Description

Technical Field

[0001] The utility model relates to the field of grease coating devices, in particular to a grease coating device for a clutch actuator. Background Art

[0002] Our company has developed a clutch actuator, patent number CN220204636U, as shown in the attached figure of the specification. Figure 1 、 Figure 2 As shown, the clutch actuator includes a front housing and a rear housing. The front housing includes a worm gear cavity and a worm cavity. A fan-shaped worm gear is provided in the worm gear cavity. A worm is provided in the worm gear cavity. The fan-shaped worm gear and the worm are meshed. The end of the worm gear is connected to the motor power, and the fan-shaped worm gear is connected to the gearbox power, thereby achieving the purpose of controlling the gearbox through the motor, worm gear and worm in sequence.

[0003] A connecting arc surface is formed at the connecting position between the worm wheel chamber and the worm cavity. The worm passes through the connecting arc surface and partially extends into the worm wheel chamber. The projection of the connecting arc surface on the bottom of the worm wheel chamber is an arc (that is, the connecting arc surface and the bottom of the worm wheel chamber are perpendicular). The projection of the connecting arc surface on the vertical plane of the bottom of the worm wheel chamber is an ellipse. When the shell is placed horizontally, the opening of the worm wheel chamber faces upward, which is convenient for placing the fan-shaped worm wheel, the bottom of the worm wheel chamber is horizontal, and the central axis of the worm is horizontal.

[0004] In order to reduce the friction of the worm gear and extend the mechanical life, it is usually necessary to apply grease after installing the worm gear in the housing and before installing the fan-shaped worm gear, and then install the fan-shaped worm gear into the worm gear cavity to make it mesh with the worm gear.

[0005] However, although the grease falls on the worm gear during greasing, once the clutch actuator is operated after assembly, it will be found that some of the grease is thrown onto the side wall of the worm cavity. The grease does not fully act on the worm gear meshing position, resulting in low lubrication efficiency. Utility Model Content

[0006] The utility model aims to provide a grease coating device for a clutch actuator to improve the lubrication efficiency of the grease.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a clutch actuator greasing device, including a greasing mechanism and a greasing tooling, the greasing tooling includes a first housing tooling, the first housing tooling is used to fix the housing so that the housing is tilted, and the greasing mechanism is used to grease the connecting arc surface edge of the housing.

[0008] The beneficial effects of this program are:

[0009] 1. When applying grease, if the housing is placed horizontally, the connecting arc surface is perpendicular to the horizontal plane. After the grease drips, it is difficult to adhere to the edge of the connecting arc surface and can only fall directly on the worm. Usually, an excessive amount of grease needs to be applied to ensure long-term lubrication. However, if filtered grease is applied to the worm at this time, the grease will easily fall into the worm cavity under the action of gravity, which will reduce the lubrication efficiency.

[0010] Therefore, in this solution, the housing is tilted by the first housing fixture so that the connecting arc surface is also tilted to a certain extent, so that the grease can fall on the connecting arc surface without being easily dropped. That is, the grease is applied in a circle around the connecting arc surface instead of being applied directly to the worm.

[0011] Then remove the housing and place it horizontally. At this time, put the sector worm gear into the worm gear cavity and make it mesh with the worm. At the same time, scrape the grease on the edge of the connecting arc surface downward into the meshing position of the worm gear and the worm gear and the worm gear cavity. Since the connecting arc surface is no longer tilted at this time, excess grease will not be transferred into the worm gear cavity, and most of the grease is pressed into the worm gear cavity by the lower side of the sector worm gear.

[0012] 2. When the lubricating oil consumption at the worm gear meshing position decreases, the grease in the worm gear cavity will overflow to the meshing position, replenishing the grease at that position to a certain extent.

[0013] Furthermore, the grease applying tool also includes a worm gear tool, which is used to fix the sector-shaped worm gear, and the grease applying mechanism is used to apply grease to the side of the sector-shaped worm gear tooth surface close to the bottom of the worm gear cavity.

[0014] Furthermore, the total weight of grease applied by the grease applying mechanism to the clutch actuators of the same model is a fixed value.

[0015] Furthermore, the grease applying tool includes a second housing tool, which is used to fix the housing so that the end of the worm of the housing close to the motor faces upward.

[0016] Furthermore, it also includes a platform, which includes a workpiece area and a grease coating area. The grease coating mechanism is arranged in the grease coating area. The platform is provided with a first track and a second track spanning the workpiece area and the grease coating area. A first walking mechanism is slidingly provided on the first track, and a second walking mechanism is provided on the second track. The first shell tooling and the worm gear tooling are arranged on the first walking mechanism, and the second shell tooling is arranged on the second walking mechanism.

[0017] Furthermore, the first shell tooling includes a plurality of vertical plates arranged in parallel, and the upper surfaces of the vertical plates match the shape of the lower surface of the inclined shell.

[0018] Furthermore, the shell inclination angle on the first shell tooling is 10-45°.

[0019] This solution also has the following effects:

[0020] 1. The grease application position of the sector worm gear is on the side of the tooth surface close to the bottom of the worm gear cavity, that is, the lower side of the tooth surface of the sector worm gear. The friction between the sector worm gear and the edge of the connecting arc surface when installing the sector worm gear is used to hang the grease on the lower side to the upper side of the tooth surface, so that the grease evenly covers the tooth surface; if the grease on the tooth surface is evenly applied in advance, the grease on the lower side of the tooth surface will be scraped away during installation, resulting in insufficient grease on the lower side of the tooth surface.

[0021] 2. The greasing speed of the greasing mechanism is usually fixed. In this solution, the total weight of the greasing is fixed. That is, by measuring the total weight after greasing and installing the fan-shaped worm gear, it can be determined whether the greasing speed is too fast or too slow, so as to adjust the greasing speed in time to maximize the greasing efficiency.

[0022] 3. The second housing tooling is used to fix the housing, and grease the housing close to the motor end through the grease coating mechanism.

[0023] 4. Place the shell on the first walking mechanism or the second walking mechanism in the workpiece area, and then move the first walking mechanism or the second walking mechanism to the grease coating area for grease coating. Grease coating and placement of tooling are divided into zones to avoid mutual interference. BRIEF DESCRIPTION OF THE DRAWINGS
