Bucket elevator type gearbox

TH-type bucket elevator chain type Product Overview:
TH series bucket elevator is a commonly used lifting equipment, the series bucket elevator chain forged as part of the drive, with strong mechanical strength, mainly used to hoist the powder and small particles and small bulk materials , different from the TD-belt bucket elevator, lift its larger, more efficient operation. Its often used to enhance a large proportion of the material. Widely used in metallurgical, chemical, building materials, mining, oil, food, feed, plastics, pharmaceutical and other industries.

Two, TH-type bucket elevator chain basic structure:
The machine is equipped with two kinds of hoppers: ZH-type (deep bucket) are generally used to transport wet, easy caking, throw harder materials, such as wet sand, sand, fertilizer, base fertilizer base powder. SH-type (deep bucket) are generally used to transport dry, easy to throw loose materials, such as cement, gravel, coal and so on. This machine is gearing has two forms, each equipped with ZJ reducer and ZQ reducer. ZJ-type shaft-mounted reducer directly sets the spindle axis head, eliminating the transmission platform, coupling, so that the compact, lightweight, and with internal shaped roll backstop, backstop and reliable, the noise reducer low, stable operation, and with the spindle floating installation can eliminate stress. TH-type bucket elevator maximum throughput 365m3 / h, maximum lifting height of 50m.

Three, TH-type chain bucket elevator main characteristics:
Transport volume, compared with the same bucket width HL type, transmission type increases the amount of TH nearly doubled. Adopted assembled sprocket. There are wheel rim connection is made with high strength bolts. Sprocket wear to a certain extent, you can unscrew the bolt, removable rim, easy to replace, saving and demolition materials, reducing maintenance costs. The lower part of the lever-type tensioning device weight, you can achieve automatic tensioning. After the first installation without adjustment, and can maintain a constant tension, thus ensuring the normal operation of the machine, to avoid slipping or off the chain. Traction member of HSLA park chain, after appropriate heat treatment, with high tensile strength and abrasion resistance, long service life.

The gearbox and gear reducers are used in bucket elevator is mainly of cycloidal gear motors, helical hevel industrial gearboxes and DCY China gearboxes.

How to select the gear reducers model correctly?

Selection of general speed reducer includes condition, select the type, determine the specifications and other steps.
In contrast, the type selection is more simple, while providing accurate reducer working conditions, master reducer design, manufacture and use of key common feature is a reasonable choice reducer correct specifications. Specifications choose strength, thermal equilibrium, the shaft extension portion radial load and other conditions to be met.

1. Selecting by mechanical power or torque (strength checking)
The biggest difference is GM reducer and special reducer design selection process is that the former applies to all sectors, but the deceleration only by a particular design of working conditions, so users need to consider the selection of different correction coefficients according to individual requirements plant selection should be based on the actual motor power (not the gear unit rated power) play nameplate; the latter according to the user's special conditions designed to consider factors that, the design has been made generally considered, as long as the selection using a power less than or equal reduction The power rating can be, the method is relatively simple.
2. the heat power balance checking
Universal reducer allowable thermal power values are (under normal ambient temperature of 20 ℃, per hour, 100%, continuous operation, the power efficiency of 100%), the maximum allowed by the lubricant equilibrium temperature (usually 85 specific working conditions ℃) determined. The condition is not at the same time pressing the corresponding coefficient (sometimes integrated into a coefficient) be amended.
3. Checking shaft extension portion bear radial load
Universal reducer often required to input shaft, an output shaft extending middle part withstand the maximum allowed radial load to be limiting and should be checked, the manufacturer shall propose bold and increase the bearing shaft diameter exceeds requirements.
