[0004] The existing reverse cover cannot well connect to the main oil circuit while avoiding the screw mounting hole. Even if the screw mounting hole is avoided, the embedded bolt installed at the end face may block part of the side surface oil circuit, resulting in insufficient oil supply. Some existing reverse covers can avoid the influence of the screw through the design of the main and sub-oil circuits, but the length of the oil circuit is greatly increased, which has a great influence on the oil injection pressure. The grease or oil may not flow uniformly to each channel, and the amount of oil injected each time will increase slightly to ensure sufficient lubrication. INVENTION CONTENTS

For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] As Figure 1 An oil path structure of a reverser, comprising a reverser cover 1 and a rotary plate 2 connected. The reverser cover 1 and the rotary plate 2 are connected at both ends of a sliding block 3 through screws, and the sliding block 3 is connected with a guide rail 4 through a steel ball. The above structure is a conventional structure of linear guide rail, which will not be described here.

[0028] As Figure 2The rotary plate 2 is provided with a main oil path 101 communicated with the channel 102, and the return cover 1 is provided with a first threaded hole 103 penetrating through and communicated with the main oil path 101 to form a first lubricating path. The lubricant is directly injected through the first threaded hole 103 on the return cover 1, and the lubricant enters the main oil path 101 and is evenly distributed to the four channels 102 of the return cover 1 through the main oil path 101. During the circulation of the steel ball in the return cover 1, the lubricant is brought into the channel 102 between the sliding block 3 and the track, so as to achieve the purpose of lubrication.

[0029] The upper end of the first threaded hole 103 is provided with a connecting groove 104 communicated with a secondary oil path, and the main oil path 101, the connecting groove 104 and the secondary oil path form a second lubricating path. Figure 4 The end surface of the return cover 1 close to the rotary plate 2 is provided with a non-penetrating connecting groove 104 communicated with the first threaded hole 103. The connecting groove 104 is a square groove, an arc-shaped groove or a polygonal groove formed by connecting multiple straight lines. In this embodiment, the connecting groove 104 is a square groove, and the connecting groove 104 serves as a communication between the secondary oil path and the main oil path 101. The shape is not limited to the structure in this embodiment, and other existing regular or irregular grooves can also achieve the communication function.

[0030] The secondary oil path includes a first oil path 105 and a second oil path 106. One end of the first oil path 105 is communicated with the connecting groove 104, and the other end is communicated with the second oil path 106. The end of the second oil path 106 is communicated with the second threaded hole 107 on the return cover 1. The second threaded hole 107 and the first threaded hole 103 are vertically arranged. The second threaded hole 107 in this embodiment is arranged on the right side surface of the return cover 1. Similarly, the secondary oil path can be arranged to the left side, and the second threaded hole 107 is arranged on the left side surface of the return cover 1. The number and direction of the secondary oil path can be determined according to the specific working conditions.

[0031] An oil nozzle is installed on the second threaded hole 107. The second threaded hole 107 is communicated with the main oil path 101 through the second oil path 106, the first oil path 105 and the connecting groove 104. The lubricant is injected through the oil nozzle, and then enters the connecting groove 104 along the second path and the first path in sequence, and finally enters the main oil path 101 through the connecting groove 104. After entering the main oil path 101, the working principle is the same as that of the first lubricating path.

[0032] The first oil path 105 and the second oil path 106 are connected to form a secondary oil path with a stepped structure. In order to avoid interference between the mounting threaded hole on the return cover 1 and the first oil path 105, the hole diameter of the first oil path 105 is designed to be smaller than the hole diameter of the second oil path 106, so that the second threaded hole 107 can be arranged on the return cover 1. Figure 2 and Figure 3As can be seen from the drawings, the first oil passage 105 with a smaller aperture has a gap between the mounting threaded hole (the mounting threaded hole is located on the right side of the first threaded hole 103), which can avoid the mounting threaded hole and well connect the auxiliary oil passage to the main oil passage 101, and avoid the end face mounting plug to block part of the first oil passage 105.

[0033] In summary, the oil passage structure of the reverser can avoid the influence of the threaded hole on the side oil passage, solve the problem that the auxiliary passage cannot be connected with the threaded hole, and ensure that the lubricant can stably and uniformly reach the groove.

[0034] The above describes the ideal embodiment of the utility model as an inspiration, and through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the utility model. The technical scope of the utility model is not limited to the content in the specification, and must be determined by the scope of the claims.
