Embodiment Construction

[0024] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0025] Puller puller of the present invention uses the specific embodiment 1 of embracing chain, as Figure 1 to Figure 3 As shown, the puller using the embracing chain for the puller of the present invention includes a main frame body 1, and the main frame body 1 has two cantilever arms 11 that cantilever relatively outwards. The center position of the main frame body 1 is provided with a nut that fits the thread on the push rod 2, and the cantilever 11 is provided with a through groove 12 that runs through the upper and lower sides of the cantilever 11. The width of the through groove 12 is adapted to the diameter of the pull rod 3. So that the pull rod 3 can move in the through groove 12 . The pull rod 3 is a long screw with a hexagonal head at the upper end. The hexagonal head of the pull rod 3 stops on the upper side of the groove wall of the throu...

Abstract

The invention relates to a clasping chain for a pulley extractor. The clasping chain for the pulley extractor comprises a chain body used for clasping a belt pulley circumferentially. The chain body is composed of a plurality of chain links, and the chain links are detachably connected end to end. The chain links are provided with protrusions matched with belt grooves. Every two adjacent chain links are hinged through a protruding column arranged at one end of one chain link and a groove which is formed in one end of the other chain link and is matched with the protruding column. When in use, the chain body is connected with pull rods of the pulley extractor through connecting holes, the number of the chain links of the clasping chain can be adjusted to enable the clasping chain to adapt to belt pulleys of different diameters, and the problem that the clasping chain needs to be matched with multiple chucks of different specifications, and consequentially the cost of the pulley extractor is high is avoided.

Description

technical field [0001] The invention relates to a holding chain for a puller. Background technique [0002] The puller is used to pull out the pulley from the motor shaft. The structure of the existing puller is CN205148202 U, and the announcement date is a V-shaped single-groove pulley special disassembly tool disclosed in a Chinese patent on 2016.04.13. The dismantling tool includes a main frame, the two ends of the main frame are provided with through grooves through up and down, the upper ends of the two pull rods pass through the through grooves, and the upper ends of the pull rods are provided with nuts that stop on the upper end surface of the main frame body , the lower ends of the two pull rods are threadedly connected to the chuck. The chuck is composed of two semicircular clips, and the inner side is provided with a protrusion that can be stuck in the wheel groove. When in use, the two clips of the chuck pass through The bolted connection holds the pulley tightly...
