Gearbox

The gearbox is a gearbox that changes the transmission ratio and direction of movement. Located between the clutch and the central drive. The main function is: under the condition of constant engine speed and torque, change the driving force and driving speed of the vehicle (shift); enable the vehicle to run backwards (reverse); the engine can stop without stalling (neutral). According to the transmission type, the gear type gearbox can be divided into three types: two-axis type, three-axis type, and composition type. The two-shaft type has two main shafts (not including the reverse shaft), which only go through a pair of gear reduction.
  • Description
  • Hebei Shengli Casting Industry Co., Ltd. provides various types of ductile iron castings and gray iron castings. The industry involves auto parts, agricultural machinery parts, construction machinery parts, train and railway parts, cast iron parts for agricultural water conservancy and electric power, etc. Shengli Casting Industry has the production and rough processing capabilities of cast iron parts, advanced production equipment, complete testing equipment, and supports cooperation methods such as drawing customization, sample customization, OEM, etc.

    Bearing frame product description:

    The gearbox is a gearbox that changes the transmission ratio and direction of movement. Located between the clutch and the central drive. The main function is: under the condition of constant engine speed and torque, change the driving force and driving speed of the vehicle (shift); enable the vehicle to run backwards (reverse); the engine can stop without stalling (neutral). According to the transmission type, the gear type gearbox can be divided into three types: two-axis type, three-axis type, and composition type. The two-shaft type has two main shafts (not including the reverse shaft), which only go through a pair of gear reduction. The three-axis type has three main shafts (first shaft, intermediate shaft, and second shaft), which go through two pairs of gear reduction. The composition is composed of two transmission cases in series or parallel to obtain more gears with fewer gears.

    basic structure of gearbox: 1-input shaft clutch, 2-input shaft, 3-input shaft first driving gear, 4-input shaft second driving gear, 5-output shaft front section, 6-input shaft reverse driving gear, 7-lock clutch sleeve drive shaft, 8-intermediate shaft, 9-lock clutch sleeve, 10-output shaft front spline, 11-output shaft rear spline, 12-output shaft clutch, 13-output shaft rear section, 14-lock clutch sleeve return spring, 15-lock clutch sleeve shift shaft, 16-reverse gear shift shaft, 17 reverse gear sliding gear, 18-output shaft second sliding gear, 19-output shaft first sliding gear.

    During long-term use, due to frequent gear shifting, the parts in the gearbox will inevitably be worn and deformed, resulting in difficulties in shifting the gearbox, automatic shifting, noise during operation and other malfunctions, which affect the use. Therefore, in daily use, it is necessary to regularly check the working conditions of the gearbox body under full load operation, observe whether the gearbox body is stable, whether there is abnormal clearance and noise, and find out the cause for adjustment or repair in time.
