transmission shaft intermediate support assembly. Background Art
[0002] The drive shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial. Generally, the drive shaft must undergo a dynamic balance test and be adjusted on a balancing machine before leaving the factory. For front-engine, rear-wheel drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can be composed of several sections, and the sections can be connected by universal joints.
[0003] In the existing transmission shaft intermediate support assembly oiling device, butter is generally squeezed and injected into the interior of the intermediate support. Generally, after a specified period of use, it is necessary to apply butter for lubrication and maintenance. However, when oiling, 30g is generally specified as the optimal oil injection amount, which cannot be too much or too little. The existing device cannot ensure that the oil injection amount is maintained at around 30g, and cannot achieve quantitative oil supply, which can easily lead to excessive or insufficient oil injection.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content
[0005] In view of the above background technology, the prior art has the disadvantages that it cannot ensure that the oil injection amount is maintained at about 30g, cannot achieve quantitative oil supply, and easily leads to the disadvantages of too much or too little oil injection.

[0007] By adopting the above scheme, the cover body is positioned by the shell, and the spring is fixed to the bottom surface of the cover body, the extrusion plate is fixed to the bottom end of the spring, and the extrusion plate is driven to move by the elastic force of the spring, and the extrusion plate squeezes the butter, so that the butter can be squeezed out of the shell, the threaded rod 1 is positioned by the extrusion plate, and the threaded rod 1 and the inside of the cover body are set to be threadedly connected, and the ball is fixed to the bottom end of the threaded rod 1, and the ball can be driven to descend by rotating the threaded rod 1, and the conical block is installed on the inner wall of the output pipe at the lower end of the shell. When the ball descends to fit with the inner wall of the conical block, the butter will not be squeezed out of the shell because the ball seals the conical block.
[0008] Optionally, the outer surface of the cover body is fixedly connected with fixed blocks 1 arranged at equal distances, and the interior of each of the fixed blocks 1 is rotatably connected with a threaded rod 2.
[0009] By adopting the above solution, the fixing block 1 is placed on the outer surface of the cover body, and the threaded rod 2 is rotatably connected to the inside of the fixing block 1. The positioning and limiting effect of the threaded rod 2 is achieved through the fixing block 1. There are two fixing blocks 1 and two threaded rods 2 in total.
[0010] Furthermore, the outer surface of each of the threaded rods 2 is threadedly connected to a fixing block 2, and a side of each of the fixing blocks 2 that is close to each other is fixedly connected to the outer surface of the shell.
[0011] By adopting the above scheme, the fixed block two is positioned by the surface of the threaded rod two, and a threaded connection is set between the threaded rod two and the fixed block two, so that the shell and the fixed block two are fixed to achieve a limiting effect on the fixed block two. By rotating the threaded rod two and the threaded connection between the threaded rod two and the fixed block two, the fixed block one can be driven to rise or fall, and then the cover body can be driven to rise or fall, which is convenient for opening the cover body for loading and unloading.
[0012] Furthermore, the bottom end of the shell is fixedly connected to a containing cylinder, the bottom end of the containing cylinder is fixedly connected to an output cylinder, and the outer surface of the output cylinder is fixedly connected to a hand piece.
[0013] By adopting the above scheme, the containing cylinder is placed at the bottom end of the shell, and the output tube at the bottom end of the shell is connected to the containing cylinder. The surface of the containing cylinder is engraved with scales. When the containing cylinder is filled with butter, it reaches the set number of grams. The output cylinder is connected to the containing cylinder, and a hand piece is installed on the surface of the output cylinder. The hand piece makes it easy to hold the output cylinder and prevents slipping.
[0014] Furthermore, a rotating shaft is rotatably connected inside the output cylinder, and a spiral sheet is fixedly connected to the outer surface of the rotating shaft.
[0015] By adopting the above solution, the rotating shaft is placed inside the output cylinder, and the spiral piece is fixed on the surface of the rotating shaft. The spiral piece can be driven to rotate by rotating the rotating shaft, and the butter is transferred out of the output cylinder by the rotation of the spiral piece.
[0016] Furthermore, the output end of the output cylinder is fixedly connected to a pipeline, and the other end of the pipeline is fixedly connected to a connecting piece.
[0017] By adopting the above solution, the pipeline is installed at the output end of the output cylinder, the butter is transferred to the inside of the pipeline through the spiral sheet, and output through the connecting piece, finally achieving the oil injection effect.
[0018] Furthermore, an intermediate support is provided below the shell, an oil inlet is fixedly mounted on the outer surface of the intermediate support, the outer surface of the oil inlet is snap-fitted to the outer surface of the connecting piece, and a universal joint is fixedly connected to the right end of the intermediate support.
[0019] By adopting the above scheme, an oil inlet is installed on the surface of the middle support. Through the connection between the oil inlet and the connecting piece, grease is transferred to the inside of the oil inlet to achieve oil filling. The oil inlet is also installed on the surface of the universal joint to facilitate lubrication of the universal joint.
[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0021] 1. The utility model places butter inside the shell by arranging components such as a spring, an extrusion plate, a threaded rod, a sphere, and a conical block. When the cover body contacts the shell, the extrusion plate is pressed downward by the elastic force of the spring, and the butter is squeezed out of the shell through the extrusion plate and discharged into the inside of the containing cylinder through the conical block. When the inside of the containing cylinder is full, the threaded rod is rotated to be threadedly connected with the cover body. At this time, the threaded rod drives the sphere to descend, and the sphere contacts the conical block to seal the conical block. At this time, the butter will not continue to flow out of the shell. The containing cylinder of corresponding size is used according to actual needs, thereby realizing the effect of quantitative oil supply of the device and preventing excessive oil injection.
[0022] 2. The utility model provides an output cylinder, a rotating shaft, a spiral piece, a hand piece and other components, and the butter falls into the containing cylinder. At this time, if the rotating shaft is not rotated, the butter will not be transferred. The rotating shaft drives the spiral piece to rotate, and the rotation of the spiral piece drives the butter to be transferred to the inside of the pipeline. The butter is injected into the inside of the middle support through the connection between the connecting piece and the oil inlet. The installation of the hand piece facilitates the enhancement of the friction of the handheld output cylinder to prevent slipping when the rotating shaft is rotated.
