Swelling sets the company, state-hung brand (certified), expansion sleeve is provided by state-hung Machinery Co., Ltd. in Guangzhou. Hung Machinery Co., Ltd. Guangzhou state (www.gzbhjx.com) is specialized in the "Bushes, industrial belts, expansion sets, timing belt pulleys," the enterprise, the company of "honesty, hard service" concept, to provide you with The most high-quality products and services. Welcome to inquire! Contact: Manager Ma. Sets up the connection sleeve installation (1) projecting end of the spindle bore and large gear clean with fine gauze and cotton yarn, check its various dimensions, after confirmation with gasoline or carbon tetrachloride for cleaning. After cleaning, the spindle bore surface and gear lubricant evenly coated with a thin layer of lubricant shall not contain molybdenum disulfide. (2) through the inside of the cover, suit up on the spindle, the large gear lifted slowly installed in place, the large gear installation process to keep the gap between the same spindle. (3) the large gear and shaft sleeve again at cleaning up, will loosen the set screw up big gear smoothly into the bore, hand tighten the screws, and then four times with different setpoints set torque wrench fastening. 1st pretension, set torque wrench setting is 310 N, the eleven hex bolts fastening bolts need diagonal cross, evenly tighten, but use the dial indicator to detect surface and the large gear spindle bore distance from the surface are equal. 360 ° circumferential surface inspection records should be subject to error any time to adjust. 1st press 310N tighten all bolts after all, and then set the limit torque wrench in the 2nd fastening 465N, measurement records, and so on. 3rd fastening setting is 930N, 4th fastening setpoint 930N final review. The use of multi-channel sets up the connection, 2, 3 sets of tightening up the order and set up exactly the same as the first shelf swelling sets, but each channel set up installed at different depths, they need different lengths afterburner rod. After all tightening is completed, the large gear cover equipment, fastening bolts can be. For the cover without fortification set up, to be coated with anti-rust oil on a regular basis in its exposed end face and the screw head. When set to be torn up, loosen all the screws, but do not tighten all the screws out. Pull out the screw into the ring before the pressure in the auxiliary screw, pull gently tapping screw head swelling sets of companies that make up the loose sleeve expansion sleeve, then pull the screw, you can be pulled up the sleeve. Up tight sets of installation, removal and protection 1. Installation: expansion sets are factory coated with oil, can be installed directly. First, other pieces ① flange holes on three bolts screwed into the installation ④ uniformly distributed along the circumference, the inner sleeve ①, ② open the top coat. Then the expansion sets into the hub bore design position, using the dynamometer wrench to tighten the bolts and tighten each bolt method is a time to tighten the rated torque 1/4 swelling sets wholesale, tighten the order to open the seam place for the community, about crossing symmetry has tightened in order to ensure that the rated torque value. 2. Remove the following: First of all when removing the bolts loosen laps. Then screw in the demolition of the cross bolt screwed into the top ④ loose expansion sets. 3. Protection: expansion sets to prevent contamination during installation, do not use MoS2 oil. In the open-air job or a poor work environment machines should be regularly coated antirust grease on the end face of the expansion sets and bolts exposed, should use good rust resistance type expansion sets. Swelling link sets is a new type of modern advanced machine parts. Is widely used to implement parts of today's international and shaft coupling, by tightening the screws 12.9 high strength pressure and friction between surfaces produce inclusive to achieve a new keyless hitch load transmission.
