A camera assembly includes a motor configured to generate a driving power; a motor shaft that extends from the motor, such as to define a first axis, and is configured to rotate by the driving power of the motor; a pulley configured to rotate on a second axis, that is spaced from the first axis, according to rotation of the motor shaft; a belt configured to couple the motor shaft and the pulley, and convert the rotation of the motor shaft to rotation of the pulley, and tension of the belt applies a force to the motor shaft in a direction towards the second axis; a camera module configured to be mounted on the pulley and rotate together with the pulley; and an elastic body configured to apply a biasing force to the motor shaft such as to bias the motor shaft in a direction away from the second axis.

A belt tensioner for a belt system having a compression spring internal to the tensioning arm, the tensioning arm pivotable in relation to the pivot shaft and the tensioner base. The compression spring provides an axial force against an axially slidable hub bearing, which moves to accommodate variations in spring force and/or dimensional changes.

A tensioner that has a base adapted to be secured to an engine, and at least one arm hinged to a pin fixed to the base and bearing a pulley adapted to cooperate with a belt of a transmission of the engine, and elastic means for pushing the at least one arm in a direction so as to keep the pulley against the belt. The tensioner has sensor means for acquiring in real time a plurality of data relating to the tensioner to estimate the state of efficiency of the same.

A belt-tensioning device includes an electric machine having a drive belt pulley, which is driven about a drive axis, and a further drive belt pulley, where an endless belt wraps around the drive belt pulleys. The device has a housing in which a first and a second spring arm are mounted, in each of which spring arms a tension roller having axes of rotation which are parallel to the drive axis is rotatably mounted. The spring arms are supported against one another and press the endless belt together via the tension rollers in the region of the drive belt pulley. A first and a second further spring arm are provided adjacent to the spring arms which are adjustable by an adjustment element such that the spring forces of the further spring arms either do or do not support the spring forces of the spring arms acting on the endless belt.

A pickup unit of an agricultural baler that includes a reel with a plurality of tines configured for lifting a crop material from a field, the reel is rotatable in an operating direction and a reverse direction, and a drive system configured for driving the reel. The drive system includes a gearbox configured for receiving motive power from a power take off (PTO) shaft, a drive shaft operably connected to the gearbox, and a first clutch connected to the drive shaft. The first clutch is configured for operably disconnecting motive power to the reel so that the reel is manually rotatable as the PTO shaft remains operably engaged with the gearbox.

A sheave/sprocket tension adjustment and alignment tool (STAT) for adjusting alignment between a sheave/sprocket of a motor and a sheave/sprocket of an application machine includes a plate, a securing unit, and an adjusting unit. The plate has a first side and a second side, each of which is an opposite side of a plane of the plate. The securing unit is coupled to the first side of the plate and is configured to protrude in a first direction from the first side of the plate. The adjusting unit is coupled to a second side of the plate. The adjusting unit includes an adjustable protrusion that is configured to adjustably protrude in a second direction, which is substantially parallel to the plane of the plate.

A pulley device provides a pulley, and a bearing. The pulley has at least one C-shaped pulley part having an inner portion mounted on the bearing, an outer portion having an outer cylindrical surface dedicated to interact with a belt or a chain, and an intermediate portion extending substantially radially between axial ends of inner and outer portions on one axial side of pulley device. A grip surface portion is provided to one surface among the outer cylindrical surface of the outer ring and the inner cylindrical surface of the inner cylindrical portion of the pulley part, the grip surface portion including a plurality of indentations and recesses.

A lubrication arrangement includes at least one housing, at least one shaft, at least one bearing system configured to hold the at least one shaft in the at least one housing and to permit the at least one shaft to rotate, lubricant distributed in the at least one housing with the rotation of the at least one shaft, and a lubricant deflector provided in a stationary manner relative to the at least one housing above the at least one shaft. The lubricant strikes against the lubricant deflector and, by action of gravity, the lubricant is conducted to the at least one bearing system of the at least one shaft so that the at least one bearing system is supplied with the lubricant.

A motorized wheelbarrow including a motor and a drive pulley that rotates when the motor is operating. The motorized wheelbarrow also includes wheels and a drive train assembly for transmitting power from the motor to the wheels. The motorized wheelbarrow also includes a clutch assembly movable between a connected condition, in which the motor and the drive train assembly are connected by the clutch assembly, and a disconnected condition, in which the motor and the drive train assembly are not connected with each other, and a brake assembly movable between an engaged condition, in which the brake assembly resists rotation of the wheels, and a disengaged condition, in which the brake assembly does not resist rotation of the wheels. Both of the clutch assembly and the brake assembly are controlled by a single control assembly so that the clutch assembly and the brake assembly are mutually functionally exclusive.

Embodiments of the present disclosure include a drive belt tensioner configured to adjust tension in a drive belt of a blower assembly for a heating, ventilation, and/or air conditioning (HVAC) system. The drive belt tensioner includes a mounting bracket configured to couple directly to a blower housing that is configured to house a blower of the blower assembly. The drive belt tensioner further includes an idler pulley configured to contact the drive belt. A position of the idler pulley is adjustable relative to the mounting bracket to enable adjustment of the tension in the drive belt.
