SOLIDWORKS Lip and Groove Tool Tutorial

Here we have a concise yet comprehensive SOLIDWORKS Lip and Grove tool tutorial. Lip and Groove features are very common on plastic items like enclosures or cases where two or more parts have to fit together snugly. These simple features are an easy way to ensure that parts are correctly aligned without adding much complexity to the design or manufacture stages. Like many features in Solidworks Lips and Grooves can be manually modelled but there is also a specialist tool that speeds up adding these details.

Using the Lip and Groove Tool

As the name suggests – the Lip and Groove Feature can be used to add a Lip or a correspondng Groove. Either feature can be added independently and the process is very similar for both. First, select the tool from Insert>Fastening Feature>Lip/Groove.

The user then needs to select a body on which to add the feature, and they can choose to add either a Groove, or a Lip. A direction also be set for the Lip/Groove but often this isn’t needed because the exact edge is selected at the next stage.

Once the body has been selected the user then chooses a face to cut the groove into, or to add the lip onto, and also selects an edge to align the feature. The tangent propagation option can also be used to make the lip or groove automatically follow multiple edges.

Once these selections are made, all that remains is for the user to set the exact size of the lip or groove with reference to the visual guide.

Lip and Groove Top Tips

Solidworks 2021 - Intensive training course for complete beginnersThe Lip and Groove Feature is the simplest way to add lips and corresponding grooves to your parts. Follow these steps to use it:

  • Select the tool from Insert>Fastening Feature>Lip/Groove
  • Choose a body for the feature, and select either a lip or groove
  • Select the face and edge for feature. Use tangent propagation, if needed, to easily select multiple connected edges
  • Set the exact size of the lip/groove by following the visual guide

Happy modelling and rendering!

  1. FAG NU356E.M1 bearing

    Generally speaking, rolling bearings with tight fit interference installation must be close to the shaft shoulder. So how to test it? According to our company’s knowledge of bearings, let’s share the detection methods of the tightness of rolling bearings and shaft shoulders. I hope that it will be helpful to everyone’s bearing installation.

    (1) Lighting method. This method is to align the lamp at the bearing and shaft shoulder, and judge according to the light leakage. If there is no light leakage, it means the installation is correct; if there is even light leakage around the shaft shoulder, it means that the rolling bearing is not close to the shaft shoulder, and pressure should be applied to the rolling bearing to make it close; if there is some light leakage, it means that the bearing installation is inclined, and a hand hammer or copper rod can be used Or the sleeve knocks on the inner ring of the bearing to gradually settle.

    (2) Thickness gauge inspection method. The thickness of the thickness gauge should start from 0.03mm. During the inspection, try to insert several places on the entire circumference of the bearing inner ring end face and the shaft shoulder. If there is a gap and it is very uniform, it means that the bearing is not installed in place. The bearing inner ring should be pressurized to make it close to the shaft shoulder; if it is enlarged The pressure is also not tight, indicating that the rounded corners of the rounded part of the journal are too large, and the bearing is stuck. The rounded corners of the journal should be trimmed to make it smaller; if it is found that the thickness of the end face of the bearing inner ring and the individual parts of the bearing shoulder can be Passed, it means that it must be disassembled, repaired, and reinstalled at this time.

    If the bearing is installed in the bearing housing hole with an interference fit, when the outer ring of the bearing is fixed by the housing hole shoulder, whether the end face of the outer ring is tight with the housing hole shoulder end and whether the installation is correct can also be checked with a thickness gauge.

    Such as: inspection after installation of thrust bearing

    When installing the thrust bearing, check the verticality of the shaft ring and the shaft center line. The method is to fix the dial indicator on the end surface of the case, make the contact of the indicator rest on the raceway of the bearing shaft ring while rotating the bearing while observing the dial indicator pointer. When the box shell hole is deep, it can also be inspected with an extended dial gauge.

    When the thrust bearing is installed correctly, its seat ring can automatically adapt to the rolling of the rolling elements to ensure that the rolling elements are located in the upper and lower ring raceways. If it is installed backwards, not only the bearing will not work properly, but also the mating surfaces will be severely worn. Since the difference between the shaft ring and the seat ring is not very obvious, you should be extra careful during the assembly and make no mistake. In addition, there should be a gap of 0.2-0. 5mm between the seat ring of the thrust bearing and the bearing seat hole to compensate for the errors caused by inaccurate parts processing and installation. When the center of the bearing ring is shifted during operation , This gap can ensure its automatic adjustment, avoid touching and rubbing, and make it operate normally. Otherwise, it will cause severe damage to the bearing.
