specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 with figure 2 Describe this embodiment, a sealed bearing grease leakage test loading device described in this embodiment includes a loading handwheel 1, a positioning sleeve 2, a loading spring 3, a loading stopper 4, a loading screw 5 and a thrust bearing 6, and the loading handwheel 1 , thrust bearing 6, positioning sleeve 2, loading spring 3, and loading stop iron 4 are set on the loading screw rod 5 successively from bottom to top.

[0008] In this embodiment, the lower surface of the positioning sleeve 2 has a mounting groove, and the shaft ring on the upper part of the thrust bearing 6 is embedded in the mounting groove on the lower surface of the positioning sleeve 2, so that the thrust bearing 6 is positioned.

[0009] In this embodiment, a pressure sensor is arranged above the loading stopper 4 .

[0010] The technical effect of this embodiment is: by rotating the loading handwheel 1, the force is evenly tra...

specific Embodiment approach 2

[0011] Specific implementation mode two: combination figure 1 with figure 2 To illustrate this embodiment, a groove 2-1 is formed in the middle of the upper surface of the positioning sleeve 2 of the loading device for a sealed bearing grease leakage test in this embodiment, and the lower end of the loading spring 3 is inserted into the groove 2-1.

[0012] The technical effect of this embodiment is: such setting prevents the loading spring 3 from shaking during the test and avoids errors in the test. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0013] Specific implementation mode three: combination figure 1 with figure 2 To illustrate this embodiment, a plurality of anti-slip grooves 1-1 are evenly distributed on the outer wall of the loading hand wheel 1 of the loading device for a grease leakage test of a sealed bearing described in this embodiment.

[0014] The technical effect of this embodiment is: such setting increases the friction between the operator's hand and the outer wall of the loading handwheel 1, so that the operator can hold the loading handwheel 1 firmly. Other components and connections are the same as those in the second embodiment.

Abstract

The invention provides a loading device for a sealed bearing grease leakage test and relates to a sealed bearing loading device. The loading device for the sealed bearing grease leakage test aims to solve the problems that due to the fact loading is conducted in the mode that a nut is rotated through a spanner in an existing sealed bearing grease leakage test, the loading adjusting time is long, the work efficiency is low and scratching is prone to occurrence. The loading device for the sealed bearing grease leakage test comprises a loading hand wheel, a locating sleeve, a loading spring, loading stop iron, a loading screw and a thrust bearing, wherein the loading screw is sleeved with the loading hand wheel, the thrust bearing, the locating sleeve, the loading spring and the locating iron in sequence from bottom to top. The loading device is applied to the sealed bearing grease leakage test.

Description

technical field [0001] The invention relates to a sealing bearing loading device, in particular to a sealing bearing grease leakage test loading device. Background technique [0002] The sealed bearing grease leakage test needs to be run for five to ten minutes under the condition of load during the test process. The original test loading method is to use the wrench to rotate the nut to push the spring to load. Due to the small radius of the nut, the wrench to rotate the nut cannot make a circle. Movement, so there are many small amplitude repetitions, long loading and adjustment time, and low work efficiency. At the same time, the speed of the grease leakage test is generally between 4000 and 10000r / min, and the test spindle is driven by a belt. Due to the test spindle and the loading spring The rods are on the same side, and the distance is relatively close, so it is easy to touch the transmission shaft when the wrench is lowered, and it will be scratched under high-speed ...
