To teach you to choose suitable castor five elements

How to choose suitable castor, usually choose suitable wheel rack first consider the weight of the caster wheel bearing such as supermarkets, schools, hospitals, office buildings, hotels and other places, because the floor is good, smooth lighter, and handling of goods ( Each trundle bearing in 10 - 140公斤) , suitable to select (with a thin plate 2 - 4毫米) Stamping wheel rack plating, the wheel frame is light, flexible operation, quiet and beautiful, the plating wheel frame in accordance with the ball bearing arrangement is divided into double row bead and single bead. If often move or application of double row in the bead. 2, in the place such as factories and warehouses, cargo handling very frequently and heavier load ( Each trundle bearing in 280 - only 420公斤) Chooses to suitable for thick steel plate, 5 - 6毫米) Stamping hot forging and welding of double row ball wheel. 3, if used for carrying heavy objects such as textile, automobile factories, factory machinery factory and other places, because the charge big factories within walking distance, Each trundle bearing in 350 - only 1200公斤) , therefore, should choose to thick steel plate, 8 - 12毫米) After cutting wheel frame, welding activities wheel rack flat ball bearing and ball bearing on the floor, make the castor can withstand the heavy loading, flexible rotation, impact resistance, etc. Industrial casters is mainly refers to a caster wheel used in machinery factory or products, it can be advanced of imported reinforced nylon ( PA6） , super single wheel made of polyurethane, rubber, integral whole product has a high impact resistance and strength. Bracket of metal parts is made of high qualified steel plate after galvanized or chrome plated anticorrosive processing, internal installed using the method of integrated injection molding precision ball bearings. Users can can choose 3 mm, 4 mm, 5 mm, 6 mm steel plate for caster stents. Medical truckle to adapt to the requirement of hospital operation is light, flexible steering, elasticity, special ultra-quiet, abrasion resistance, winding and resistance to chemical corrosion, etc, mainly divided into light-duty castor, metal stents castor, STO all plastic stent castor, CPT medical two-wheel casters, and control of double brake castor castor and health care. 4. Bearing capacity calculation according to the design load carrying capacity to a single caster. Castor carrying capacity is the most fundamental and most critical requirement of castor, and actual use of differ in thousands ways, therefore, in the actual choice caster wheel bearing capacity, should have certain safety allowance, four wheel installed with the most commonly used, for example, often can choose according to the following two methods: according to the three castor full weight selection. One castor dangling, this method is suitable for the shipment or equipment in the process of mobile casters under the force of the large, poor ground condition, especially in the case of the total weight is bigger. 5. According to the four casters under 120% of the total weight. This method is suitable for the ground is in good condition, or equipment in the process of moving shipment, casters under the impact of smaller places. In particular, for the casters will be badly impact, not only to choose the caster wheel bearing capacity big, impact resistant structure and should choose different design. Castor: castor subject; One wheel group, is located in castor pivot of socket, the wheel set consists of the wheel, shaft rod, sealing body and fender, the trundle body is equipped with the cylinder block ahead, and concave is equipped with two embedded at the bottom of the tank, castor subject in castor main cylinder of the front concave groove, the groove is equipped with the chimeric grooves on both sides; Brake system, which is located in castor concave surface at the bottom of the main body, the brake system consists of brake shrapnel, lower brake knob and press the button type brake component combination; Must to the system, is located in castor concave surface at the bottom of the main body, the directional system includes positioning card, pedals and composite board combination; Steering gear disk, which is located in brake system above the gear disk brake shrapnel, the tooth disc brake shrapnel is a integrated, so the tooth plate upwards at the same time shift occlusal steering gear disk form card, make the castor can achieve the purpose of braking and steering motionless at the same time. The choice of castor wheels wheel material: first consider using the road, the size of the obstacles, the use of ground residual material ( Such as iron, oil) , environment conditions ( Such as high temperature and normal temperature or low temperature) And the wheels can bearing the weight of the different conditions, such as to determine the choice suitable wheel material. Use on the rough ground, should wear resistance and resilient rubber, polyurethane or super synthetic rubber wheels; Working in special high temperature or low temperature, or working environment temperature difference is very big, should choose metal wheels or special high temperature resistant wheels; Where the requirements to prevent the accumulation of electrostatic generation, had better use special anti-static wheel, also can choose metal wheel ( If the ground does not require protection, ; Work environment there are many corrosive medium, should choose to have good corrosion resistance of the wheel accordingly. / news_65。
